About this item

The DERNORD Sanitary Check Valve, designed for 1-inch tube OD with a 1.5-inch Tri-Clamp connection, ensures one-way fluid flow in critical industrial processes. Constructed from robust 304 stainless steel with an FKM gasket, this valve is built for reliability in demanding environments. It is 100% tested and inspected, including hydraulic pressure testing, making it a trusted component for preventing backflow in systems handling food, beverages, dairy, brewing, pharmaceuticals, and chemicals. The wetted surfaces are polished for hygiene and ease of cleaning.

This spring-loaded check valve operates automatically based on medium flow pressure. When the pressure below the plug exceeds the pressure above and the spring force, the valve opens. It closes once pressure equalizes, effectively stopping reverse flow. The internal spring is replaceable and the spring plate is rotatable, allowing for pressure adjustment. This design ensures quick disassembly for thorough cleaning, crucial for sanitary applications. The valve is rated for a maximum temperature of 130°C (266°F) and a maximum pressure of 10 Bar (145 PSI).

For Indian industries requiring precise flow control and contamination prevention, this USA-sourced DERNORD check valve offers superior performance compared to standard local alternatives. All customs duties and GST are included in the price, with delivery via ExpressBox tracked shipping. Ensure your process integrity with this high-quality, imported sanitary check valve.

Why choose this product

Engineered for Process Purity

This DERNORD sanitary check valve is engineered for industries where purity and flow control are paramount. Its 304 stainless steel construction and polished wetted surfaces meet stringent hygiene standards. The spring-loaded mechanism, adjustable for precise pressure, ensures reliable one-way flow, preventing costly backflow and contamination in food, beverage, pharmaceutical, and chemical processing lines. Unlike generic valves, it's built for the specific demands of sanitary piping systems, offering peace of mind and operational consistency. Imported directly from authorized US retailers and authorized brand partners, it guarantees authenticity and quality.

Ideal For Hygienic Applications, Skip If...

This valve is ideal for breweries, dairies, pharmaceutical production, and food processing plants requiring strict sanitary conditions and unidirectional fluid movement. It's perfect for systems using Tri-Clamp fittings. Skip this valve if your application involves extremely high pressures beyond 10 Bar (145 PSI) or temperatures exceeding 130°C (266°F), or if you require a different thread standard like NPT or BSP without using adapters. For non-sanitary, heavy-duty industrial applications with less stringent hygiene needs, alternative valve types might be more cost-effective.

How to use

Install Valve in Line — Ensure the process flow direction aligns with the arrow indicator on the valve body. Connect the 1-inch tube OD ends to the 1.5-inch Tri-Clamp fittings on your piping system, ensuring a secure seal.
Verify Flow Direction — Before starting operation, briefly run the medium through the line to confirm the valve opens correctly and allows flow in the intended direction, and closes automatically when flow stops.
Adjust Opening Pressure (Optional) — If needed, disassemble the valve by removing the clamp and carefully accessing the spring. Adjust pressure by rotating the spring plate or replacing the spring (one included) to meet specific process requirements.
Clean Regularly — Disassemble the valve periodically for thorough cleaning, especially in sanitary applications. Ensure all parts are clean before reassembling to maintain hygiene and prevent buildup.
