It delivers outlet pressures in the range of 50 to 750 psig and is rated for use with air, oxygen, inert gases, and hydrogen. The body is machined brass with a brass housing cap, and the unit uses a stainless steel diaphragm for reliable, consistent performance. A cartridge-type seat assembly with a PCTFE seat provides durable shutoff across a wide range of flow conditions. Licensed HVAC and industrial gas technicians are the typical installers for this class of equipment.\u003c\/p\u003e\n\u003cp\u003eThe 0781-1457 is suited for manifold installations in industrial, laboratory, and commercial settings where high flow and stable two-stage pressure regulation are required. It handles high-pressure cylinder banks supplying air, oxygen, inert gas, or hydrogen to downstream equipment. The inlet connection is 1 inch - 11.5 M NPS with a bronze sintered inlet filter, and the outlet connection is 1 inch - 11.5 F NPS fitted with a Delrin cap bushing for smooth pressure adjustment. This regulator is appropriate for both single-cylinder and multi-cylinder manifold setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMachined brass body and housing cap for durability in demanding service environments\u003c\/li\u003e\n  \u003cli\u003eTwo-stage piston-type actuation provides stable outlet pressure across varying inlet conditions\u003c\/li\u003e\n  \u003cli\u003eCartridge-type seat assembly with PCTFE seat accommodates a wide range of flow capacities\u003c\/li\u003e\n  \u003cli\u003eStainless steel diaphragm for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eBronze sintered inlet filter protects seat and downstream components from particulate contamination\u003c\/li\u003e\n  \u003cli\u003eDelrin cap bushing on outlet connection enables smooth, precise pressure adjustment\u003c\/li\u003e\n  \u003cli\u003eExternal adjustable relief valve on F and G range models; hydrogen models include ventable relief valves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe VICTOR 0781-1457 is part of the SR 4MF Series and is compatible with high-pressure air, oxygen, inert gas, and hydrogen supply systems.

Always shut off the cylinder supply valve and relieve system pressure completely before connecting or removing a regulator. Inspect the inlet filter and all fittings prior to pressurization, and verify that the regulator is rated for the specific gas being used. Follow all local codes and the Compressed Gas Association guidelines for safe handling of high-pressure cylinders and manifold equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulator Type\u003c\/strong\u003e: Two Stage, High Capacity Manifold Piston\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDelivery Pressure Range\u003c\/strong\u003e: 50 to 750 psig\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Gases\u003c\/strong\u003e: Air, Oxygen, Inert Gas, Hydrogen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Machined Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiaphragm Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: PCTFE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Filter Material\u003c\/strong\u003e: Bronze Sintered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1 inch - 11.5 M NPS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 1 inch - 11.5 F NPS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge Size\u003c\/strong\u003e: 2.5 inches Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VICTOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0781-1457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VICTOR","offers":[{"title":"Default Title","offer_id":51346436555058,"sku":"0781-1457","price":2170.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546327.jpg?v=1782080214","url":"https:\/\/voomisupply.com\/products\/victor-0781-1457-two-stage-high-capacity-manifold-regulator","provider":"Voomi Supply","version":"1.0","type":"link"}
