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

30% to 90% degree, used on piping with air as the medium, acting as a unidirectional 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 the 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 mediums

Not suitable for adjustment on a reverse flow pipeline. Electrically sealed valve consists of an electric motor reducer, electrical...

The assembly consists of components such as drive control and stroke control, featuring the ability to be separately locked in both electric and manual modes without requiring cutting.

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

Even in such cases, safety is guaranteed.
