YPR-41W Type Primary Pressure Regulating Valve for Water 20K 

This is a type of relief valve and regulating valve that discharges excessive pressure resulting from load fluctuations and maintains a constant pressure level in instruments or pipelines. It is possible to install this product as a primary pressure regulating valve in
the bypass circuit to relieve excessive pressure, and to adjust the discharge pressure to remain constant.
 

Features

• A constant pressure level with only a single adjustment.
• Stable operations: no such issues as hunching or vibration.
• Piston-type balance structure: minimal change in the opening pressure resulting from back pressure fluctuations.
• Upper part dissembles in one-way: allows for internal inspection and maintenance.
• Use of a disc made of special materials inside the valve: No water leakage when the valve is opened and closed.
