Product Description
Pressure Reducing piston Valve dn5001.DescriptionPressure Reducing Valve automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. The valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a re-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.02.Main parts&material| No. | Part | Material | China stardard |

001.Stem diaphragm assembly with double 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.High strength and light weight of ball iron valve body.
006.Reinforced nylon membrane, die layer thickness uniform strength, good precision, durable.
007.Internal use of stainless steel seat, guide platen and shaft, durable.
008.Good closing effect and zero leakage safety.
009.Hydraulic operation does not need external power, can be matched with the need to match different guide valves and accessories as opening and closing or adjust the water level, pressure and flow.
Feature description:
001.When the water level of the pool reaches full.The main valve is closed by means of a control ball valve.
002.When the water level of the pool decreases, the control ball valve begins to fill, then the main valve is opened through the control ball valve.
003.Control the ball according to the requirements of the site, directly put the whole set of valve devices together, directly open and close the main valve or separately install the control ball valve at the full water level to achieve the purpose of remote control.
