Product Description

Orifice: Metering, M/F 1/4 NPT         Metering Orifice Only - A heavy chromed-brass body with an internal pinhole orifice which can govern gas flow rates. Useful for controlling the flow of a reactive gas like oxygen in long delivery lines or in transfiller devices where compressive heating form “fast fills” can be dangerous. When combined with a suitable valve, this device will permit precise metering of a gas into any pressure vessel. For example, with a supply pressure of 1,500 psi upstream, the orifice delivers about 8 cu. ft. of gas per minute which would fill a 80 cu.ft. tank to 3,000 psi in 10 minutes, a charging rate of 300 psi per minute. Now combine this orifice with a compatible valve for further control, and the standard fill rate for mixing (50 - 60 psi / minute) is easy to achieve. This degree of precision control would be difficult to maintain with either the orifice or valve alone. Male / female 1/4” NPT ports. 4,500 psi service. Additional Info: Handling, processing, or mixing Nitrox or pure oxygen requires special equipment which is BOTH oxygen-compatible and oxygen-clean. Most such equipment will be made from brass or stainless steel with softgoods of 02-compatible polymers like Teflon or Kel-F. Many devices suitable for air cannot be used safely in high O2-environments. GMC offers a good selection of hardware for oxygen-related applications. Each item is delivered oxy-clean.
