Abstract: A thermostatic valve includes a hollow body, two openings opening into the body and being hydraulically connected by a pass section, and a shut-off component arranged partially in the pass section and having a thermostatic actuator, a return component, a valve capable of opening the first opening when actuated by the thermostatic actuator and of closing the first opening when returned by the return component. The thermostatic actuator includes a cylinder containing an expansion material and a stem defining an axial direction. A relative movement between the cylinder and the stem along the axial direction occurs under the action of the expansion material. The stem bears at an ends against an abutment element, which is movable under the action of movement component in the direction of the cylinder to allow the opening of the first opening when the temperature of the expansion material is below the threshold temperature.

Abstract: Cryogenic valves are disclosed. A valve for includes a valve body, a valve seat, a gland nut coupled to the valve body, and a lower spindle threadably engaged to the valve body. The lower spindle defines a first bore. The valve includes a seat disc mounted to the lower spindle and configured to engage the valve seat in a closed configuration and be disengaged from the valve seat in an open configuration. The valve includes an upper spindle defining a spring bore. A portion of the upper spindle is received in the first bore to matingly engage the upper spindle to the lower spindle such that rotation of the upper spindle causes rotation of the lower spindle. The valve includes a spring that is at least partially disposed in the spring bore of the upper spindle and is configured to bias the upper spindle to sealingly engage the gland nut.

Abstract: An electrically driven actuator for opening and closing a valve comprises: an electric motor (1); a movable plate (8), to which a valve body is connected; a conversion mechanism (3) configured to convert a rotational motion of the electric motor (1) to a linear motion; a first biasing member (11) configured to bias the movable plate (8) toward a first direction; and a second biasing member (12) configured to bias the conversion mechanism (3) toward a second direction. The valve body is to be opened when a part of the conversion mechanism (3) linearly moves to move the movable plate (8) toward the second direction, and is to be closed when the first biasing member (11) biases the movable plate (8) toward the first direction. The conversion mechanism (3) is configured to be displaced relative to the movable plate (8) in a state in which the valve body is closed.

Abstract: A rotary handle is attached to a hot water single faucet and is a handle for controlling water discharge by rotational operation by an operator. A coefficient of friction of a grip member is set large in order to guide fingers of the operator to the grip member (operation surface) installed at a part of an outer surface of the rotary handle when the operator grasps the rotary handle. The grip member forms a line-shaped operation surface extending to a position not reaching a joint position of the rotary handle and the hot water single faucet along the outer surface in a direction of an axis of rotation.
