Check Valves
Check valves are mechanical devices designed to allow fluid—whether liquid or gas—to flow in only one direction, preventing backflow that can damage equipment or disrupt system performance. Commonly used in industrial, plumbing, and MRO (maintenance, repair, and operations) systems, they automatically open with forward flow and close when flow reverses. Available in various types like swing, ball, and inline designs, check valves are essential for ensuring system integrity, protecting pumps and compressors, and maintaining operational safety.
Types of Check Valves We Offer:
- Swing Check Valves – Ideal for irrigation and low-pressure systems
- Ball Check Valves – Reliable for wastewater and slurry applications
- Piston Check Valves – Designed for precise flow control in hydraulic systems

FAQS
- A check valve is a one way valve that allows fluid to flow in one direction only and automatically prevents backflow in a piping system.
- A check valve opens when fluid flows in the correct direction and closes when flow stops or reverses. The closing mechanism may use a disc, ball, flap, or spring depending on the valve design.
- Check valves are used to protect pumps, compressors, piping, and equipment from damage caused by reverse flow. They are commonly installed on pump discharge lines.
- Swing check valves rely on gravity and flow to open and close, while spring loaded check valves use a spring to close quickly and reduce water hammer.
- Check valves are made from materials such as cast iron, ductile iron, stainless steel, brass, bronze, PVC, CPVC, and other plastics depending on application needs.
