Page 5: Installation
Installation Valve actuator The valve is normally equipped with an actuator. Depending on the application it can be a hand lever or a remotely controlled pneumatic or electric actuator. The actuator may have limit switches (on-off application) or positioner (continuous control). Installation This product shall only be inspected, installed and used by a person who has relevant training or experience. - Page 6 IMPORTANT! Install the valve in such position that injury on person, or damage on property, is avoided in case of leakage from sealing or flange joints. Also, make sure that, in case of leakage, inflammable media do not come in contact with electrical components or hot surfaces which can cause fire or damage on property.

Page 7: Maintenance
Startup The valve shall be operated and controlled that closing- and opening functions are correct before start- up. Check that the valve operates within its max- and min-positions. Limit-switches, positioner, feed- back signal and torque switches shall be checked for correct function. Start-up shall be done gradually and under careful attention. - Page 8 Disassembly DN 25 (1") a) Loosen and remove screws (11) and inlet cover ring (2). b) Lift out seat ring (10) carefully from its groove using a pointed tool. and the O-rings (15 and 16). Loosen the nut (12) and pull out fastening flange (1A). d) Push bearing sleeve (4) into the valve and remove split ring (4A).
- Page 9 Reassembly Proceed in reverse order. O-rings (13, 14 15 and 16) shall be lubricated with suitable grease before reassembling. Please note ”Important when assembling ” below. If the o-rings show sign of wear or other damage, check if the most appropriate o-ring material has been used. Check the sliding ring (13A) replace if necessary.
- Page 10 After reassembly Pressure test the valve with air from the valves outlet side and with the valve closed. The valve immersed in water or with leakage spray shall be bubble tight over shaft seals and seat. I small bubbles can be detected around the shafts it can be enough to actuate the valve a few times allowing the O-rings to find its correct position.
