Fluid circulation valve
ACCESSORIES FOR TXV PUMPS
FCV
The fluid circulation valve (FCV) is designed for applications where the hydraulic variable
displacement pump is used in standby mode for a long period of time, for example engine
PTO.
This valve allows oil circulation in the pump, which protects the pump from overheating.
