Maintenance Adjustment of the needle packing may be necessary during the working life of the valve. The operation consists of turning the nut (16) clockwise. Ball Valves with long no-working period may have a harder initial operating torque. Tests
100% tested in accordance to API STANDARD 598. Each valve is tested to check the leakage in the seats and packing. Upon request, the corresponding materials and test certificates can be delivered with the valve. Seats* Reinforced PTFE Seats for Class 150, Class 300 and Class 600.
PEEK Seats for Class 900 and Class 1500. Elastomers & Seats O-ring seals (positions 6 and 11) can be made of different materials: Nitrile B , EPDM E or Neopren N , considering the working conditions and fluid of the valve. |
