Ordering information

References are formed by three parts:
Valve Code Look for it in the order codes chart on the previous page.
Option/s If required, add the code/s from the options section on the previous page (in alphabetical order).
Material Look for the code on the materials chart.
Example: Single Block and Bleed Valve Flange DN50 PN25 bore 15mm Superduplex with plug in vent port : 1470 T AS
The reference required to place the order is 1470TAS.

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 PN 40, PN64 and PN100.
PEEK Seats for PN160 and PN250.

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.
