Abstract

A gate valve (10) has a hollow substantially T-shaped housing (12) having opposed tubular ends (14) through which a pair of removable coaxial sleeves (28, 30) extend, the sleeves terminating in the interior of the housing in a pair of spaced-apart seats (34, 36). A gate (38) includes a lion pair of gate members (40, 42) moved by a structure (52, 54, 56, 58, 64, 66) which when operated in one sense, first displaces the gates transversely to the common axis of the sleeves until the gates are in a position of alignment with the sleeves, and then while the structure which moves the gates continues to operate in the same one sense, a stop (82) engages the gate members and cooperates therewith to guide them for movement parallel to the common axis of the sleeves into engagement with the seats. The sleeves serve to protect the housing from the effects of temperature fluctuations of the fluid flowing through the sleeves. Preferably the sleeves and the other components of the valve are made of forged or rolled steel. <IMAGE>
