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.
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 mmø 3.35″ and ø 5.24″, 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.
How it works
The valve consists of two valve body halves, valve disc, bushings for the disc stem and seal ring. The valve is assembled by means of screws and nuts.
The standard Tri-Clover LKB UltraPure butterfly valve range is designed either for automatic or manual operation.
The automated LKB UltraPure butterfly valve is controlled from remote location by means of compressed air using a pneumatic actuator. The actuator controls the axial movement of a piston, which rotates the shaft 90°. The torque exerted by the actuator increases when the valve disc contacts the valve sealing ring, to ensure effective closing. The actuator is available in three standard versions: normally closed (NC), normally open (NO) and air/air activated (A/A).
The Tri-Clover LKB UltraPure butterfly valve is controlled manually by means of a handle. The handle mechanically locks the valve in its open or closed position. A two-position, four-position, regulating 90° or lockable multi-position handle is available. The handle is fitted on to the valve by means of a cap/block system and a screw and can be supplied with either welding or clamp connections.
