PVC Check Valves

PVC Check Valves for Water and Industrial Systems

PVC check valves are designed to allow flow in one direction while preventing reverse flow that could damage pumps, pipes or other connected equipment. Made from durable polyvinyl chloride, these valves are widely used in water distribution, irrigation, pool systems and light industrial applications across the USA. Their corrosion resistance, lightweight construction and ease of installation make them a dependable option where reliable backflow prevention is required.

Types of PVC Check Valves

Several types of PVC check valves are available, each designed for specific operating conditions:

• PVC swing check valve: Uses a hinged disc that swings open with forward flow and closes when flow stops or reverses. Commonly installed in horizontal piping systems for low-pressure service.

• PVC ball check valve: Uses a floating ball that seals against the seat when flow reverses. Frequently chosen for sump pumps, wastewater systems and vertical applications.

• PVC spring check valve: Incorporates a spring-loaded mechanism that closes quickly when flow stops, reducing water hammer and maintaining consistent backflow protection.

These variations allow system designers and buyers to select the right configuration based on flow direction orientation and service conditions.

Applications of PVC Check Valves

PVC check valves are used in a wide range of fluid handling systems, including:

• Municipal water systems: Protecting pipelines and pumps from reverse flow.

• Irrigation and agriculture: Regulating water in drip lines, tanks and field systems.

• Pools and spas: Preventing chemical backflow in chlorinated water.

• Industrial processes: Managing flow of compatible fluids in non-corrosive environments.

Their ability to handle both horizontal and vertical flow orientations makes them adaptable to many piping layouts.

Construction and Sizes

PVC check valves are available in threaded, socket and flanged ends, making them compatible with different piping systems. Standard sizes typically range from 1/2 inch to several inches in diameter, covering small residential setups as well as large commercial and municipal systems. The lightweight plastic body resists scaling and corrosion, offering long service life with minimal maintenance.
