Pneumatic Gate Valve (API Spec 6A and SY/5127) The valve has safety valve and hydraulically derive, which is the main part in safety system in wellhead. By injecting a high-pressure air into the cylinder to reduce spring cylinder and open the valve. When in the risk, the actuator transmitted by the sensor to unload the pressure in cylinder in order to close the valve. Standard: API Spec 6A and SY/5127 Working principle: By using the hand wheel and cylinder to
