Frequently Asked Questions

As the name suggests, Normally Open valves allow air to pass when they are not energized (or actuated). Normally Closed valves must be actuated to allow air to pass.
We have passed 1 million times of product quality test, and obtained the certificate.
The air actuator does not have a manual override, but a manual override is provided with optional direct mount solenoid valves.
See product specifications. Generally, smaller valves less than 2 inch pipe size, cycle in about one second. Larger valves up to 6 inch pipe, cycle in about 1.5 seconds. A cycle is per 90° rotation
