Cross-Over Relief cartridge valves provide pressure protection to hydraulic motors, cylinders and rotary actuators up to 120 lpm (32 gpm) and 350 bar (5000 psi). Available in single or dual cartridge, in-line, manifold, or motor mount configurations.

Crossover Relief Valves Typical application for the RVC valve is in a series circuit where a load on motor #2 causes back pressure on motor #1 and relief valve #1. Vent in port 2 of RV 1 allows spring to maintain proper load on motor #1 even though back pressure is present.

Provides crossover relief protection for reversible hydraulic motors or can be used as a cushion valve for a double acting cylinder. Used to stop/minimize surges, shocks and overloads on hydraulic circuits.

Dual Cross-Over Relief Valve with Motor Mount. This valve provides overload and shock protection for small gerotor motors with a manifold mounting pattern, such as the Parker TB and TE series. Close coupling the valve to the motor provides ideal protection and eliminates plumbing. For additional information see Technical Tips on pages PC1-PC6.

between the two relief valve settings. General Description Dual Cross-Over Relief Valve. For additional information see Technical Tips on pages PC1-PC6. Features s Fast acting differential area reliefs for high flow capacity s Spherical poppets for low leakage s Internal mechanical stop limits poppet travel eliminating spring solidification

Parker’s DXV Crossover Relief Valve is a fast, direct acting design that provides pressure overload protection for an actuator where the relieved flow is 10 GPM or less.

The dual relief is of the cross over type, and exhausted oil is transferred to the other line (from V1 into V2 and vice-versa), without the necessity of a separate tank line: this feature also prevents cavitation when used in conjunction with closed centre directional valve.

A few of these valves are designed to be line mounted on the 2 main hoses, but many of them are studied to match the port patterns of commercially available hydraulic motors and they can be flanged onto the motor directly simplifying plumbing and saving space.
