CNG Cylinder Valves



We provide various valves for CNG cylinders; both manual valves and automatic valves.

 

Automatic valves:

ASTRO

The Astro valve from OMB is an automatic cylinder valve designed for a purpose: to stop the gas flow from the cylinder in case of an excess flow, e,g, in case of a leak in the piping system. This is achieved by the excess flow valve.

The Astro valve is similar to the Moon valve, but without the micro-venting feature, meaning that it is more suitable for use where the cylinders are not placed in an enclosed space, such as in the underside of trucks.

Specifications:

  • Max working pressure: 260 bar.
  • Working temperature: -40oC ~ 85oC
  • Thermal safety pressure relief device
  • Burst disk
  • Excess flow valve
  • Integrated check valve available on request

 

MOON

The Moon valve from OMB is an automatic cylinder valve designed for a purpose: to stop the gas flow from the cylinder in case of an excess flow, e,g, in case of a leak in the piping system. This is achieved by the excess flow valve.

The Moon valve is similar to the Astro valve, but has the micro-venting feature. This features collects any possible micro-leakages from the functional groups (i.e. the solenoid group, burst disk, etc.) and redirects it, to outside the cylinder enclosure. This means that this valve is more suitable for use where the cylinders will be placed in an enclosed space, such as the car baggage compartment. The micro-venting feature will allow any micro-leakages to flow outside of the baggage compartment, where it may build up to dangerous levels.


Specifications:

  • Ports for micro-venting
  • Max working pressure: 260 bar.
  • Working temperature: -40oC ~ 85oC
  • Thermal safety pressure relief device
  • Burst disk
  • Excess flow valve
  • Integrated check valve available on request
