ZJY46H piston type pressure reducing valve position in water use stainless steel or hard seal structure using soft seal structure can be reduced static pressure.

here's why:

after the pressure reducing Industrial Valves valve closed a valve, pipe flow velocity is zero, we pressure reducing valve disc, namely the throttling cone will quickly shut down.

1, we as a manufacturer, can according to the requirements of customers special design on sealing surface, hard seal design in theory can be achieved without leakage flow of 0.

2. If after the pressure reducing valve in pipe is frequently the phenomenon of the small flow of water, Such as all kinds of water) , so even if there is a slight bit leakage, can also will rise after valve pressure discharge in a timely manner. Use durable degrees higher, stronger cavitation resistance ability hard seal structure of the pressure reducing valve is superior to the soft sealing structure of the pressure reducing valve.

at the same time use the soft seal ZJY46H piston type pressure reducing valve, sealing face of the soft sealing material to ensure valve in front of the high pressure water from leaking into the valve after the pipe, valve pipe remains low.

but soft sealing pressure reducing valve valve sealing surface material is nitrile butadiene rubber, relative to the stainless steel hard seal disc, insufficient in cavitation resistance and durability. The material of metal sealing drip leakage is allowed, pressure reducing valve shut down for a short period of time will not cause great influence to Industrial Valves after pressure.

although ZJY46H combined type pressure reducing valve can reduce static pressure, but it is not recommended to put pressure reducing valve used as disconnection valve, it is recommended to have conditions to take truncation gate valves and butterfly valves.
