5. Features & Design
-
Packing Below Threads: Packing is located below the stem threads to prevent system media from coming into contact with the threads, reducing corrosion and fugitive emissions.
-
Non-Rotating Stem Tip: Prevents galling (scoring) of the seat and stem tip, ensuring leak-tight shut-off and extending cycle life.
-
Live-Loaded Packing: (Optional/Standard on some series) Utilizes a spring (Belleville washer) to maintain constant pressure on the packing, compensating for wear and temperature changes.
-
Panel Mountable: Standard feature on most forged body designs.
-
Safety Backstop: A handle stop prevents over-tightening and potential stem blowout.
6. Applicable Standards & Testing
-
Design Standard: Designed to meet ANSI B16.34 / ASME standards.
-
Inspection: Each valve is factory-tested for bubble-tight leakage at both the seat and the packing.
-
Cleaning: Standard cleaning per ASTM G93 (or equivalent) for instrumentation and oxygen service (Special cleaning SC-11 available).
-
Compliance: NACE MR0175 / ISO 15156 compliance available upon request for sour gas service.
7. How to Order (Typical Configuration Code)
When ordering, specify the configuration as follows:
| Element | Example Options |
|---|---|
| 1. Series | (e.g., 2219, 1700, “V” Series) |
| 2. Body Material | M = Monel |
| 3. End Connections | G = Gyrolok® / Tube Fitting F = Female NPT |
| 4. Connection Size | 4 = 1/4″ 6 = 3/8″ 8 = 1/2″ 12MM = 12mm |
| 5. Stem Type | VS = Vee Regulating VF = Soft Seat |
Ordering Example: 2219-G8M (2219 Series, Gyrolok 1/2″, Monel Body)
