High Quality Pressure Compensated Hydraulic Automatic Water Flow Rate Control Valve

High Quality Pressure Compensated Hydraulic Automatic Water Flow Rate Control Valve Flow control valve is a multifunctional high-precision pilot-way control valve which is suitable for some of water distribution pipelines needing to control flow and pressure to maintain the predetermined flow and limit the excessive flow at a predetermined valve. It can also reduce high upstream pressure appropriately. As a result, even if the upstream pressure of the main valve changed, the downstream flow of the main valve is not affected. The valve changed the principles that conventional throttling valve reduces drainage area purely mechanically or by the pore plate and minimize energy loss in the throttling process by using relevant pilot valves. In case of emergency, flow control valve can completely cut off the flow and avoid loss. It has high sensitivity of control, safety, reliability, easy debugging and long service life.Meterial of main partsPart nameMeterialBodyGray iron, ductile iron, cast steelGateDuctile iron+EPDM or NBRAllen bolitsCarbonization processSealsNBR,EPDMBonnectGray iron,ductile iron,cast steelStemStainless steelO-ring sealsNBRThrust bearingsTin bronzeBoltCarbon steel,ally steelGlandDuctile iron,cast steelDust CoverNBRHand wheelMalleable iron  PN(MPa) Nominal pressure1.0-2.5DN(mm) Nominal diameter40-1600Medium temperature
