MVA - Pneumatically Actuated High Pressure Gas Control Valve

Designed for automated, pneumatically actuated shut-off and flow control of high-pressure gases in systems operating at elevated pressures.

Suitable for automated 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.

Actuation pressure: 5.86 to 8.62 bar. The actuation port must not be pressurized above 8.62 bar.

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

Flow coefficient: Cv 2.5 for all valve configurations.

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

Function: Pneumatically actuated high pressure gas control valve for automated control and shut-off of gas flow. Available as Normally Open (NO) or Normally Closed (NC). 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.

Actuation: Actuation pressure 5.86 to 8.62 bar. The 1/4" NPT actuation port must not be pressurized above 8.62 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.
