Second, the working principle of: Gas valve open by spring force the valve is closed, air to close valve by the spring force the valve is open, the two valves are 0.49MPa compressed air as power, before the valve is equipped with a two four-way valve, the action principle: 1. Gas valve open: compressed air through the air filter, solenoid valve into the bottom of the cylinder, push the piston, compression spring, so putting on the move, open the valve. 2. Air to close valve: compressed air through the air filter, solenoid valve into the cylinder at the top, push the piston, compression spring, so putting down, the valve closed. Third, pay attention: 1. Valve must be installed vertically, the medium flow direction of the arrow at the valve. 2. Piston cylinder must be cleared of clean dirt never promised, so as not to affect the piston, the lower work. Pneumatic quick start valve (air to close type) Quick opening and closing valves
