Description

Westlake Pipe & Fittings V40601N 4″ Wafer Check Valve with Stainless Steel Spring

The Westlake Pipe & Fittings V40601N 4″ Wafer Check Valve with Stainless Steel Spring is a high-performance flow control device designed to prevent reverse flow in pressurized piping systems. Its wafer-style design allows for compact installation between standard flanges, making it ideal for tight spaces, retrofits, or mechanical rooms while maintaining reliable backflow protection in commercial, industrial, and municipal fluid-handling systems.

The valve features a stainless steel spring that ensures rapid, controlled closure of the disc when flow stops or reverses. This spring-assisted mechanism provides dependable backflow prevention even in low-flow or vertical applications where gravity-based check valves may fail. The stainless steel spring resists corrosion, delivering long-term durability and protecting downstream equipment from water hammer, pressure surges, and potential damage.

Its internal design promotes smooth flow in the intended direction while minimizing pressure loss. The disc opens easily with forward flow and closes securely when flow reverses, providing efficient operation and reliable system protection. The wafer-style body ensures easy alignment and installation with standard flange connections, without the need for additional pipe length or modifications.

The V40601N 4″ wafer check valve is suitable for pool and spa circulation, irrigation networks, HVAC systems, water treatment facilities, and industrial process piping. Its robust construction supports both indoor and outdoor installations, while maintaining consistent, long-lasting performance under repeated use. Westlake Pipe & Fittings is recognized for professional-grade, dependable piping components, and the V40601N reflects this commitment. Its combination of compact design, stainless steel spring mechanism, and durable construction makes it an essential component for maintaining proper flow, protecting equipment, and ensuring system efficiency in applications where backflow prevention is critical.
