In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n\u2022 \u0394P Control\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side.
