Concoca 312 Series Dual Stage Cylinder Regulator | Five-port, Chrome-plated Brass Barstock
Item#: 312RegulatorThe 312 Series regulator provides primary pressure control for non-corrosive, high purity (up to grade 5.5), or liquefied gases. Two stages of pressure regulation minimize pressure variation arising from inlet pressure changes, such as the depletion of the supply cylinder, making the 312 Series regulator ideal for applications where constant delivery pressure is critical. Available with a variety of options installed at the factory, the 312 Series regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
- 316L stainless steel diaphragm prevents inboard diffusion
- CAPSULE® seat design features integral 360° filtration in both stages
- Spectrometric helium leak check verifies leak integrity
