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

What does a solenoid do on a valve?
A solenoid valve is a type of valve that uses an electrical current to actuate or shift a spool or cartridge consisting of a solenoid coil and tube assembly. Basically, this valve type uses an electric current to shift a pin to perform simple A/B tasks such as open/close valve spools. The designation "solenoid" means that the valve operation is electrical not manual. Maybe the easiest way to describe a solenoid valve is by thinking about an automatic car lock. The electric current get triggered, the pin gets pushed up and the doors are unlocked. A reverse current gets triggered, the pin gets pushed down, and the doors are locked.
In a solenoid valve system if the voltage on the coil is 118 VAC and a continuity test of the solenoid and coil measures 80 ohms yet the solenoid will not allow water flow the most likely cause of?
There could be more than one reasons. Applied voltage may not be 118 volts. Solenoid valve may have been stuck mechanically. Solenoid coil could be faulty, partially short.
What is the advantage of integral starter motorised valves?
Integral stsrters are embedded with motorised valves. By using integral starter, one can control motorised valves by remotely and locally. Even it can indicate the motorised valves direction of rotation & its final position, Power failure detection , indicate motor winding temperature, auto phase correction and emergency shut down of valve.
Difference between boiler mountings and accessories?
Boiler mountings are different fittings and devices which are necessary for the operation and safety of a boiler .e.g. pressure gauge, safety valves , steam stop valve etc Normally these device are mounted over boiler shell .Boiler Accessories are auxilary plants or parts required for steam boilers for their proper operation and to increase efficiency of the boiler .e.g.feed pumps, super heater , economiser etc
If you have a 750 millivolt valve however the thermopile leads only generate 600 mv is that sufficient to open valve?
The voltage spec'd on these units is pretty loose and the valves are desiged to cope with that range. For example, the 750 mv unit at : http://www.honeywellcentral.com/product/0-85267-87879-1.html is rated 600mv to750mv open circuit. Measured in circuit, the output could be even lower than 600mv and be OK .
What type of valve is a solenoid valve?
Solenoid valves are electromechanically operated valves which are controlled by an electric current, mostly used in fluidics. There are different types of solenoid valves, one or two port valves.
What is direct acting solenoid valve?
A direct acting solenoid valve is one in which the action of the solenoid alone switches the valve gate. Most solenoid valves are "piloted", which means that a relatively small solenoid valve is used to allow pressurized air to actuate the valve gate mechanism. Because the solenoid does all of the work in a direct acting valve, the solenoid must therefore be larger than that of a piloted valve in order to generate the switching force. Piloted solenoid valves have the advantage of being more compact and consuming less current than a direct acting solenoid valve. Direct acting solenoid valves are useful when switching low pressure fluids.
What are the different types of electro pneumatics valve?
Electro pneumatic valves are mechanical valves but operated through pneumatic using suitable solenoid coils.
What is the function of pneumatic valves?
If you are talking about a pneumatic solenoid valve the function of it is to control the air in and out flow in a pneumatic actuator.
Difference between a proportional solenoid and a conventional on off solenoid?
1.) in conventional solenoid , the force is not costant...wheras in proportional .it is. 2.) proportional valve fills the gap between conventional and servo valves 3.) proportional valve can take infinite spool positions 4.)proportional valve cannot take high degree if valve performance
From where should you purchase solenoid valve. How is www.valve-store.com?
This is good enough, if you want to purchase general solenoid valves like 2 way, 3 way , 4 way solenoid valves but for generic products you can also serch the manufecturer site as http://www.valve-store.com is a distributer.
Where is a shift solenoid in a 1997 Mitsubishi eclipse?
The shift solenoid on a 1997 Mitsubishi Eclipse is on the back of the valve body. Removing the transmission pan is required to reach the solenoid.
Does a 99 Mitsubishi diamante have an egr solenoid or just the egr valve. If it does have the solenoid where is it related to the valve?
Yes, the Diamante has an EGR solenoid. On any Mitsubishi, if the car has an egr valve, it has a solenoid to operate the valve. Just follow the vacuum line from the valve and it will go to the solenoid. There may be another one way valve between the valve and the solenoid, though. The solenoid is electronic.
Where is the shift solenoid for a 1999 Chrysler 300?
The solenoid are on the valve body inside the transmission.The solenoid are on the valve body inside the transmission.
Which type of solenoid valve used for double acting actuator?
a Three Way Solenoid valve is required to operate a double acting Pneumatic Actuator , depending of the orientation of the Actuator could operate as a Fail to open or Fail to Close .
Do you need a safety valve on an open system?
Safety valves are required on all closed pressure vessels.
