Double cross line valve for cylinder protection – in line installation


DCA direct acting relief valves are meant for protecting the hydraulic cylinder from sudden pressure peaks caused by accidental events.

Description

Details

In applications where the hydraulic actuator can suffer shocks or other accidental events with consequent sudden pressure peaks, the DCA shockproof valves limit the damages to the actuator itself and to the hydraulic system. A typical application of these valves is on the extensions of a telescopic cylinder or on hydraulic motors that drive rotating parts. Depending on the chosen size, the DCA valves can work with flow rates up to 20 lpm (5.3 gpm) and operating pressures up to 350 bar (5075 PSI). The BSPP-GAS threaded ports make it possible to install them in line. The body and other external components are made of steel and protected from corrosion by galvanizing.
