The piston plug is movable between a closed position in which the piston plug is seated against the guide seat and engaged with the valve stem to prevent fluid flow through the valve, a metering position in which the piston plug is moved away from the guide seat and engaged with the valve stem to enable a predetermined amount of forward fluid flow through the valve, and a check valve position in which the piston plug is seated against the guide seat to prevent reverse fluid flow through the valve.

A sanitary fitting, more particularly a thermostatic mixing valve, includes a housing, which has a valve seat for receiving a valve and into which at least one feed channel and a discharge channel open, wherein the at least one feed channel is led through a chamber, into which a backflow preventer is inserted and which is closed by a plug. A retaining frame is provided on the plug, which retaining frame protrudes into the chamber and by which retaining frame the backflow preventer is axially fixed.

A water delivery valve assembly includes a cold water inlet and a hot water inlet and a mixed water outlet, a mixer valve assembly configured to receive water from the hot and cold water inlets in a ratio determined by a desired temperature input and to mix the hot and cold water in a mixing chamber, and a flow control valve assembly sharing a common housing with the mixer valve assembly and arranged to receive water from the mixing chamber and provide water at the desired temperature to the mixed water outlet at desired time period. The mixer valve assembly includes drive means to control the ratio, and the flow control valve includes drive means to control the flow, and the drive means of the mixer valve assembly and of the flow control valve assembly are also provided in the common housing.

A high-pressure gas cylinder valve for vehicle includes a valve seat having a gas charging runner and a gas supplying runner. A check valve is connected in series onto the gas charging runner, and the check valve and a solenoid valve are connected in series sequentially onto the gas supplying runner in a gas flow direction. A portion of the gas supplying runner located downstream of the solenoid valve is jointly connected to a portion of the gas charging runner adjacent to a gas inlet end and supplies gas to outside through a gas inlet of the gas charging runner when the gas supplying runner supplies gas. The gas cylinder valve further includes a flow-blocking buffer structure connected in series onto the gas supplying runner and located downstream of the solenoid valve and upstream of an intersection of the gas supplying runner and the gas charging runner.

Disclosed is a capacity control valve includes a valve housing. A main valve including a valve body is driven by a solenoid, and a main valve seat which is between a discharge port and a control port and with which the valve body can contact, a pressure sensitive valve member forms a pressure sensitive valve, together with a pressure sensitive body disposed in a pressure sensitive chamber. The control port and a suction port communicate with each other through an intermediate communication passage by opening and closing of the pressure sensitive valve. The pressure sensitive valve member has a through-hole communicating with the intermediate communication passage, and has an opening and closing member attached thereto such that the opening and closing member is restricted in movement with respect to the valve housing by restriction device and slides relative to the pressure sensitive valve member to open and close the through-hole.

There is provided a capacity control valve having a fluid discharge function at a start-up and having good operating efficiency. A capacity control valve V includes a valve housing 10; a main valve 50 including a valve body 51 driven by a solenoid 80, and a main valve seat 10a which is provided between a discharge port 12 and a control port 14 and with which the valve body 51 is contactable; and a pressure sensitive valve member 52 disposed in a pressure sensitive chamber 40 and forming a pressure sensitive valve 53, together with a pressure sensitive body 60. The control port 14 and a suction port 13 are allowed to communicate with each other through an intermediate communication passage 55 by opening the pressure sensitive valve 53. The pressure sensitive valve member 52 is provided with a through-hole 52d communicating with the intermediate communication passage 55 and has a slide valve body 90 attached thereto such that the slide valve body 90 slides relative to the pressure sensitive valve member 52 to open and close the through-hole 52d. A biasing device 91 that biases the slide valve body 90 in an opening direction is provided on a radially outer side of the slide valve body 90.

The present disclosure discloses an electromagnetic regulating valve with a check function. The valve may effectively regulate the flow in a valve body. Due to different lengths and taper angles of a valve flap group, the flow can be regulated more finely, and a medium can be prevented from backflow by a check function when necessary. Meanwhile, a mesh structure of bases of valve flaps can effectively reduce the instability of flow field motion so as to achieve an effect of rectifying.
