Abstract

A branch valve for gases or liquids, esp. for feeding pressurised fluid from a main to a branch duct leading to a consuming unit, has a piston seal-type arrangement around the valve slide, comprising a rubber or similar O-ring or analogous sealing ring, and concentric to this and in contact with it, a sealing ring of "Teflon" (RTM) or similar material. In a preferred arrangement, the two rings are mounted in an annular groove on the valve slide, the "Teflon" ring being outside the flexible ring.
