Target of competition
Donjoy ‘s vision is to be become leading supplier in fluid control, high purity sanitary valve &pump fields, with advanced technology and excellent quality.
Operating Principle
The valve opens when the pressure of the fluid exceeds the pressure to spring, When the two pressures are equalised, the valve closes, A stronger counter – pressure also makes the valve close.

Sanitary valves are two-port valves that feature two separate openings on their body. Fluid enters one opening and exits from the other. These valves help with applications that require liquids to flow in only one direction.
Sanitary valves come in two forms: horizontal and vertical.
Horizontal valves are suited to horizontal lines that need self-draining valves
Vertical valves can be used in either vertical or horizontal installations; in horizontal applications, vertical valves help when self-draining valves can’t maintain pump prime and temperature continuity
In the case of horizontal spring-check valves, product flow pushes a disc in the valve away from the seat. When forward flow pressure is removed, the electropolished spring will return the disc to its original position and hold it against the seat to keep it closed. Backflow pressure will also force the disc into the closed position.
Check valves help in scenarios that require the evacuation of process pipelines. This can occur for a host of reasons, especially those involving product recovery or drainage. Some applications may also require air agitation on the products in the pipelines or in the tanks they lead to. Check valves can accomplish this.
How Does It Work
1. Check valve is a valve that prevents the fluid from flowing back and ensures to flow in only one direction.
2. It can be used to prevent the flow less from returning avoid pipe-hammering.
3. It is used in the food processing,beverages, wine, oil,cosmetics, pharmaceutical and chemical industries.
