Duplomatic CVM3-ST5/10N direct operated check valve
CVM3-ST5/10N is a Duplomatic MS direct operated check valve in NG6 modular sandwich construction. This execution has a check valve on line T, 5 bar cracking pressure and NBR seals. It mounts in an ISO 4401-03-02-0-05 valve stack without external interconnecting pipes.
The spring-loaded check element prevents reverse oil flow in the selected line and helps prevent line self-emptying. The selected 5 bar cracking pressure is the differential pressure required to start opening the check element. It must be added to the flow-related pressure drop shown in the catalogue. This valve opens directly from differential pressure and has no hydraulic pilot release.
This ST execution controls the tank line. Account for the resulting return-line backpressure when selecting the valve and associated stack components.
Maximum operating pressure is 350 bar. Maximum flow is 50 l/min in controlled lines and 75 l/min in free lines. Use HL or HM mineral hydraulic oils with the specified NBR seals and maintain fluid cleanliness to ISO 4406:1999 class 20/18/15. The recommended oil viscosity is 25 cSt.
