Check Valves

Check Valves

Check valves are essential in systems where fluid must flow in only one direction. We offer a wide selection of miniature check valves including diaphragm, duckbill, spring-loaded, and cartridge styles. Browse by connection type, material, or valve style to find the right fit for your system.

Check Valves Options

  • Plastic Check Valves

    Plastic Check Valves

    We offer a comprehensive line of plastic check valves designed for precise, one-way fluid control in sensitive and demanding applications. Whether you need low cracking pressure or durable performance in industrial systems, our valve options deliver long-lasting reliability. Explore flexible connection styles and specialized features to meet the specific requirements of your application.

  • Plastic Push-In Check Valves

    Plastic Push-In Check Valves

    These push-to-connect check valves offer the one-way flow protection you need without the struggles of connecting to tubing. Simply push-in your tubing and the fitting will securely grab and seal to the outer diameter. Select from various styles, cracking pressures, and connection types.

  • Metal Check Valves

    Metal Check Valves

    Our metal check valves are available in ball, piston, and poppet configurations to suit a wide range of flow control applications. Choose from brass, stainless steel, nickel-plated brass, or aluminum bodies with end connections including NPT thread, hose barb, and compression fittings. Seal options include Buna-N, Viton, EPDM, Neoprene, and Silicone for compatibility with a variety of media. Cracking pressures range from ½ psi to 25 psi, and models are rated for pressures up to 5000 psi. Whether you're managing low-pressure fluid systems or high-pressure gas lines, there's a reliable check valve here to match.

  • Modular Check Valves

    Modular Check Valves

    Modular check valves offer a flexible, component-based solution for low-pressure fluid systems. These valves are composed of interchangeable housings (CVIS Series) and internal cartridges (CRTG Series), allowing for easy customization and maintenance. Choose between spring-loaded or free-floating poppet designs to meet precise flow and shutoff requirements. Port options include hose barbs, push-in fittings, and BSPP threads, with seals available in Buna-N, EPDM, Viton, or silicone. Cracking pressures range from 0.5 to 10 psi, making these valves suitable for a wide range of air, gas, and liquid control applications.
