Bailey 707ML Safety Relief Valve Female x Female (Metal Disc with Lever – Suitable for Steam & Liquid Service)

The CONCOA 435 Series regulator provides secondary pressure control for ultra-high purity inert gases, including non-corrosive and liquefied gases. Rated to full cylinder pressure, it’s ideal for point-of-use control in high-purity gas systems. Features include metal-to-metal diaphragm seal, CAPSULE® seats with 360° filtration, pipe-away relief, cleanroom assembly, helium leak-checked integrity, captured vent bonnet, and front/rear panel mounting. Constructed from brass barstock body and bonnet, PTFE seat and internal seals, 316L stainless steel diaphragm, 10-micron sintered bronze filter, 2 in brass gauge, Cv 0.1–0.2, 1/4 in FNPT ports. Temperature range -40°F to 140°F (-40°C to 60°C). Complies with CGA G-4.1, ANSI/ASME B40.1, PED 2014/68/EU, and CRN OH5216.

The Medenus RS255 Gas Pressure Regulator and Shut Off Valve guarantees a consistent outlet pressure, irrespective of the primary inlet pressure. This device adeptly manages variations in gas usage, providing rapid pressure regulation when there are sudden changes in flow rate. Additionally, the integrated safety shut off valve ensures secure operation by shutting off in the event of excessively high or low pressure levels.

The Medenus RS255 Gas Pressure Regulator and Shut Off Valve complies with DVGW Code of Practice G260/262 and is suitable for all neutral and non-corrosive gases (other gases available upon request). It comes with flange connections ranging from DN50 to DN100 and is capable of handling working pressures up to 16 bar. All gas pressure regulators in this range are certified by DVGW and carry CE certification.

Every regulator in the RS series boasts several options, including a safety membrane, vent valve, remote release for the shut off valve (SSV), noise reduction features, and more. For comprehensive details, please consult our documentation or reach out to our team.

The CONCOA 304 Series is a three-port, chrome-plated brass, single-stage point-of-use regulator designed for high-purity, non-corrosive, or liquefied gases (up to grade 5.5). It provides secondary or final-line pressure control, reducing delivery pressure in a single step. Its durable construction and high-purity compatibility make it a cost-effective solution for applications that can tolerate minor outlet pressure fluctuations as cylinder supply decreases. Maximum inlet pressure is 3000 PSIG (210 BAR) or higher, depending on configuration.
