2-PC Ball Valves
BALL VALVE – KH
Segment ball salves are also known as V-port ball valves.
The ball valve core is designed with a special V shape notch.
This contributes to strong shear force and precise flow control.
Common are wafer type segmented ball valves and flanged type segmented ball valves.
In general, soft seats are made of thermoplastic materials such as PTFE.
However, soft seats are not recommended for dirty or abrasive process fluids.
Soft seats can break under these conditions, causing leaks in the valve.
In general, metal seats incorporate a metal-to-metal seal between the seats and ball of the valve assembly.
In general practice, metal seats can stand up to extreme flashing, hydraulic shock, abrasive process fluid, and high temperatures.
They are also ideal for high erosion or corrosion applications.
