YPR-2W Type - Primary Pressure Regulating Valve for Water 10K 

This is a type of relief valve and self-operating regulating valve that discharges excessive pressure resulting from load fluctuations and maintains a constant pressure level in instruments or pipelines. In case of continuous pump operation, changes are
made according to fluctuations in the discharge pressure load. 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

• Easy to handle: small size and light weight.
• Two ways to install: horizontally or vertically.
• Stable operations: no such issues as hunching or vibration.
• Use of a disc made of special materials inside the valve: No water leakage when the valve is opened and closed.
• Piston-type balance structure: almost no change in the opening pressure resulting from back pressure fluctuations.
• The pressure tank can be used as a relief valve in a pipeline.
