A push-fit spigot. The spigot includes a push-fit coupling member removably disposed within an internal passage of a body of the spigot. The coupling member enables simple push-fit installation of the spigot on a stub-out in a structure. The coupling member is retained within the internal passage of the spigot by a removable fastener. A removal plate is installed on the stub-out prior to making insertion of the stub-out into the coupling member. Removal of the spigot from an installation on the stub-out is simply performed by removing the fastener between the coupling member and the body to enable removal of the body. The removal plate is then useable to depress a release collar in the coupling member to disengage the push-fit mechanism therein from the stub-out.

A thermostatic cartridge includes: a casing at least partially within and locked translationally along an axis a cartridge body that delimits a chamber, a hot and cold fluid inlet passages and a mixed fluid outlet passage; a slide valve regulating the temperature of the mixed fluid displaceable along the axis to close, in inverse proportions, the inlet passages; a thermostatic element; and a mechanism for adjusting a thermostatic regulation temperature mechanically and displaceably connected to the body and to secure the position of the piston of the element along the axis and to alter the piston position by actuating the adjustment mechanism to move relative to the body. To control the regulation temperature, the casing is rotationally mounted on the body such that the adjustment mechanism is actuated when the casing is between positions-corresponding to extreme low and high temperature values.

A valve device comprises: a housing provided with a flow path; a valve body configured to move in a direction intersecting the flow path, thereby controlling an opening area of the flow path; a bonnet provided with a hollow portion and detachably attached to the housing, the hollow portion extending from the flow path in a radial direction and the valve body being retracted into the hollow portion; and a load receiving portion configured to receive inertia force generated at the bonnet by a rotation torque received by the housing due to external force.

When a part of a hole rear wall of a mounting hole formed in a valve plate and a part of a rod rear wall of a mounting portion of a valve rod have formed thereat inclined portions, respectively, that produce a wedge effect by abutting upon each other and when the valve plate and the valve rod are fixed in a direction of an axis by a valve-plate fixing screw, a wedge effect when the inclined portions and abut upon each other causes a rod front wall of the mounting portion and a hole front wall of the mounting hole to come into close contact with each other and the valve plate and the valve rod to be precisely and firmly fixed to each other so as not to rotate relative to each other.
