Packaging Details

Bubble pack for each valve.

Outside packing are carton or plywood cases.

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

 

 

What Are Sanitary Valves Used For?

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.

 

Things to Keep in Mind When Installing a Sanitary Check Valve

 

– Ball Check Valve –

In a vertical setting, the product has to flow from bottom to top so that gravity can push the ball in and out of the seat.In a horizontal setting, the curved portion of the valve needs to be upright and at 90 degrees to the pipe. This makes sure that the valve is free-draining and the ball sits properly.

– Disk Check Valve –

Disk Check Valves are not free-draining in a vertical setting. Therefore, for them to be free-draining, they need to be in a horizontal position.
