Sanitary manufacturing applications that use fluid systems, such as the pharmaceutical industry, use check valves to regulate fluid flow and pressure. This is crucial for maintaining high product and production quality. DSV® sanitary check valves ensure overall effectiveness and system efficiency by serving as an ideal solution for common issues such as backflow, water hammer, and cleanliness.

Pharmaceutical Check Valve Considerations

There are many features and design considerations that must be taken into account when choosing a pharmaceutical check valve. To ensure you’re choosing the right valve type for your intended application, consider the following features:

Pharmaceutical glass bottles production line

  • Meeting Sanitary 3A Standard 58-02.
  • Clean-in-Place Design. This design allows for easy cleaning without disassembly of the system. Some design elements include crevice-free construction to reduce material entrapment, high temperature O-rings, a polished surface to reduce the risk of buildup, and stainless-steel construction to prevent corrosion.
  • Non-Slam Spring Assisted Silent Closing. This closing mechanism prevents the possibility of flow reversal and eliminates water hammer. The spring ensures that only fluid with the proper minimum pressure can pass through the valve.
  • Tight Shut-Off. Lapping the seat and disc ensures tight shut off, which lowers the risk of backflow.

DFT® Check Valve Products for Pharmaceutical Applications

At DFT®, we provide two main types of pharmaceutical check valves: horizontal valves and vertical valves.

Horizontal Valves

These valves are designed for horizontal piping lines that require a self-draining valve. The forward moving pressurized fluid pushes against the disc and separates it from the valve seat to allow fluid to pass through the gap. One forward flowing pressure is removed, and back flowing pressure is introduced, the disc returns to a closed position stopping fluid flow.

Vertical Valves

Vertical valves are suitable for two main types of locations: vertical pipes and horizontal pipes that don’t need self-draining capabilities. Each vertical valve has a gasket body seal and a quick-release clamp that operators and maintenance staff can use to easily access the valve components for repairs and other maintenance.

Along with our selection of standard horizontal and vertical pharmaceutical check valves, DFT® provides the following valves suitable for steam and utility systems:
