The Series MV High Pressure Gas Control Valve is optimized for the demanding requirements of Gas Cylinder Fill Plants, Manifold, and Piping System applications. The Copper (C) configuration was third-party tested per ISO 7291 (O₂ Surge) and ASTM G175 (Promoted Ignition) for Oxygen service.
Features a needle thrust bearing for low operating torque throughout the full pressure range, unique valve geometry for flow metering on initial opening, and 2.5 turns from closed to full-open. Fully field re-buildable. Available in standard and panel mount configurations. Vacuum to 5500 PSIG.
- Oxygen Safe: Copper (C) Configuration Third-Party Tested per ISO 7291 (O₂ Surge) and ASTM G175 (Promoted Ignition)
- Low Torque: Needle Thrust Bearing Maintains <10 in-lbs Operating Torque Throughout Full Pressure Range
- Flow Control: Unique Valve Geometry Allows Metering on Initial Opening — Minimizes Initial Pressure Surges
- Fast Opening: 2.5 Turns from Closed to Full-Open
- High Flow: Large Orifices and Internal Flow Paths for Maximum Flow Efficiency — Cv 2.5 for All Configurations
- Long Service Life: Non-Rotating Poppet and Non-Rising Stem Maintain Seat and Seal Integrity
- Field Re-Buildable: All Valves are Fully Field Re-Buildable
- Panel Mount: MVP Version Supplied with Two Panel Nuts for Easy Retro-Fitting to Existing Installations
- 100% Factory Tested for Internal and External Leakage
- Operating Pressure Range: Vacuum (29 inHg) to 5500 PSIG (380 bar) @ 70°F — MAWP per ASME BPVC Section VIII Division 1
- Note: NPSM Connections (1" 11.5 NPSM) de-rated to 3500 PSIG (242 bar) due to connection's maximum pressure rating
- Operating Temperature Range: -40°F to 165°F (-40°C to 74°C)
- Flow Coefficient (Cv): 2.5 for all valve configurations
- Orifice: 0.406" (10.3 mm)
- Leakage: No bubbles visible for 10 seconds with N₂ gas at 2500 PSI
- Copper (C) configuration: Copper poppet insert, Monel® 400 seat and stem
- PCTFE (K) configuration: PCTFE poppet insert, 303 SS seat and stem
- Note: Generant does not recommend PCTFE (K) in Oxygen Service
- Panel Mount (MVP): 1-5/8" diameter hole required; back of panel to port centerline: 2-3/8" to 3"
