High Pressure Gas Control Valve


NPT Female x Female, NPSM Male RH & LH, O’Ring Seal Union
Vacuum (29 inHg) – 5500 Psig (380 Bar)


Description

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 High Pressure Oxygen Service Valve Configuration (Material Code “C”) was third party tested per ISO 7291 (O2 Surge) and ASTM G175 (Promoted Ignition). The valve is also available with a PCTFE seal (Material Code “K”) for positive sealing in non-oxygen applications. The Series MV is available in a variety of porting and mounting configurations. The panel mount configuration is supplied with two panel nuts for easy retro-fitting to existing panel mount installations.

Features

  • Oxygen Safe: Copper Valve (Material Code “C”) Configuration Third Party Tested per ISO 7291 (O2 Surge) and ASTM G175 (Promoted Ignition)
  • Low Torque: Needle Thrust Bearing Maintains Low Operating Torque (< 10 in-lbs) Throughout Full Pressure Range
  • Flow Control: Unique Valve Geometry Allows User to Meter Flow on Initial Opening and Minimizes Initial Pressure Surges
  • Long Service Life: Optimized Material and Component Selection for Long Service Life; Non-Rotating Poppet and Non-Rising Stem Maintain Seat and Seal Integrity, Needle Thrust Bearing Efficiently Minimizes Wear Effects of Mechanical Load
  • Fast Opening: 2.5 turns from Closed to Full-Open
  • High Flow: Large Orifices and Internal Flow Paths for Maximum Flow Efficiency
  • Field Re-Buildable: All Valves are Fully Field Re-Buildable
  • Adaptable to Existing Installations: Panel mount version supplied with two panel nuts for easy retro-fitting to existing installations

Technical Data

  • Operating Pressure Range: Vacuum to 5500 Psig (380 Bar)@ 70°F (MAWP Rating per ASME BPVC Section VIII Division 1)
    • Note: Valves with NPSM Connections (1” - 11.5 NPSM) are de-rated to 3500 Psig (242 bar) due to the connection’s maximum pressure rating.
  • Operating Temperature Range: -40° to 165°F (-40° to 74°C)
  • Flow Coefficient: Cv is 2.5 for all valve configurations
  • Valves are 100% Factory Tested for Internal and External Leakage
    • No bubbles visible for 10 seconds with N2 gas at 2500 PSI.

How To Order


PROPER COMPONENT SELECTION - When specifying a component, the total system design must be considered to ensure safe and trouble-free performance. Intended component function, materials compatibility, pressure ratings, installation, environment and maintenance are the responsibility of the system designer.

Repair Kits

Kits can be ordered as assembled cartridges that simply plug into the valve body or as loose replacement parts. Repair Kit MV2-C may require a replacement stem. Our “Series MV Repair Kit Selection Guide” provides detailed information on how to specify and order repair kits.
