316 Stainless Steel Spring Check Valve – Compact, High-Pressure Backflow Prevention for Water, Oil, Steam, Gas | 2 PSI Cracking, All-Metal Design

Spring-Loaded Type 316 Stainless Steel Check Valve | Compact, High-Pressure, All-Stainless Design

Engineered for demanding environments, the Spring-Loaded Type 316 Stainless Steel Check Valve delivers dependable backflow prevention in a compact, corrosion-resistant design. Constructed entirely from Type 316 stainless steel, this valve is ideal for water, oil, and gas systems up to 1000 psi and steam applications up to 150 psi. Designed for longevity and precision, it performs reliably in both horizontal and vertical installations, making it suitable for tight or high-performance piping systems.

Key Features: Durable, Precise, and Versatile

• All-316 Stainless Steel Construction: Corrosion-resistant and durable for harsh industrial, marine, or chemical environments.

• Spring-Loaded Design: Ensures fast, positive shutoff against reverse flow — minimizing water hammer and vibration.

• Wide Compatibility: Rated for water, oil, and gas up to 1000 psi, and steam up to 150 psi.

• Temperature Range: Operates reliably from -28°C (-20°F) to 150°C (302°F).

• 2 psi Cracking Pressure: Allows consistent opening and closing even under low differential pressures.

• Compact & Low-Maintenance: Streamlined profile ideal for confined spaces or retrofits.

• Thread type: Has female pipe threads (FPT) on both ends of the valve.

Swing vs. Spring — Why Choose Spring-Loaded?

While swing check valves use a hinged disc that opens with flow and closes by gravity or back pressure, spring check valves use a spring-loaded poppet for faster, more reliable closure.

• Spring check valves offer quiet operation, compact design, and installation flexibility in any orientation.

• Swing check valves allow higher flow but are bulkier, orientation-sensitive, and noisier.

Built for Professional Use

Whether installed in a hydraulic system, steam line, chemical process, or marine service, this spring-loaded stainless steel check valve delivers efficient, corrosion-resistant, and maintenance-free performance for years of dependable service.
