A temperature-controlling water valve is provided. An adjusting assembly is assembled within the water valve and includes an adjusting member, a first elastic member, a blocking member and an abutting member. The first elastic member biases the abutting member, and the blocking member is fixed to the adjusting member to block the abutting member from detaching from a receiving hole of the adjusting member. A temperature-controlling assembly includes a valve member and a second elastic member biasing the valve member. Thermal expansion or contraction of a rod member of the valve member drives the valve member to move so that an overlapping area of the valve member and a first passageway of the water valve and an overlapping area of the valve member and a second passageway of the water valve change.

A valve closing member for cooperating with a valve seat, comprising: a body a front circular face forming a central protrusion along a longitudinal axis of the body; a seal forming a ring fitted on the front circular face and around the central protrusion; and a retainer forming a ring surrounding the seal and attached to the body for retaining the seal on the body; wherein the seal shows a radially inner surface contacting a radially outer surface of the central protrusion, the radially inner surface and radially outer surface being both cylindrical, the radially outer surface showing at least one circular groove into which the seal is radially pressed by the retainer.

A safety release bleeder valve serving as a plug includes a barrel having an exterior surface and an interior throughbore surface for matingly receiving a plug having a top end with exterior threads and an interior socket for receiving a driver tool for moving the plug between an open venting state and a closed non-venting state.

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted to allow the body to move between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section

A pressure evacuation device for a compressed gas cylinder having a fixed assembly that is semi-permanently attached to an opening in the cylinder and comprises a retractable bleed valve, and a detachable assembly that can he readily attached to and detached from the fixed assembly and comprises a valve stem to control the bleed valve and a valve tee to direct the flow of gas from the cylinder.

The invention is directed to a valve actuating device comprising a body with a bore and a bottom, an actuating element sealingly housed in the bore of the body and forming a first chamber with the body, a piston sealingly extending through a bore in the actuating element, the piston and bore delimiting a second actuating chamber, a passage for an auxiliary fluid between the first and second chambers so that a movement of the piston in the bore of the actuating member can increase the pressure in the first chamber and move the actuating element. The fluid passage comprises a restriction and a check-valve, both arranged in parallel, so as to limit the flow of the auxiliary fluid from the second chamber to the first chamber.

A valve mechanism includes a first plunger, a second plunger, a seal member, and a valve element. The first plunger has a thread engaging with a threaded portion provided on an inner wall of the flow passage. The first plunger is movable along the axis by rotating around the axis. The second plunger has a first end and a second end. The first end engages with the first plunger such that the first plunger is relatively rotatable with respect to the second plunger. The second plunger is movable along the axis by rotating the first plunger. The seal member is provided to surround the second plunger. The valve element has a back end engaging with the second end such that the valve element is movable along the axis according to movement of the second plunger so as to be seated on and separated from a valve seat.

Provided is a valve for high-pressure gas, wherein a sheet member is provided inside a through hole formed in a valve body of the valve, wherein the sheet member constitutes a channel for high-pressure gas inside the through hole, wherein the sheet member is fixed inside the through hole by a pressing member, wherein an end opening of the through hole is closed by a lid member, wherein a gasket is provided at a peripheral part of the end opening of the through hole, wherein the gasket is sandwiched between the lid member and the valve body, wherein the lid member is pressed toward the valve body by a plug, and wherein a bearing is provided between the plug and the lid member.

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted with the ability to move on the body between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section.
