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 this connection’s maximum pressure rating.
  • Operating Temperature Rating: -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

Materials of Construction

  • Brass Body Construction
