Series NKL, NKLP, NKS, NKSP, NK, NKP 1.3 Tightening torques All screws greased, tighten in diametrically opposite sequence! 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. For an exception, see Section 8, flange connection valve/pipe is leaking.

Series NKL, NKLP, NKS, NKSP, NK, NKP 2 Page 8 Notes of 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 NKL, NKLP, NKS, NKSP, NK, NKP 3 Page 9 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 NKL, NKLP, NKS, NKSP, NK, NKP 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 NKL, NKLP, NKS, NKSP, NK, NKP 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 Page 11 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 NKL, NKLP, NKS, NKSP, NK, NKP 6.4.1 Additional advice for shut-off and control butterfly valve with actuator For single-acting actuators a locking plate has been fitted into the bracket, blocking the stem at a disc opening of 10 – 15°. Remove the locking plate before the first test actuation, screw in again hex. screw 901/1. Slightly actuate the actuator. Please pay attention to the drawing in Section 5.4. 7 Operation 7.
Series NKL, NKLP, NKS, NKSP, NK, NKP 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.

Displace packing rings 402/1 by 90° against each other Screw in stuffing box screws 901/3. Only tighten in the event of a leak. Safety stuffing box with monitor using warning connection Tighten stuffing box bolts 901/3 with torque in accordance with Section 1.3. See also Section 9.1.3.

The signal penetrates the thickwalled lining. 9.4 Tests Following tests would be done after the assembly. Measurement of the breakaway torque The breakaway torque required for opening and closing the valve is to be ascertained. The maximum torque should not exceed the values given in Section 1.8.

Safety Information / Declaration of No Objection Concerning the Contamination of Richter-Pumps, -Valves and Components 1 SCOPE AND PURPOSE Each entrepreneur (operator) carries the responsibility for the health and safety of his employees. This extends also to the personnel, who implements repairs with the operator or with the contractor. Enclosed declaration is for the information of the contractor concerning the possible contamination of the pumps, valves and component sent in for repair.
Declaration about the Contamination of Richter Pumps, -Valves and Components The repair and/or maintenance of pumps, valves and components can only be implemented if a completely filled out declaration is available. If this is not the case, delay of the work will occur. If this declaration is not attached to the devices, which have to be repaired, the transmission can be rejected. Every aggregate has to have it’s own declaration.
