CPV Manufacturing

What CPV Manufacturing does

CPV Manufacturing (legally Admiral Valve, LLC), founded in 1915 in Kennett Square, Pennsylvania, designs and manufactures high-pressure industrial valves and fittings for safety-critical liquid and gas service. Its proprietary O-Ring Face Seal (ORFS) technology, originally co-developed with the US Navy in the 1950s, delivers self-energizing, bubble-tight seals rated from vacuum to 6,000 PSI, with specialized products rated to 10,000 PSIG. Core product lines include O-SEAL globe and needle valves, Mark VIII direct weld/braze fittings, G-Series compact stainless steel globe valves, FloMaster air-operated valves, and the CryoFlo CFC-50 cryogenic check valve, supplemented by soft goods repair kits and specialized installation tools (stem seal installation tools, valve spacers, flush plugs). Defensible IP sits in the protected O-ring groove geometry, union nut compression design, and self-energizing seal architecture.

The company serves five primary verticals — petrochemical, industrial gas, oil & gas, chlorine, and aerospace/defense — with additional exposure to shipbuilding/marine and emerging CO2 (R744) refrigeration applications. Named reference customers include the US Navy (every aircraft carrier and nuclear submarine), NASA (Gemini and Apollo programs), Praxair's Santo Domingo specialty gas facility, and helium gas-filling operators. Revenue is generated through quote-based direct sales via an inside sales team and website quote request system, alongside a global industrial distributor network; pricing is bespoke with no public price list. Defense-grade certifications (SUBSAFE Level 1, MIL-I-45208, ISO 9001:2015, CSA-B51-09 Annex F) and a documented 30+ year service life on installed valves underpin a stable aftermarket in soft goods and repair kits across the installed base.
