03. Features
001. The stem - diaphragm assembly with dual lead action through top and seat rings provides long life and reliability, 
002. All cast iron parts are coated with powder epoxy resin to resist corrosion. 
003. During maintenance, the main valve can be repaired directly on line without disconnecting from the pipeline. 
004. The linear flow of valve body is convenient to obtain better control characteristics and lower head loss. 
005. Ductile iron has high strength and light weight
006. Reinforced nylon diaphragm, die layer thickness uniform strength, good precision, durable. 
007. Internal use of stainless steel seat, guide platen and shaft, durable. 
008. Good closing effect, safe zero crown leakage. 
009. Hydraulic operation does not need external power, it can be matched with different guide valves and accessories as opening and closing or adjusting water level, pressure and flow. 
010. There is a lifting ring attached above DN150 for lifting operation. 
Feature description: 
001. The pressure reducing valve device is in the system pipeline. When the outlet pressure exceeds the setting system of the wizard valve, the main valve will be automatically closed by the wizard valve, and the main valve will be automatically opened when the pressure is lower than the set value. 
002. The pressure change at the outlet is not changed by the pressure change at the upstream inlet, nor by the water quantity at the downstream outlet. 
003. The final outlet pressure value reaches the equilibrium, that is, the pressure setting value.

07. Operating principle
Relief pilot valve's work is based on the spring down on began and the force of the disc and close the disc forces on diaphragm upward on the basis of mutual balance, when the main valve back-end water, pilot valve spring pressure is greater than the effect on water pressure of the bottom of pilot valve diaphragm, pilot valve began to qi, the main valve cavity drainage outward, the main valve to play me alone, when the main valve back-end without water, the back-end pressure increases, the pilot valve diaphragm upward push, to close the pilot valve, which makes the main valve closed, the back-end pressure stable in a fixed value, and the main valve back-end water is different, make the effects on different water pressure of the bottom of pilot valve diaphragm, pilot valve began to change, Thus, the size of the main valve opening can be controlled to keep the pressure at the back end at the set value. The pressure set at the back of the valve can be adjusted by the adjusting screw on the pressure relief guide valve. 

08. Applications
Widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC and general industry.
