  • Page 3: Functional Principle

    2575/11 Page 3 FUNCTIONAL PRINCIPLE Because of the ELASTIC SEALING SYSTEM, the KLINGER Ballostar KHE ball valve is absolutely ® leak tight at high, but also at extremely low pressures. The required contact forces between sealing ring and ball are created by the differential pressure in the ball valve. For the FLOATING BALL sealing principle it is important that the shut-off device is freely moveable.

  • Page 4: Mode Of Operation

    The fluid pressure presses the ball against the downstream located sealing ring. At the same time, the upstream located sealing element is pressed against the ball. Because of the elasticity of the KLINGER sealing system two sealing areas are permanently available in the bore.
  • Page 5 Low differential pressures: FV-F1 > F1 …upstream located sealing ring is in full function ® KLINGER Ballostar KHE ball valves are basically maintenance free and can be pressurized in both flow directions. The U-sleeve which is drawn onto the supporting ring is completely chambered and seals the pitch flange against the outside.
  • Page 6 wT 2575/11 Page 6 THE EXTERNAL SEALING SYSTEM The sealing of the shifting shaft (operating stem) is carried out by a belleville washer supported stuffing box. This type of sealing is almost maintenance free and has just little set-off behaviour. Only small tightening forces are required for leak tightness.
  • Page 7 We recommend removing the caps not until you want to install the valve. KLINGER valves should be stored in closed rooms with non- aggressive ambient atmosphere and where they are protected from moisture and dirt. Furthermore the maximum temperatures and pressures, specified in the P/T-diagrams, should not be exceeded during operation.

  • Page 8: Material Code

    During long periods of non-operating, the valves have to be drained. In case of leakage the screws of the body have to be retightened. Please check table No.1 for the required torque values! KLINGER recommends operating the valve minimum six times a year to increase the service life! Table 1: Tightening torques and wrench sizes (SW) Size ½”...

  • Page 16: Installation Of Valve, Mounting Of Actuator

    Page 16 INSTALLATION OF VALVE Although KHE ball valves can be pressurised in both flow directions, KLINGER recommends a preferred mounting direction. The correct mounting direction is marked with an arrow on the valve body. This ensures that the flange end piece (respective the elastic sealing element) of the ball valve is positioned upstream.
