MV - High Pressure Gas Control Valve

Designed for manual shut-off and flow control of high-pressure gases in systems operating at elevated pressures.

Suitable for gas cylinder fill plants, manifolds and piping systems as well as applications with inert gases, oxygen, oxidizer gases > 21 %, hydrogen and carbon dioxide, subject to proper system design and media compatibility.

Operating pressure range: vacuum to 380 bar at 70 °F / approx. 21 °C. Versions with NPSM connections are de-rated to 242 bar due to the connection rating.

Allowable operating temperature: -40 °C to +74 °C.

High pressure gas control valve for gas cylinder fill plants, manifolds and piping systems, operating pressure range vacuum to 380 bar at 70 °F / approx. 21 °C.

Function: Manually operated high pressure gas control valve for controlling and shutting off gas flow in systems operating at elevated pressures. The valve geometry allows metering on initial opening and helps minimize initial pressure surges.

Media: Suitable for inert gases, oxygen, oxidizer gases > 21 %, hydrogen and carbon dioxide, subject to proper system design, seal selection and media compatibility.

Testing: 100 % factory tested for internal and external leakage.

Oxygen service: For Material Code C with copper seal: Cleaned and packaged for oxygen service in accordance with CGA G-4.1 as standard. The high pressure oxygen service configuration was third-party tested in accordance with ISO 7291 (O2 Surge) and ASTM G175 (Promoted Ignition). Material Code K with PCTFE seal is not recommended for oxygen service.

Seals / seat options: Material Code C with copper seal for oxygen service; Material Code K with PCTFE seal for positive sealing in non-oxygen applications.

Allowable operating temperature: -40 °C to +74 °C.

Operating pressure: Vacuum to 380 bar at 70 °F / approx. 21 °C. Versions with NPSM connections are de-rated to 242 bar.

Connections: NPT female ports, NPSM male right-hand / left-hand ports or O-ring seal union connection depending on configuration.

Flow: Cv 2.5 for all valve configurations; 2.5 turns from closed to full-open.
