Abstract
A valve assembly particularly adapted for air conditioning systems and with provision for mounting on a panel or housing wall. The valve assembly has an elongated body with three bosses extending radially therefrom. The body has abutment faces at two of the bosses and has an abutment shoulder at the third boss, which is between the other two bosses. The abutment faces lie in a common plane and are adapted to contact one side of a panel or housing wall that has openings through which the three bosses may project. A jam nut is threaded onto the middle boss for contacting the other side of the panel or housing wall for clamping the same against the abutment faces. The abutment shoulder is inwardly offset a slight distance from the abutment faces to assure that the panel or housing wall will contact the abutment faces when the jam nut is tightened but it will serve as a stop to prevent undue bending of the panel or housing wall under pressure of the jam nut.
