property=\"og:description\" content=\"What is a Pressure Reducing Valve?  A Pressure Reducing Valve is a self-operating valve used to control excess pressure to give a constant reduced pressure to a system. The pressure reduction regulator is another name for this valve. The primary function of pressure-reducing valves is to convert increased incoming pressure into lower outgoing pressure. They are widely utilized in the water, steam, and oil and gas sectors. So, Pressure Reducing Valve manufacturers define the valve as a self-acting automated control valve that reduces a greater uncontrolled intake pressure to a constant, lowered output pressure independent of upstream water pressure variations. We will learn about the working, different types, uses, and benefits of pressure-reducing valves in this article.  How does a Pressure Reducing Valve work?  When it does this under both flow and no-flow conditions, the type of control is known as \u2018drop tight\u2019. ZECO pressure reducing valves use a balanced spring and diaphragm to control the downstream pressure. This \u2018drop tight\u2019 feature is one of the most important criteria for any pressure reducing valves, as this stops the pressure from \u2018creeping\u2019 \u2013 a term which is used when an increase in the downstream pressure occurs under no flow conditions. A valve which will allow this \u2018creep\u2019 cannot be known as \u2018drop tight\u2019 or in fact a true pressure reducing valve, as it will eventually allow the pressure to creep up to equal the upstream pressure, which can cause significant problems and essentially negates the point of using a pressure reducing valve in the first place.  The diaphragm effectively separates all of the water contact parts and the pressure from the water supply away from the control spring and associated mechanism. The body is then protected from debris by the use of a stainless-steel strainer.  Under no flow conditions the downstream pressure puts back-pressure on the seat and diaphragm of the valve, which in turn overcomes the spring pressure. This means the seat moves up, forcing it to seal against the diaphragm, therefore not allowing the downstream pressure to increase.  Under flow conditions the back pressure against the seat is reduced thus allowing the seat to open and water to flow through the valve.  Advantages of Pressure Reducing Valves  Direct acting pressure reducing valve is suitable for general liquids and gases. WRAS &amp; ACS Certifications for Drinking Water and Beverage application. Suitable for process automation control and many general purpose applications. Convenient in-style mounts either horizontally or vertically. Wide range capacity to handle local water supply pressure and adjust to specific pump specifications. Adjusting nut allows easy calibrated pressure adjustment. Stainless Steel 316 lower body and upper body construction for durability and compatibility. The balanced piston design provides a constant outlet pressure even when the inlet pressure is unstable. The supplied pressure gauge indicates the outlet pressure. Easy maintenance, maintenance kits are available upon request.
