Choice of Stem
|
Vee Steam is standard for pressure
tightness even at elevated temperatures. Regulating Stem & Soft-seat
Stem are optional. |
 |
Sour Gas Service
|
Materials for wetted valve component
are selected in accordance with NACE standard MR 0175-2000 for sulfide
stress cracking resistant. |
 |
Testing
- Standard Factory Test: Every needle valve is 100% factory tested with
air and nitrogen at 1000psi (69bar) for leakage a the seat and
packing. Each test is performed to maximum allowable leak rate of
0.1sec/min.
- Optional Hydrostatic Test: This hydrostatic shell test is
performed with pure water at 1-1/2 times of the working pressure.
Other optional tests are available upon request.

Safe Valve Selection
|
When selecting the needle valves, the total
system design must be considered to ensure safe, trouble-free
performance. Valve function, materials compatibility, adequate ratings,
proper installation, operation and maintenance are the responsibility of
the system designer or user.
