Ball Valve – KHD-TB

Customizing tank bottom ball valves are well-suited for general purpose tank or vessel applications.

The tank bottom ball valve is equipped with a special flange connection for welding to the bottom of a tank or vessel.
End profile and radius have an effective gravity discharge effect.
Smooth conical holes and ultra-close balls in the tank prevent the media from piling up at the valve entrance and ensure smooth discharge.

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.

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-TB 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.
