AAK Hydraulic Pressure Reducing/Relieving Valve of 3 Models, Equivalent to SUN H

Today, we launched a Hydraulic Pressure Reducing/Relieving Valve E-PRDB, which is equivalent to SUN standard part PRDB, including PRDB-LAN, PRDB-LBN, PRDB-LDN. This Direct acting concept provides highly reliable operation in contaminated systems, especially at dead headed conditions. Direct operated version offers superior dynamic response compared to equivalent pilot operated models.

This Direct-acting, pressure reducing/relieving valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). These valves incorporate a damped construction for stable operation allowing the use of high reduced pressure.

AAK E-PRDB hydraulic Pressure Reducing/Relieving Valve 2 Selling Points:
1. Internal leakage: 2 in³/min., benchmarking SUN Hydraulics
2. Service life is 2 times that of domestic peers
