In sanitary manufacturing applications that employ the use of fluid systems, such as in the pharmaceutical industry, regulating fluid flow and pressure is essential to maintaining high product and production quality. Common issues—such as backflow, water hammer, and cleanliness – significantly affect the overall effectiveness and efficiency of the system. For these situations, DSV® sanitary check valves serve as an ideal solution.
Why Are DSV® Sanitary Check Valves Important?
Unlike other check valves available on the market, DSV® sanitary valves meet 3A sanitary standard and are designed for use in applications with high sanitation requirements. As such, they are ideal for the manufacturing operations of products intended for consumption or direct contact with consumers, where unsanitary conditions can result in illness or injury. 316L stainless steel offers the corrosion resistance needed to prevent the contamination of process fluids.
By eliminating crevices and cavities from the valve design and achieving smooth, polished finishes on internal and external surfaces, we minimize the risk of material and bacteria buildup in our valves. We test 100% of our check valves before shipping them out to customers.

Additional Information on DSV® Valves
The valve consists of seven main components: body, seat, disc, spring, guide, clamp, and body gasket. Both the disc and seat are lapped to ensure tight shutoff capabilities.

- Horizontal Valves. The horizontal valve models are suitable for use in horizontal piping lines that require a self-draining valve.
- Vertical Valves. The vertical valve models are designed for use in vertical piping lines or horizontal piping lines that do not require a self-draining valve.

A DFT® DSV® Sanitary Check Valve Success
A major engineering firm contacted us on behalf of several pharmaceutical companies. The firm needed to find a check valve solution for their noncorrosive medical waste drain system. The check valve needed to operate at 20 psig or less with a flow of 3 GPM, have sanitary end connections, provide tight shutoff, have a low cracking pressure to open and be able to be steam cleaned in place.
The check valve had to withstand high temperatures, as the firm used 330°F steam to clean the entire medical waste process system 3 times a day. The valve also needed an extremely smooth finish to maintain sanitary conditions.
Responding to the challenge, a DFT® 2 inch DSV® vertical check valve was specified. Designed to prevent flow reversal, this non-slam, full-body valve came equipped with a 0.1-psi cracking pressure spring. We also designed it with tri-clamp connections for ease of disassembly. The product was so successful that… Get the full story in our eBook!
