Duplomatic CVM3-SA3/10N direct operated check valve
CVM3-SA3/10N is a Duplomatic MS direct operated check valve in NG6 modular sandwich construction. This execution has a check valve on line A, 3 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 3 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.
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.
