摘要： The present invention addresses to a device that allows the control of the gas pressure at the outlet of a fixed bed adsorption equipment operated at high pressures, by means of the actuation of a micrometric valve (6), wherein the valve must be located downstream of the equipment. The valve actuation takes place by means of a stepper motor (1), controlled by a microcontroller board (22), which connects to the valve shaft by means of a system of pulleys (2, 5) and belt (3). The present invention is applied in adsorption units, in which other gases are present, by altering the tuning parameters of the PID controller or even being used in a liquid medium or gas-liquid two-phase flow.

摘要： In various implementations, a manual actuator may be coupled to a valve to provide the ability to shut off anhydrous ammonia flow through the valve remotely (e.g., in emergencies). The valve may be coupled to anhydrous ammonia tanks, such as nurse tanks and/or storage tanks. The manual actuator may include manual release member, a breakaway member, a handle, and pull cord(s). The handle may allow a coupled valve to be opened and/or closed. The handle may allow the valve to be shut off at the valve, in some implementations. The pull cord(s) may allow a coupled valve to be remotely closed.

摘要： A sub-surface safety valve having a positional flapper, a valve seat, and a remotely actionable opening prong. The opening prong comprising at least one of a debris wiper, filter, and at least one flow hole. The wiper, filter, and at least one flow hole function according to either position or movement of the flapper and opening prong and prevent debris buildup around the valve seat. The wiper is an extendible material in communication with the valve seat and a surface of the opening prong and it extends radially in response to closing the valve. The extension of the wiper in response to closing the flapper cause the wiper to scrape the surface of the valve seat. The filter can comprise a screen integrated with or attached to the opening prong. The flow holes can be in the form of angled flow holes or elongated slots.

摘要： Provided is an enclosure with an integrated hydrant. The enclosure includes a fluid flow conduit that transfers fluid from a fluid supply tube to a fluid outlet, which may be associated with the backflow preventer. The enclosure has a conduit that carries water from the fluid supply tube to the backflow preventer. Thus, a lower profile, lighter, and more aesthetically pleasing enclosure is provided.

摘要： A valve assembly for controlling flow of water to a shower head includes a tube, which is insertable between and attachable to an inlet pipe for a shower enclosure and a shower head. A valve positioned in the tube regulates a flow of water through the tube. A shaft is attached the valve and extends through a sidewall of the tube and a housing. A biaser positioned in the housing is operationally engaged to the shaft and biases the valve to an open configuration. A lever arm is attached to and extends from the shaft. A handle is attached to the lever arm distal from the shaft. The handle can be moved by a user from a first position to a second position, thus actuating the biaser to rotate the valve from a closed configuration to the open configuration so that water flows through the tube to the shower head.

摘要： Provided is an actuator including: a casing; and a cable driving part including a rotation member connected to a cable. The cable driving part moves the cable forward and backward by rotating the rotation member with a force of a motor based on an operation signal. The cable extends from a water flow direction changing part and is inserted into the casing. The water flow direction changing part changes a direction of a water flow to be ejected. The operation signal is an operation signal for operating the water flow direction changing part.

摘要： In various implementations, an electronic actuator may be coupled to a valve to provide the ability to shut off anhydrous ammonia flow through the valve (e.g., in emergencies). The valve may be coupled to anhydrous ammonia tanks, such as nurse tanks and/or storage tanks. The electronic actuator may include a handle and a bracket. The handle and the bracket may include at least two attractive components that are magnetically attracted to each other upon application of an electric current and the valve may be open. When the electric current is cut, the attractive components of the handle and the bracket may not be magnetically attracted to each other and the valve may be shut off. A controller (e.g., a switch) may be coupled to the electronic actuator to allow control of the electric signal to the electronic actuator.
