A squib is a small explosive charge, and a squib actuated valve is one that uses such a small charge to effect rapid operation of the valve to either open (the usual case) or to close. These valves are used, for example, in fire suppression systems, and in devices such as torpedoes to initiate rapid start up of the propulsion system.

What is a water Toby?
A water Toby is a shut valve at a water main
How is mitral commissurotomy performed?
The commissures--openings between the valve leaflets--are manually separated by the surgeon.
What are the valve lash specs on H farmall 1942 ser106300?
Valve lash specs on the H Farmall 1942 Serial number 106300 refer to the tune up specifications for that particular tractor. On some varieties, the point gap is .020 and on some the timing mark is on MP.
What did reginald clinker invent?
Something ??. He invented Almost Perpetual Motion - The Amazing Clinker Pendulum Clock held in the science museum London. 1912 Mr Clinker built a crystal set capable of picking up the Morse time signals from Paris, and from then on, the Works clocks were synchronised with the Eiffel Tower international time signals. He became a pioneer in the development of radio valves, making in 1915, what is reputed to be the first British hard vacuum valve. After the war he invented and designed a portable 2 valve receiver, with self-contained aerial, to replace the crystal set used to pick up the time signals.
Why two solenoid valves are required for on-off valve?
Some times on/off valves are to large to be actuated using one solenoid valve,but most of the on/off valves are being actuated using only one solenoid valve
Is normally open valve and fail open valve the same?
"Normally Open" or "Normally Closed" are classifications that refer to actuated (not manually operated) valves. For an actuated valve, the "normal" state refers to its position when the actuator is not energized.Therefore a normally open valve is one that is open until the actuator is energized to close it; if power to the actuator fails, the valve opens or "fails open".Likewise with a normally closed valve if power to the actuator fails, the valve closes or "fails closed".The "normal" state of an actuated valve must not be confused with the "usual" position of the valve during routine operation of the system. A normally closed valve may be open continuously over a long period of time while a process is running, but it is still a normally closed valve. It just happens that this normally closed valve is usually open.For an actuated valve to return to its "normal" position, there must be some force, often a spring, that moves the valve from its actuated state back to its normal state. If a valve is actuated to open and then actuated to close, it will "fail" in whichever position it is in when the activator is de-energized. This type of a valve is not considered "fail safe".A normally closed valve might be used in an application such as the loading of gasoline transport trucks where in the event of a power or automation system failure, you would want to stop flow.A normally open valve might be used in a situation where you want flow to continue in the event of a power or automation system failure. This might be the case for the cooling water system for a nuclear reactor or for an actuated valve on the water piping to the fire protection system.
What is a VW combi valve?
A combination valve is a pneumatically actuated shut-off valve. It is integrated into a valve housing and is typically used for blocking and releasing a flow between an inlet and an outlet
On a 78 Chevy truck does the heat riser have a Donut?
If it has the bi-metal spring actuated valve it has a donut. If it has a vacuum operated valve it has no donut.
What is the difference between SDV and ESDV?
The construction and accessories of Shutdown Valve (SDV) and Emergency Shutdown Valve (ESDV) are similar. What is the basis to distinguish their name? Their name is distinguished only from their services. Shutdown Valve referred to actuated valve which is closed during partial or total process shutdown of system to which the valve protects. Emergency Shutdown Valve is actuated valve which is closed when triggered by signal from ESD level signal during emergency condition occurs. Emergency Shutdown Valves are commonly located in incoming line and outgoing line of the plant or platform.
What is the use of electric actuated shut off valve?
Means you can shut it off from a distance. Useful either in an automatic system or if you don't want to have someone being around the valve when it's time to shut it off.
What happens if the air pressure is lost from the primary brakes system?
The treadle (foot valve) moves downwards until the secondary air system can be actuated mechanically.
What does the heater valve do?
The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced
What is the purpose of the pushrod?
The pushrod is actuated by the camshaft for the purpose of actuating the lifters/rocker arms which, in turn, pushes open either an intake or exhaust valve in the cylinder head.
Zone valve is used to open in hot water heat?
A zone valve is actuated by a thermostat and will allow water to pass from the boiler to radiant floor piping or base board radiators or in some cases a hot water storage tank.
What is a pneumatic solenoid operated spool valve?
spool valveA spool valve is a multidirectional hydraulic or pneumatic valve usually operated by a joystick. It has several hoses attached to it leading to different pneumatic rams. When the joystick is pushed in one direction, it causes the valve to shut off one of the pneumatic hoses leading to the ram and open the other. Which way the joystick is pushed moves the piston in the ram in or out. Since you specified a solenoid operated valve it is operated not by a joystick that is directly connected to the valve but rather an electric joystick like the you would use in a video game and an electrical signal is sent to activate a solenoid that does the same thing but can be much farther away from the operator. Solenoid Actuated Pneumatic Spool ValveA solenoid actuated pneumatic spool valve is a spool valve actuated by an electric solenoid. They are often used in industrial automation and are usually controlled by a PC or a PLC (Programmable Logic Controller) rather than a manual switch. To reduce the size and power consumption of the solenoid, often the solenoid does not directly actuate the spool. Instead, the solenoid actuates a small internal valve which directs upstream air pressure to move the spool. This is called an air piloted solenoid actuated pneumatic spool valve. The air pilot mechanism typically requires about 40 PSI to operate reliably. If the air pressure upstream of the valve is going to be less than 40 PSI, the valve must be externally piloted, meaning that the pilot is connected to a separate air source which is above 40 PSI.
Where is the EGR Valve in a Ford F-250?
They are usually on the valve cover. Trace the hoses from the carb since they are vacum actuated. 1 of those should lead you right to it. If you shake it & there is movement inside, it is good.Amendment - by PayDayBillThe PCV Valve is located in the valve cover not the EGR. The EGR valve is located on a spacer block that is installed between the Carburetor and the Intake Manifold. It points to the back side of the engine behind the carb. The EGR will be visible once the air cleaner assembly is removed.
