Airlock valve
Model: TOP-400SN / TOP-400SG/ TOP-400DN / TOP-400SG / TOP-405SN / TOP-405SG/ TOP-405DN / TOP-405SG
The air lock valve TOP-400/405 series products use the main air source as the signal pressure. When the signal pressure is lower than the set pressure of the air lock valve, it will cut off the air circuit inside the air lock valve and prevent the air flow. The main purpose is to install it on the control valve. When the main gas source pressure of the factory drops below the set pressure due to power failure, leakage, etc., the gas path from the positioner to the actuator will be automatically closed to ensure the current valve position opening.
