Abstract

A valve for fluid comprises a body (1) of molded synthetic resin, this body (1) being surrounded by a casing (25) constituted by an extruded profile. This casing (25) has openings (30) in which are fixed plugs (31) having a screw-threaded bore and constituting connectors permitting connecting the valve to the tubing. Joints (34) between the plugs (31) and the valve body are provided to permit relative displacement between these parts without loss of sealing during displacement due to differences of expansion of the members as a function of temperature.
