CRYOGENIC EMERGENCY CUT OFF VALVE MANUFACTURERS IN INDIA
Speciality Valve is a prominent Cryogenic emergency cut off valve manufacturers in India that specializes in supplying safety-critical valve solutions for low-temperature plants. Specialty Valves cryogenic emergency cut off valves are designed to provide immediate shut-off of dangerous cryogenic fluids such as LNG, LOX, and nitrogen during emergencies with ultimate safety.
Why Cryogenic Emergency Cut Off Valves Are Needed?
Safety is of the highest concern in cryogenic systems. The valves are mounted to shut off the flow immediately in the case of pipeline failure, fire, equipment malfunction, or system failure. The immediate shutoff safeguards downstream equipment, people, and the plant from possible exposure to cryogenic fluid leak or over-flow.
Key Parts of Cryogenic Emergency Cut Off Valve:
1) Long Bonnet: Reduces thermal stress on valve internals
2) Body Material: Cryogenic-grade stainless steel
3) Actuator: Pneumatic, hydraulic, or electric (failsafe)
4) Quick-Closing Mechanism: Actuated by emergency signal or loss of pressure
5) Seal & Seat Assembly: Structured to provide zero leakage during sub-zero temperatures
How It Works?
The cryogenic emergency cut-off valve functions via an actuator initiated by emergency signals or system failures. When the actuator is initiated, it rapidly closes the valve, cutting flow immediately. The extended bonnet precludes ice formation around the packing region, allowing operations to be easy in cryogenic temperatures.
Advantages of Cryogenic Emergency Cut Off Valve:
1) Emergency fast shut-off
2) Leak-free sealing even at -196°C
3) Temperature and corrosion resistant
4) Automatic or manual reset option
5) Improves system reliability and safety
Functions of Cryogenic Emergency Cut Off Valve:
1) Emergency isolation of cryogenic lines
