Spring Check Valves

Spring check valves offer high performance, fast acting backflow prevention in a compact, maintenance free design. These valves use a spring assisted mechanism to ensure a rapid, positive shutoff the moment forward flow ceases in pipelines. The spring loaded action prevents slamming and water hammer, effectively protecting sensitive equipment and ensuring quiet operation. Their reliable, fast acting response makes them an excellent choice for high profile systems where backflow must be stopped instantly.

Each spring check valve features a clearly marked flow arrow for straightforward installation. Valve bodies are manufactured from corrosion resistant PVC for broad chemical compatibility and feature stainless steel springs and durable EPDM or FPM seat options to match different temperature and media requirements. Their low profile design makes them ideal for applications where space is tight and operational reliability is non-negotiable.

Features & Options

• Slam Prevention: The spring assisted closure provides a quick, non-slam response to protect your piping system.
• Positive Shutoff: The weighted disc and spring action work together to create a reliable, leak free seal against backpressure.
• Versatile Installation: Can be installed in horizontal or vertical flow (up-flow only) configurations for flexible system design.
• Robust Construction: Made from chemical resistant PVC, thermoplastic and stainless steel components for long life and service.
• Leak Free Seal: High quality seat materials for reliable, leak tight performance under varying conditions.
• Space Saving: Compact body simplifies integration into new or existing systems where space may be limited.
• Easy Connection: Come with true union connections for easy installation, maintenance, and replacement.

Common Industry Uses

Spring check valves are used in pipelines where instant, automatic backflow prevention is required. Common industries and uses include water and wastewater treatment, irrigation, aquaculture, swimming pools and spas, and commercial building systems such as HVAC, plumbing, and fire protection. They are also trusted in industrial processing, OEM assemblies, and data centers to protect piping, equipment, and sensitive infrastructure from reverse flow events.
