KHD-31 KHD-35 MODEL

3-piece threaded / butt weld ball valves – soft seated

Three-piece ball valves composed of 3 separate pieces held together by bolts.
A three piece ball valve is preferred wherever regular cleaning is required.
The ball valve ends can remain threaded into the pipe, while the center section can be removed.
A butt weld ball valve contains a butt weld-sized connection for inlet and outlet connection.
The valve with butt welding end connection ensures no accidental leakage.
Threaded ball valves contain internal and external threads to facilitate inlet and outlet connections.
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-31 BALL VALVE – No mounting pad

These valves are without an ISO mounting interface. This means that you need a bracket and drive dog to mount the actuator to the valve.

KHD-35 BALL VALVE – ISO direct-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.
