Subject to technical alterations and misprints! 4 Testing of KLINGER Valves KLINGER Valves are pressure-tested in accordance with EN 12266-1. The pressure test comprises the tests P10, P11 and P12. Testing the resistance to pressure of the ball (P20) is not included in the standard package. - Page 7 wT 2944/02 Page 7...

Page 8: Safety Instructions
6 Safety Instructions This operation manual must be brought to the attention of the operating personnel. 6.1 General Notes on Safety The safety instructions for valves also apply to the pipeline systems, into which they are installed. This operating manual exclusively focuses on safety instructions, which are to be additionally complied with for valves. -
Page 9: Hazard Warnings
» when applying internal pressure for the first time (pressure test, trial operation) a sufficient safety distance is to be maintained. » it is prohibited to open screw connections (with the exception of those on hand levers and handwheels), when pressurized (medium). »... - Page 10 Electromagnetic radiation hazard: » The hazards resulting from possibly created electromagnetic radiation are to be consulted in the operating manual of the actuator manufacturer. Hazards linked to the operational environment: » The ambient atmosphere and the ambient temperature are to be set in a manner that has no negative influence on the valve, the actuator of the valve, and the medium.

A P/T diagram is an ideal tool in order to select a suitable valve for pre-defined operational characteristics. The diagrams illustrate all possible limitations of use of KLINGER valves. CAUTION The area of application for standard valves is from -5 °C up to +200 °C. -
Page 12: Construction Specifics
7.3 Construction Specifics The KLINGER Monoball KHO ball valve series has been specifically designed for utilization in pipe systems operated with high external loads. This includes, amongst others, district heating networks installed by means of the cold laying method. As a result of the high external loads, special measures are required for the design of the body –... -

7.6 Actuating Torques and Widths across Flats of the underground version The operating stem features a hexagon for actuation purposes. It serves as the point of attachment for a suitable socket or flat wrench. From a nominal width of 80 / 100R80 upwards, the shaft pipe is additionally fitted with a hexagon as a counterholder, which enables the utilization of transportable, mountable gear. -

Page 17: Transportation And Storage
Regarding damage obviously resulting from transportation, please contact the freight forwarder in charge of delivery. Monolith KHO ball valves are supplied in the OPEN position with the connections covered in order to protect against dirt and damage. These covers may only be removed immediately prior to installation. -
Page 18: Operating Principle
These rings carry out a double function: They guide the ball and simultaneously absorb the bearing loads. The Monoball KHO ball valve is maintenance-free and can be pressurized in both flow directions. 10 Mode of Operation 10.1 Distribution of force for floating ball... -
Page 19: Operating Stem Seals For The Underground Version
10.2 Operating stem seals for the underground version Sealing of the actuation unit (operating stem) is achieved by means of a primary O-ring seal in double execution, close to the body, and by means of a secondary O-ring seal at the upper end of the operating stem. -
Page 20: Floating Ball Sealing System Design
10.3 Floating Ball Sealing System Design The sealing ring is chambered on three sides by the body and the sealing ring groove. This measure prohibits the sealing material from being swept through the ball as a result of exerted pressure and guarantees a reliably functioning sealing system over a long period of time. -
Page 21: Installation And Putting Into Service Regulations
The ball valve must be in the OPEN position during the entire welding process. This ensures that damaging the ball surface is avoided. KLINGER Monoball KHO ball valves with welding ends can generally be welded into a pipeline by autogenous welding or electric welding (also under protective gas). -
