Concept

LKB UltraPure is an automatic or manually operated butterfly valve for

on/off duties. The UltraPure execution is designed and documented to

meet the demand in industries like BioPharm and Personal Care.

Working principles

LKB UltraPure is either remote controlled by means of an air-actuator

or manually by means of a handle.

The actuator is designed so that an axial movement of a piston is

transformed into a 90° rotation of a shaft. The torque of the actuator is

increased when the valve disc contacts the seal of the valve.

The air-actuator comes in three standard versions, normally closed

(NC), normally open (NO) and air/air activated (A/A).

Two actuator sizes, ø85 mm and ø133 mm, cover all valve sizes and

are available in two versions, LKLA and LKLA-T (T for mounting of

indication unit on actuator).

The handle for manual operation mechanically locks the valve in its

open or closed position.

Handles are available in 2 positions, 4 positions, regulating 90° and

lockable multi-position.

The valve can be supplied with either welding or clamp connections.
