Ball Valve – KHD-SGW

Lightweight yet rugged segment ball valves are suitable in harsh environment for both on-off and control applications. Widely used in pulp and paper, chemical, and petrochemical services.

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, 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.

KHD-SGF-W 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.
