early)
- High pressure
- High temperature

- Change rubber grade
- Change the operation conditions
- Difficult to open/close
- Damage of disc connection (high
torque)
Incorrect seal ring (swelling) Replace by a seal ring of a different rubber
grade
Difficult to open/close - 90° displacement of the actuator
- Incorrect actuator function (NC,NO)
- Worn actuator bearings
- Dirt penetration into the actuator
- Fit correctly (see 3.4 Fitting

valve (optional extras))
- ChangefromNCtoNOorviceversa
- Replace the bearings
- Service the actuator

6 Technical data
It is important to observe the technical data during installation, operation and maintenance.
Inform the personnel about the technical data.
NC = Normally closed. NO = Normally open. A/A = Air/air activated.
6.1 Technical data
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).
