DESCRIPTION
Blocking Element is a block with a piston which operates with a help of a pilot signal received from the On-Off Solenoid Valve. It has a spring on one side to bring the piston to home position, when the pilot signal is released. It also has a manual lever to operate the valve when the pilot signal is not available in emergencies.
FUNCTION
The blocking Element is used to block the flow from the servo valve to actuators and also from the actuator to servo valve
APPLICATION
Blocking Element is used in HPBP System wherever servo valve is used.
