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

30-90% degree, on piping with air as the medium, it acts as a unidirectional closed circuit mechanism. This valve primarily consists of the valve body,

Valves and transmission devices, etc., are composed. The opening and closing are achieved by the transmission device through the valve rod, utilizing a transmission lever to tension and release the spring.

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

Not suitable for regulating purposes on a reverse flow pipeline. Electrically sealed valve consists of a motor reducer, electrical...

The assembly is composed of components such as actuator control and stroke control, featuring the capability of being separately locked either electrically or manually without the need for 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 can be suddenly applied.

In such cases, safety is also ensured.
