A diaphragm is a flexible, pressure-responsive element that transmits force to open, close, or control a valve. Diaphragm valves are related to pinch valves, but use an elastomeric diaphragm, instead of an elastomeric liner in the valve body, to separate the flow stream from the closure element.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:image {\"align\":\"center\",\"id\":19395,\"sizeSlug\":\"full\",\"linkDestination\":\"none\"} -->\r\n<figure class=\"wp-block-image aligncenter size-full\"><img class=\"wp-image-19395\" src=\"https:\/\/zecovalve.com\/wp-content\/uploads\/2022\/07\/20220708083634-62c7ec92aba44.jpg\" alt=\"\" \/><\/figure>\r\n<!-- \/wp:image -->\r\n\r\n<!-- wp:heading -->\r\n<h2>How do Diaphragm Valves Work?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nDiaphragm valves are simple in construction and operation. A valve actuator is in contact with the inner membrane (or \u201cdiaphragm\u201d) of the valve in its open position. When the user desires the valve to be shut, the actuator is pressed and\/or turned and the membrane is pushed into the edge of the solid damn, closing the valve. Certain diaphragm valves can also have half open\/restricted positions where the membrane is partially closed, allowing a throttled flow through the valve. In the next section, we will examine the broad categories of diaphragm valves and where they are most useful.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Types of Diaphragm Valves<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Weir-Type Diaphragm Valves<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe weir-type diaphragm valve is one of the most common designs available and is what is shown in Figure 2, above. The raised lip\/saddle design is best suited for small flow control and is kept leak-proof thanks to the bonnet over the diaphragm and actuator. This design is optimal for dangerous or corrosive liquid and gas, as any failure with the membrane will be kept contained by this bonnet. Also, the sloped body makes this valve inherently self-draining, but this draining can happen in both valve directions which may not be optimal for some applications. The weir-type valve is mostly specified for clean, homogenous fluids, as viscous slurries and sediments may build up on either side of the saddle. They are most often found in processes such as food\/chemical, gas production, corrosive, and water applications.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Straight Through Type Diaphragm Valves<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe straight-through diaphragm valve is structurally similar to weir-types; however, it does not contain the characteristic saddle and instead has a completely straight pathway. Their membranes are typically more flexible and allow for farther travel distance, as it must touch the very bottom of the valve. These valves must often be serviced\/replaced, as their lifespan is typically less than weir-type designs due to their more flexible membranes. Straight-through diaphragm valves are used for slurries, viscous fluids, and other applications where blocking must be reduced. They are also useful for bi-directional flow regimes, as there is no saddle to impede swift changing from inlet to outlet.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Diaphragm Valve Parts<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe components of diaphragm valves are the following:\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Diaphragm Valve Bonnet<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe bonnet serves as the top cover and is bolted to the valve body. It protects the compressor, stem, diaphragm, and other non-wetted components of the diaphragm valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Diaphragm Valve Body<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe valve body is the component directly connected to the pipeline wherein the fluid passes. The flow area inside the valve body depends on the type of diaphragm valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBoth the valve body and bonnet are constructed from strong, rigid, and corrosive resistant materials.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Diaphragm Valve Diaphragm<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe diaphragm is made from a highly elastic polymeric disc that moves down to touch the bottom of the valve body to limit or obstruct the passage of fluid. The diaphragm lifts if the fluid flow rate is to be increased or the valve is to be fully opened. The fluid flows underneath the diaphragm. However, this component limits the valve\u2019s operating temperature and pressure due to the diaphragm\u2019s material and structure. It must also be replaced periodically since its mechanical properties degrade during usage.