Cartridge Pilot operated Check Valves type CRH and RHC<br />
Pilot operated check valves are used in hydraulic circuits<br />
where the directional control valves exhibit normal spool<br />
leakage. They can also be used as hydraulically operated<br />
drain valves or as “idle circulation” valves.<br />
Q max: 80 l/min (CRH)<br />
200 l/min (RHC)<br />
P max: 500 bar<br />
The type CRH valves are pilot operated cartridge type<br />
valves and the type RHC valves are designed as screw-in<br />
valves. The RHC valves are available with a decompression<br />
(pre-release) function for high pressure and high flow<br />
applications. The mounting ports are of a simple, easilymachined<br />
design. Ask for machining details.<br />

Cartridge & In-Line Check Valves, type RK<br />
Check valves are used to block flow in one direction and<br />
permit free flow in the opposite direction. The RK check<br />
valve is a spring-loaded, ball seated type which, by<br />
design, is tolerant of contamination.<br />
The mounting ports are easily machined for the screw-in<br />
RK type. Housings for in-line installation are available on<br />
request or easily manufactured. Installation tools are also<br />
available to ensure correct assembly of the insert.<br />
