A fixing structure for solenoid (10) includes a valve body (50) including a tubular valve insertion portion (51), a solenoid (10) to be inserted into the valve insertion portion (51), a cover (60) to cover the valve body (50) in a direction intersecting an inserting direction of the solenoid (10) into the valve insertion portion (51), and a pin (40) to be inserted and pierced through the valve insertion portion (51) and the solenoid (10) from the side of the cover (60), thereby restricting detachment of the solenoid (10) from the valve insertion portion (51). The cover (60) includes a resilient pressing piece (61) to be pressed against the pin (40) and resiliently deformed when inserting the pin (40) and to hold an inserted state of the pin (40) by resiliently returning and pressing an end of the pin (40) when the insertion of the pin (40) is completed.

A single waterway shaft structure includes a valve housing, a valve cover, a temperature control rod assembly composed of a water stopper and a temperature adjustment rod, a spring, and a gasket. A lower portion of the temperature control rod assembly is formed with an eccentric water hole. The gasket and the spring are placed in an eccentric water inlet of the valve housing in order and confined in the valve housing. The temperature control rod assembly cooperates with a faucet handle. A one-way connecting structure is provided between the valve cover and the valve housing. An upper end of the valve cover is provided with a fan-shaped limit block for limiting the turning angle of the temperature control rod assembly. The shaft is designed to be one-piece.

A valve, in particular for hydraulic circuits, includes a valve body (4) designed as a cartridge that can be fixed in a housing (6) having fluid connections (8) by a securing device (20, 26, 28). The securing device has at least one blocking element (20) in the form of a separate component between the valve body (4) and the housing (6). The blocking element has blocking surfaces that can be moved relative to the longitudinal axis (18) of the valve body (4) between an assembly position allowing the valve body (4) to be inserted into the housing (6) and a blocking position in which the blocking surfaces secure the valve body in an assembly position, preferably with zero backlash by bearing against retaining surfaces (26, 28) of the housing (6) and the valve body (4).

A curb stop device for aligning a curb stop box and a valve is disclosed herein. The curb stop device may include a side wall and a bottom wall, with the bottom wall including one or more flexible tabs and an inner aperture. The inner aperture may be configured to receive the valve, such as a water shut-off valve.

An alarm valve station (80) of a fire extinguishing system (100) includes a fire extinguishing system valve (1) having a housing (2, 3) which has a fluid inlet chamber (8), a fluid outlet chamber (9) and a closing body (4a) reciprocable between a blocking state and a release state, wherein the fluid inlet chamber (8) and the fluid outlet chamber (9) are separated from each other in the blocking state and communicate with each other in fluid-conducting relationship in the release state. In particular it is proposed that the evaluation unit is connected in signal-conducting relationship to one or more actuators, and is adapted to control the actuator or actuators by the control commands, wherein the alarm valve station preferably has one or more sensors and the evaluation unit is connected in signal-conducting relationship to the sensor or sensors and is adapted to control the actuator or actuators in dependence on the sensor data present thereat.
