KHD-SGF MODEL

Flange wafer type V segment ball valve – soft seated

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.
Flanged ball valves provide effective control of oil and gas operations.
Their characteristic feature is the flanged ends that are bolted to the oil and gas piping.
A wafer-type ball valve is defined as a flangeless design.
Wafer-type ball valves feature a hinged, flap-like disk (the wafer) that is used to allow and restrict liquid flow.
In general, soft seats are made of thermoplastic materials such as PTFE.
They are ideal for applications where chemical compatibility is important and where the tightest possible seal is essential.
However, soft seats are not recommended for dirty or abrasive process fluids.
Soft seats can break under these conditions, causing leaks in the valve.

KHD-SGF BALL VALVE – ISO direct-mount / ISO regular-mount

A direct mounting flange according to ISO 5211 is standard for these ball valves.
This feature allows an actuator to be mounted without the need for a mounting bracket and drive adapter.
This results in a significant cost reduction, a compact automated unit, and a higher level of safety for operators.
The ISO regular-mounting pad accepts direct mounting of pneumatic and electric actuators.
ISO 5211 is a European standard that specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.
