Kelite split body floating ball valves has below design characteristic,
Floating ball valves present a particular problem with the build up of static electricity around the ball. All Kelite ball valves have anti-static devices which provides contact between stem and ball, and stem and body to eliminate static electricity.
In the event of a fire the valve is required to make a downstream seal. Even after the disintegration of the RTFE seats, KELITE ball valves have an excellent metal to metal seal. Special attention has been paid to the mechanical strength and sealing efficiency of the central flanged joint in the valve body.
The PTFE gasket packing acts as a primary seal for the unibody ball valves. The secondary seal has been made out of flexible graphite, a material with extremely good resistance to fire conditions.
The combination of stem packingand o-rings guarantee zero emissions even at a low pressure. The primary seal is made out of flexible graphite, a material with extremely good resistance to fire conditions. The anti-blow out stem is inserted from inside the valve body.
