Product Summary

A double seal ball valve is used to control the directional flow of high pressure material through a pipeline comprising a primary seal and a secondary seal, each operating independently, in proper sequence, each acting in the same direction, and each being pressure actuated, with provision for relieving excess fluid pressure. The body of double seal ball valves may be made of plastic, metal or metal with a ceramic center and the ball itself is often chrome plated to make it have a good corrosion resisting. A double seal ball valve is an excellent choice for shutoff applications because they are durable and usually work to achieve perfect shutoff even after years of disuse.
