SSV-A400HseriesCylinder driven axial flow safety shut-off valveWidely used in the field of safety, this series of valves has the following characteristics:
1. 1.Axial flow, high flow capacity and reduced pressure
2. 2.Full pressure balanced valve core
3. 3.Lightweight moving parts
4. 4. short stroke
5. 5.Cylinder driven axial flow safety shut-off valveThe design is fundamentally very suitable for security fields that require quick shutdown. Has fast cut-off time,≤36”All valves can be used2Cut off in seconds,≤12”of Valves can be used1Cut off within seconds.
6. 6.The automatic protection of the main seal in the fully open position of the valve minimizes the risk of erosion and damage from high-speed media. In addition, the main seal does not come into contact with other components during its travel.
7. 7.A linear piston type hydraulic spring closing self driving actuator that does not require any external power source, with high safety and reliability through multi-layer spring closing action, ensures the safety and reliability of valve action, and is energy-saving and environmentally friendly.
1、 The entire security system is typicalHIPPSThe system consists of the following three parts:
1. 1.The final executing component is the safety shut-off valve
2. 2.The detection instrument is a pressure transmitter
3. 3.plc
