Page 5: Proper Use
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 piston (P20) is not included in the standard package. -
Page 6: 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 7: 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 8 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.

Page 11: Tightening Torques
7.3 Tightening Torques The values provided below are approximations and valid for lubricated stud bolts and nuts. Valves, which have already been in operation over longer periods of time, and already show wear and tear on the sealing surfaces and/or are not tight at higher pressures due to gaseous media, can be made tight again by retightening the bonnet securing nut (Pos. -
Page 12: Transportation And Storage
Furthermore, it should be ensured that the valves and possibly mounted actuators have not been damaged during transport. Please also check that the supplied valves (types, nominal sizes etc.) correspond with the order. KLINGER Fluid Control is to be notified immediately of any kind of deviations. Regarding damage obviously resulting from transportation, please contact the freight forwarder in charge of delivery. -
Page 13: Installation And Putting Into Service Regulations
10 Installation and Putting into Service Regulations Piston valves can be installed into the pipe system in any given orientation. The preferred flow direction, however, should be taken into consideration in this context. This series of piston valves is equipped with a pressure compensated piston and therefore does not show any piston pump effect. -
Page 14: Service And Maintenance
11 Service and Maintenance Maintenance and inspection intervals are to be determined by the operator dependent on the operating mode, as these valves can be utilized under a number of different operating conditions. Maintenance and inspection work may only be carried out by trained personnel. -

Page 18: Conversion Of An On/Off Valve To A Control Valve
12 Conversion of an on/off Valve to a Control Valve The difference between a KVN piston valve and a KVRLN control valve is the lantern bush. The control lantern bush features a defined geometry, which results in an almost linear flow curve and simplifies the control of media flows. -
