[JSV-BF31] Safety Valve with Balanced Bellows Type Old Model: SSRF-B

This valve is generally used for pressure vessels, tracing equipments and pipes at the petroleum, gas and chemical plant. This is especially used on the place which is influenced by a back pressure of outlet side, the place which is not allowed fluid’s flowing to outside of safety valve and the place which has some worrying about distortion or corrosion of spring by corrosiveness of fluid or temperature.

详细描述

■ FEATURES

1. This valve is designed and produced based on the size of safety valve for steam and gas (KS B 6276).
2. Since this valve adapts bellows of balance structure, its structure is not influenced by a back pressure.
3. The structure does not allow outflow of the fluid to safety valve’s body, thus, this valve would use for poison gas or flammable gas.

4. Since this valve is a lift type structure, it could obtain larger capacity than the safety valve with a full bore type.

5. The main materials of inside is made of STS316, so this valve has an excellent corrosion resistance.
