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.
