Type VAIL/VA and VADDL/VA
Operation
Direct acting (differential control for the VADDL/VA), poppet type, line
mounting.
The valve allows pressure relief on delivery pipes to engines and cylinders.
When the actuator is braking, two check valves allow for anti cavitation on
delivery side.
Actuator close mount is recommended to assure a more rapid valve action.
