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.

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.

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 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.