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe diaphragm isolates the non-wetted components (compressor, stem, and actuator) from the flowing media. Therefore, solids and viscous fluids are less likely to interfere with the operating mechanism of the diaphragm valve. This also protects the non-wetted components from corrosion. Conversely, the fluid in the pipeline will not be contaminated with the lubricant used in operating the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4>Material of Diaphragm Valve Diaphragm<\/h4>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Unlined or Rubber Lined Type<\/strong>\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>NR\/Natural Rubber<\/li>\r\n \t<li>NBR\/Nitrile\/Buna-N<\/li>\r\n \t<li>EPDM<\/li>\r\n \t<li>FKM\/Viton<\/li>\r\n \t<li>BUNA-N<\/li>\r\n \t<li>SI\/Silicone rubber<\/li>\r\n \t<li>Leather<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<strong>Fluorine Plastic Type<\/strong>\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>FEP, with EPDM backing<\/li>\r\n \t<li>PTFE, with EPDM backing<\/li>\r\n \t<li>PFA, with EPDM backing<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Diaphragm Valve Compressor<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe compressor is a disc that lies between the valve stem and the diaphragm. It supports the diaphragm valve and distributes the forces from the stem during linear movement. The compressor design is optimized to provide better flow throttling and control.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Diaphragm Valve Stem<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe stem is a vertical shaft connected to the compressor that exerts linear motion to move both compressor and diaphragm, thus operating the diaphragm valve. It transmits the motion exerted by the actuator. Diaphragm valves can either have piston- or threaded-type stems. As the name implies, piston-type valves are moved by a piston assembly inside the bonnet, with the valve stem likely acting as the piston rod. This type requires linear force exerted by fluid pressure. Threaded stem valves have a matching stem nut. This type requires torque to linearly move the stem, as well as lubrication for smooth motion.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe threaded stems of diaphragm valves can have a rising or non-rising mechanism:\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li><strong>Rising Stem<\/strong>: Rising stems or indicating stems extend their length up to the handwheel. As the handwheel is turned, the stem rises or descends to open or close the valve, respectively. Hence, it is easier to determine the extent to which the valve is opened by looking at the amount of stem exposed. However, rising stems take up more space than non-rising stems.<\/li>\r\n \t<li><strong>Non-Rising Stem:<\/strong> Non-rising stems or non-indicating stems are rotated to open or close the valve, but it does not cause the stem to move up or down. Non-rising stem valves are used in limited spaces, such as in underground piping systems.<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Advantages and Disadvantages of Diaphragm Valves<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:table {\"className\":\"is-style-stripes\"} -->\r\n<figure class=\"wp-block-table is-style-stripes\">\r\n<table>\r\n<tbody>\r\n<tr>\r\n<td><strong>Advantages<\/strong><\/td>\r\n<td><strong>Disadvantages<\/strong><\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Extremely clean<\/td>\r\n<td>Can only be used at moderate temperatures (-60 to 450\u00baF)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Leak proof seal<\/td>\r\n<td>Can only be used in moderate pressures (approximately 300psi)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Tight shut-off<\/td>\r\n<td>Cannot be used in multi-turn operations<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Easy maintenance<\/td>\r\n<td>No industry standard face-to-face dimensions<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Repairs can be made without interrupting the pipeline<\/td>\r\n<td>The body must be made of corrosive resistant material<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Reduce leakage to the environment<\/td>\r\n<td><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/figure>\r\n<!-- \/wp:table -->","parent":0,"count":2,"filter":"raw"},{"term_id":3205,"name":"Diaphragm Valve Manufacturers","slug":"diaphragm-valve-manufacturers","term_group":0,"term_taxonomy_id":3205,"taxonomy":"post_tag","description":"<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_e83080-b5\"} \/-->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nZECO Valves is a High-Quality Diaphragm Valves Manufacturer in China.

By dismantling the Bonnet from the Body, the whole Trim Assembly can be taken out for cleaning and maintenance while the Body will remain in the Pipeline. Hence the design allows maintenance to save time and energy. Its linear flow characteristics make it perfect for throttling or modulating operations. On\/off and control, automation is supplied with Pneumatic Actuators or Cylinders.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Diaphragm Valve Manufacturers<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Burkert Fluid Control Systems<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBurkert Fluid Control Systems is a global process supplier of high-quality customized fluid control systems and products, including diaphragm valves.
