Stem
| Vee Steam is standard for pressure tightness even at elevated temperatures. Regulating Stem & Soft-seat Stem are optional. |
|
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.
