The Y42X- seawater pressure reducing valve consists of two parts: the main valve and the pilot valve. The main valve is mainly composed of parts such as the valve seat, main valve disc, piston and spring. The pilot valve is mainly composed of parts such as the valve seat, valve disc, diaphragm, spring and regulating spring. The outlet pressure is set by adjusting the pressure of the regulating spring. The changes in the outlet pressure are sensed by the diaphragm. The opening and closing of the pilot valve drives the piston to adjust the size of the flow area at the throttling part of the main valve, thereby achieving the function of pressure reduction and pressure stabilization.
It is mainly used in oxygen or seawater pipelines to play a role in reducing and stabilizing pressure.

Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’ is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
