200X-10Q/16Q pilot operated pressure reducing valve

Category Relief Valve

200X-10Q/16Q pilot operated pressure reducing valve consists of a main valve, pilot valve, needle valve, ball valve, and pressure gauge valve, The needle valve, ball valve, and pressure gauge are composed of a hydraulic control receiver system. The structure form is a T-type diaphragm drive.

Nominal Dimension	1.0/1.6MPa
Applicable Temperature	0~80°C
Applicable Medium	Water

Process Description

Ductile cast iron is used as material to form the basic shape of the valve. The valve then goes through the process of Casting, shot blasting treatment, stress-relief annealing, machining, powder coating, assembly, pressure testing, packaging, and storage. With a final inspection, the valve will be packaged and sent out.

Features

1. It can balance and regulate the pressure of network water supply pipeline, energy saving and consumption reduction.
2. Using its own pipeline pressure to regulate and control the pressure after the valve, reducing and stabilizing pressure reliably.
3. The outlet pressure after the valve does not change with the change of inlet pressure and flow rate, and it can automatically maintain the outlet pressure on the adjusted stop.
4. The valve control sensitivity is high, safe and reliable, easy to debug, long service life.
5. The valve should be equipped with a filter, and an exhaust valve should be installed at the high point of the pipe section after the valve.
6. Suitable for life, fire, high-rise buildings and other water supply network systems and urban water supply projects and other industrial water supply systems.
