After the plant has been started up (especially with the first temperature load) the tightening torques must be checked and the correct value set again. The tightening torques for pipe screws and body screws mentioned must not be exceeded.

Series NKS-C, NKSP-C, NKL-C, NKLP-C 2 Page 11 Notes on safety This operating manual contains fundamental information which is to be observed during installation, operation and maintenance. It must therefore be read before installation and commissioning! For valves which are used in potentially explosive areas, see Section 3. Installation and operation are to be performed by qualified staff. The area of responsibility, authority and supervision of the staff must be regulated by the customer.
Series NKS-C, NKSP-C, NKL-C, NKLP-C 3 Page 12 Safety notes for applications in potentially explosive areas based on the Directive 94/9/ EC (Atex 95) The valves are intended for use in a potentially explosive area and are therefore subject to the conformity assessment procedure of the directive 94/9/EC (ATEX).
Series NKS-C, NKSP-C, NKL-C, NKLP-C 4 Safety note for valves, certified to Clean Air Act (TA-Luft) On request, this valve can be supplied compliant with the German Clean Air Code. Certificate / Manufacturer Declaration Validity is dependent on the operating instructions being read and observed. 5 Storage If the valve is not installed immediately after delivery, it must be put into proper storage.
Series NKS-C, NKSP-C, NKL-C, NKLP-C 5.5 Disposal Parts of the valve may be contaminated with medium which is detrimental to health and the environment and therefore cleaning is not sufficient. Risk of personal injury or damage to the environment due to the medium! ♦ Wear protective clothing when work is performed on the valve. 6 ♦ Prior to the disposal of the valve: Collect any medium, etc. which has escaped and dispose of it in accordance with the local regulations.
Series NKS-C, NKSP-C, NKL-C, NKLP-C 7 Operation 7.1 Initial commissioning Normally, the valves have been tested for leaks with air or water. Prior to initial operation check body bolting. For torques see Section 1.4. Unless otherwise agreed, there could be residual amounts of water in the flow section of the valve; this could result in a possible reaction with the medium.
Series NKS-C, NKSP-C, NKL-C, NKLP-C 8 Malfunctions ♦ Flange connection ball valve/pipe is leaking Retighten the flange screws to a tightening torque according to Section 1.3. If this does not remedy the leak, the recommended torques may be exceeded by 10%. If this also fails to stop the leak, dismantle and inspect the ball valve. Dismount and inspect the valve. ♦ Stem passage leaking With no safety stuffing box: Dismount valve and repair.

Marks parallel to the axis of the pipeline: Valve open Marks at right angles to the axis of the pipeline: Valve closed The breakaway torque of the actuator must be at least as high as the breakaway torque of the butterfly valve, about 20% higher being better however.
