2 port slip - in model : cv · the cartridge valves with model cv are used to control oil pressure...
TRANSCRIPT
The cartridge valves with model CV are used to control oil pressure flow rate or direction and are designed for insertion into cavities machined as per ISO 7368. These cartridges are available in two area ratios , four cracking pressures and seven poppet styles. The covers are available for different functions like directional control, pressure control, unloading, flow control etc.
