200X Leader Type Pump Control Valve Pressure Reducing Valve

200X Leader Type Pressure-Reducing Valve

1. PRODUCT PROFILE

200 x pilot operated relief valve for high-level, high-rise building design, is to address the domestic water supply in high-rise constructions, fire water system, large flow, high sensitivity occasions ideal products. Its performance is superior, replace the intermediate water tank completely, save the cost of the cistern and enlarge the area of the building.

2. Performance characteristics

· The structure is novel and reasonable and reasonable use of hydraulic principle

· The disc is fast open, no water hammer blow (closing time adjustable)

· Good sealing and long service life

· The work is steady and reliable and the traffic is high

· The accuracy of the stabilization is high and the range is wide

· The installation of maintenance is convenient

3. WORKING PRINCIPLE

· When the valve feeds water from the inlet, the water flows through the needle valve into the main valve control room, and the outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the guide valve spring setting value, the pilot valve is closed. When the control room stops draining, the pressure in the main valve control room rises and the main valve is closed, and the outlet pressure is no longer increased.

· When the valve outlet pressure drops to the setting pressure of the pilot valve spring, the pilot valve opens and the control room drains downstream. Because the displacement of the pilot valve system is larger than that of the needle valve, the pressure of the main valve control chamber decreases. The inlet pressure opens the main valve. Under steady state, the inlet and drainage of the control room are the same, the opening of the main valve is constant, and the outlet pressure is stable.
