GO Regulator LG1 Series single-stage pressure regulators from Circor Instrumentation have been chosen by Clucas MoE for critical duty decreasing and stabilising oxygen released from high pressure cylinders used in rapid entry intervention systems employed by military, anti-terrorist, police forces, fire brigades and similar organisations worldwide. Tailored to incorporate a tamper-proof cap and specifically oxygen cleaned during manufacture, these 316 Stainless body pressure-reducing regulators were selected for this application on the basis of price, quality, reliability and above all its miniature size. LG1 Series regulators can accept high pressures directly from cylinders and other systems, having a 20 micron inlet filter and bubble-tight shutoff. They feature stainless steel diaphragms with Teflon lining, stainless poppets and better than 25 RA finish in diaphragm cavity.
