摘要： A seal means for a cylindrical type slide valve in which the valve element (14) is arranged to control one or more fluid flow ports in a valve housing (10) comprises a number of O-rings (24-29) mounted in circumferential grooves on the valve element (14) and a thin-walled plastic sleeve (31/) mounted by shrinking on said valve element (14). The sleeve (31) assumes substantially the same outer contour as the valve element (14) and the O-rings (24-29) had before the sleeve (31) was mounted. The sleeve consists of a autocrosslinkable high density polyethylene with self-lubricating properties.
