The stop valve (3) is a rotary valve controlled by a hand wheel (6) which can be rotated by a user to move the stop valve (3) between open and closed positions.
The controller (12) closes or opens the stop valve (9) instantaneously, and the section (11) calculates the flow rate when the stop valve (9) is closed.
The automatic cut-off apparatus (1) is formed by the combination of a bi-directional negative pressure stop valve (1-2), a stop valve protecting hood (1-3) and a Murphy tube (1-1).
According to the invention, the stop valve (10) is provided with a closing element (20) having a valve lifter (24).
The controllability of the stop valve can thus be improved.
The aim of the invention is to provide such a shut-off valve which has a flow resistance that is as low as possible in the open position of the valve element as a result of the design of the shut-off valve.
The shut-off valve (10) comprises a diaphragm valve and a pilot valve (30).
Thus a separate shut-off valve is not required.
The control valve subsystem includes a feed water shut-off valve (10) and a regulating valve (30).
A flashback-arresting shut-off valve is disclosed herein.
There is also a cut off valve (60) provided to cut off the supply of cleaning fluid from the canister (62) when the device is not in use.
A second shut off valve is coupled to the second nozzle.
The said second precision hole extended further to the manifold out let provided with thermal shut off valve 10.
The gaseous fuel shut off valve is thereafter opened while the engine is operating in the liquid fuel mode.
The dispensing device is characterized by use of a shut off valve mechanism or a twist lock mechanism or a spring valve mechanism for dispensing the liquid.
A shut off valve (160, 200) is provided to prevent oil from passing through the emission control system to the engine.
A ball check valve obviates the need to incorporate additional shut-off elements in conduit systems in which ball check valves are used.
The valve guide acts as a stop for a check valve element that controls communication through the inlet port, and also guides and supports the spring controlling the check valve element.
It is also possible to provide each pressure branch (29, 30) with a check valve.
The liquid dispenser further includes a check valve (34) positioned in the passageway of the valve housing.
A check valve (6) is connected between mechanical brake control (4) and trailer control valve (3).
The cut-off valve (4) has a use as a flow regulator valve for pushing the cut-off valve rod (43) forwards to gradually cut off.
The shutoff valve unit further includes a shutoff valve (81) having a valve body (82) to open/close the valve port (54) and an air-tight main body.
An automatic shutoff valve is provided.
A shut-off flap seat (7) formed by structural elements (2, 3; 8, 12a; 12b) is arranged between the housing (2) and the shut-off flap (3).
The shutoff valve (216) is controlled by a solenoid valve (210) coupled between an air-to-open (ATO) input of the shutoff valve (216) and an air power source (118).
When the hydrogen concentration is less than a reference concentration for opening a valve, an upstream cut-off valve (61) closes and a downstream cut-off valve (62) opens.
The fluid delivery set (11) includes a stop cock valve (19), and the pump (12) includes a valve actuation unit (14) into which the stop cock valve (19) is positioned for operation of the system.
The nozzle is preferably mounted to the stop flow valve.
A pressurised fluid cylinder (2) having a shut-off valve with a linearly moveable valve comprising a valve element (6).
The shut-off valve further comprises a filter portion covering at least a portion of an exterior surface of the valve body.
In the valve assembly, the service connection is designed as part of the shut-off valve and communicates with the condenser side port.
The shut-off valve is disposed between the pressurized reservoir and the at least one pump.
Each shut down valve and sensor is coupled to a production flowline.
A shut-off valve is disposed within the distal end of the syringe body.
.4 Each section of sprinklers shall be capable of being isolated by one stop valve only.
