Personnel shelter sealed valves are suitable for nominal pressure PN ≤ 0.05 MPa, operating temperature -30℃ to +40℃, relative humidity...

30-90% degree, on piping medium of air, serving as a one-way closed circuit mechanism. This valve mainly consists of the valve body,

The valve disc and transmission mechanism are composed. The opening and closing is achieved through the transmission mechanism, which uses a valve rod and a transmission lever to tension and relax the spring.

Utilizing the locking mechanism, the valve achieves the purpose of opening and closing. This valve is a unidirectional sealed valve and is not suitable for medium

Not suitable for regulation on a quality backflow pipeline. Electric shut-off valve consists of a motor reducer, electrical

The components consist of speed control and stroke control, etc., featuring the capability to separately self-lock both electric and manual operations, without the need for cutting.

In the event of an unexpected power outage while in electric mode, the handle can be used directly for operation; in manual mode, power can be suddenly applied.

Even in such cases, safety is ensured.
