Rexroth Pilot-Operated Check Valve NG30 SV 30 PA 3-42

Description

This is a robust pilot-operated check valve, model SV 30 PA 3-42, manufactured by Bosch Rexroth. Designed as a sandwich plate valve with a nominal size of NG30, it is engineered for reliable performance in demanding hydraulic applications. The valve allows free flow in one direction and blocks flow in the opposite direction until a pilot pressure signal opens the valve. This component is in used condition but is built to last, providing a cost-effective solution for your machinery.

FAQ

The SV 30 series valves are typically rated for a maximum operating pressure of 315 bar (4568 PSI), but it is crucial to consult the specific datasheet for the 3-42 series for exact specifications.

These valves are generally compatible with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids, like synthetic esters, you must verify the compatibility of the installed seals.

Installation involves placing the valve between a directional valve and a subplate. Ensure all surfaces are clean and O-rings are correctly seated. Use the correct length and grade of bolts, torqued to the manufacturer's specification, to prevent leaks and ensure proper function.
