Duplex Spring Safety Valve

The safety valve is composed of two safety valves of the same model and specification assembled at a Type Y connector, of which the nominal diameter means the inlet diameter of Type Y connector.

Sealed Spring Low Lift High-pressure Safety Valve

Carbon steel valve is used for equipment or pipelines containing such medium as air, petroleum gas, and liquid; stainless steel valve is used at equipment or pipelines containing corrosive medium, serving as overpressure protection device.

Sealed Spring Low Lift Safety Valve

Carbon steel valve is used for equipment or pipelines containing such medium as air, petroleum gas, and liquid; stainless steel valve is used at equipment or pipelines containing corrosive medium, serving as overpressure protection device.

Spring Low Lift External Thread Safety Valve

Carbon steel valve is used for equipment or pipelines containing such medium as air, petroleum gas, and liquid; stainless steel valve is used at equipment or pipelines containing corrosive medium, serving as overpressure protection device.

Safety Valve for High-temperature Steam

It´s used for all kinds of steam containers and pipelines as overpressure protection device.

Series Safety Valve for Refrigerating Machine

Safety valve for refrigerating machine is used for refrigerating equipment as overpressure protection device; when the operating pressure of equipment rises beyond the allowable value, the valve can open automatically and discharge a rated amount of medium according to the equipment´s operating requirements to prevent equipment pressure from further rising so as to protect the whole system; SFA-22C150T and SFA-22C300T series safety valves made by SVF are overpressure protection device matched with condenser and evaporator of refrigerating machine, and product test and performance meet the requirements of relevant standards as American ANSI B16.34, ANSI/ASHRAE15-78 and Chinese GB12241-12243;

Built-in type Safety Valve for Tank Car

SFNA-42B25C1 type safety valve adopts built-in structure, which occupies a small space, so it´s especially applicable to tank car and similar equipment as overpressure protection device.
The working medium shall enter the product below the valve clack, and excess medium is directly discharged to the space. Spring is installed in the inner cavity of valve clack, and the valve has compact structure, small volume, and light weight. The opening pressure is adjusted by turning the adjusting nut, and it´s very easy to use and install.

DIN Series Safety Valve

Carbon steel valve is used for equipment or pipelines containing such medium as air, petroleum gas, and liquid; stainless steel valve is used at equipment or pipelines containing corrosive medium, serving as overpressure protection device.

ASME Ⅰ Series Safety Valve

It´s used at power boiler, once-through boiler, reheater, superheater, and other steam equipment as overpressure protection device. It adopts double adjusting rings and back pressure jacket to adjust reseating pressure to achieve tiny blowdown, and elastic valve clack can ensure sealing performance at high temperature.
