New dome seal valves for use in food processing can significantly cut costs compared with existing models, according to manufacturers James Walker Keaflex.

Available in a wide range of sizes, the dome seals are made mainly from Elast-O-Pure, an ethylene-propylene synthetic rubber.

They are also available in other materials including silicone rubber, fluorocarbon rubber NBR and HNBR chloroprene, the company says.

Bulk materials

The simple design and high reliability of dome valves have led to their adoption in a wide range of industries, including the food sector, for controlling the flow of bulk materials such as powders, pastes and granules,” ​according to the manufacturers. “The valves are compressed air operated and use an inflatable sealing mechanism which provides a pressure tight seal against the dome when the position in closed​.”

Standard dome diameters range from 50mm to 400mm with other sizes available from the company on request.

Prices of the dome seals, which are available worldwide, depend on specification and the size of the order, says James Walker Keaflex.

Food processing

The company also supplies polytetrafluoroethene (PTFE) gasket products that comply to food processing requirements.

Also for the food sector, the company can providecomponents in food quality polyurethane and numerous thermosets. Products include balls and diaphragms for valves, pumps, bottle filling machine parts, can seals to meat de-boners and poultry meat diaphragms, in super tough polyurethane.
