Ductile Iron Grooved Pilot Operated Pressure Reducing Valve G200X-16Q

G200X trench pilot operated pressure reducing valve is a pressure reducing valve in hydraulic control valve, it is a kind of function type valve which utilizes the medium's own energy to regulate and control the pipeline pressure. This valve is designed for high-rise buildings, by adjusting the pressure reducing pilot valve, you can adjust the outlet pressure of the main valve. Outlet pressure does not change due to changes in inlet pressure, inlet flow, safe and reliable outlet pressure to maintain the set value, and can be adjusted according to the need to set the value to achieve the purpose of pressure reduction. The valve pressure reduction, stable performance, safe and reliable, easy to install, long service life, mainly used to solve the high-rise building water, fire water system, the requirements of the flow rate, sensitivity and other occasions, instead of intermediate tank, saving the cost of building intermediate tanks, expanding the use of the building area. It is widely used in high-rise buildings, industrial water supply, fire-fighting water supply and domestic water pipe network system and urban water supply engineering field.

Working Principle

When the valve is fed from the inlet side, water flows through the needle valve into the main valve control chamber and outlet pressure is applied to the pilot valve through the conduit. When the outlet pressure is higher than the pilot valve spring setting, the pilot valve closes. The control chamber stops draining, at which time the pressure in the main valve control chamber rises and closes the main valve, and the outlet pressure no longer rises. When the valve outlet pressure drops to the pilot valve spring setting pressure, the pilot valve opens and the control chamber drains downstream. As the pilot valve system drains more water than the needle valve inlet, the pressure in the main valve control chamber drops. The inlet pressure causes the main valve to open. In the steady state, the control chamber inlet and discharge are the same, the main valve opening is constant, and the outlet pressure is stable.

Product Features

G200X trench pilot operated pressure reducing valve consists of main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control receiver system. When used, it can automatically maintain stable outlet pressure when the outlet pressure is adjusted. This product uses the pilot valve to control itself, without other devices and energy, easy maintenance, high accuracy of pressure control, small influence by the inlet pressure and flow, reliable pressure reduction and stabilization.
