CHECK VALVES
Overview
STAINLESS STEEL CHECK VALVES provide passive, automatic backflow prevention for stainless steel piping systems. Designed to allow forward flow and prevent reverse flow, check valves protect pumps, regulators, filtration systems, chemical feed lines, and process equipment from reverse pressure, contamination, or system damage.
Ace Stainless offers a complete stainless check valve lineup including swing check, spring-loaded inline check, dual-plate wafer check, and ball check valves, with options for threaded, socket-weld, wafer, or flanged installation. Valves are available in 304/304L, 316/316L, duplex, and specialty alloys for corrosive and high-performance service environments.
Each valve is engineered for optimal cracking pressure, low pressure drop, and reliable sealing performance in water, chemicals, steam, gas, and high-purity systems.
