The fire safe VALVE Instruction. Our company's fire safe VALVE designed and tested according to API 607 also complied with BS 6755 part2 specification. The VALVE'S soft seat made by Teflon in the fire Lip on the end connect comes in contact with the ball. That prevents leakage through the VALVE port.

The fire safe lip and groove are designed and used for all fire safe VALVE. The purpose is intended to permit full compression of the expanded graphite body seal and made alignment the body to the end.

The fire safe ball VALVE'S are all using more than 8 bolts which assembly to the body. And also The higher strength standard of the bolts. In the event of fire. These bolts can withstand inside pressure of the body. So can avoid leakage from body and end cap connection position.

The stem antistatic device and blowout proof. The fire safe stem outside diameter position is made by precision milling. That will extend the VALVE using life. will also the head of stem have installed spring and ball. It is antistatic device. The stem assembly into the body from within which is blowout proof.

The VALVE'S stem packing is special design. It can be adjustable by belleville washer that could be avoid the stem hole leakage. The stem packing was made by flexible Teflon and graphite gland packing. Also the graphite body seal would be compressed In the groove That will not be burn off.

After a Fire
The seats could be burn off. Than the inside of ball could be moved to downstream port and contact the metallic lip. Which is particularity milling. So that can be avoiding the leak age from downstream port.
