Product details

Close the emergency shut-off valve remotely through the direct channel

四代切断阀-1

Product Features

1. Retaining the inherent and typical performance characteristics of the third-generation remote control emergency shut-off valve, which can achieve valve closure due to real-time overpressure and underpressure in the local pipeline;

2. Adopting a new low torque straight channel ball valve structure with low operating torque;

3. The straight through structure is easy to clean and can effectively prevent ice blockage.

fitScope of use

The emergency shut-off valve for remote closure of direct passages has a wide range of applications in fields such as oil and gas, chemical, metallurgical, and power. It can ensure the safe operation of fluid pipelines in various application fields.

Specification parameters

Maximum set pressure range for valve overpressure and underpressure:

Under voltage cut-off setting value (MPa) Overpressure cut-off setting value (MPa)
0.1-5Mpa 5-25Mpa

Power supply used for emergency shut-off valve: 12V 24V

Emergency response time: The shutdown time is less than 2 seconds, and the response time for overvoltage and undervoltage shutdown is less than 2 seconds.
