AAK Hydraulic Pressure Reducing/Relieving Valve Equivalent to SUN PRDB

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

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

Technical parameters of AAK E-PRDB Hydraulic Pressure Reducing/Relieving
Max. Operating Pressure: 350 bar (5000 psi)
Flow: 10 gpm (40L/min)
Internal Leakage: 2 in³/min.
Temperature: - 35 to 120 °C (with Standard Buna N seals)
