Ball Valve – 2pc flange (soft seat)
Ball Valve – KHD-11, KHD-15
One-piece ball valves are made out of one body piece.
This means that the valve cannot be disassembled for cleaning.
However, there is a low risk of leakage because there are no body joints.
The advantage is that the valve will be low cost and robust.
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-11 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-15 ball valve
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.
