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.

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.
