Fire safe, Anti-static...
Fire safe feature:
With the valve heated in a fire application, the non-metal material
parts such as seat sealing ring of PTFE, stem backseat gasket gland
packing and the sealing gasket between body and bonnet might
disintegrate or be damaged due to high temperature. We specially
designed structure of auxiliary metal to metal seal is provided to
effectively prevent both internal and external leakage of the
valve. As required by customers, Our ball valves with design can
meet the requirement of APl 607.
Ball valve can be designed to anti-static according to customers
requirement. It adopts a spring- piller device design, which can
for a path between ball and body or stem and body, for the static.
The static which produced by the friction of stem and ball is
leaded directly to the earth through above means, this guarantees
the safety and avoids fire and explosion
