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.


What is reverse acting solenoid valve?

A reverse acting solenoid valve is a type of valve that operates in the opposite manner of a standard solenoid valve. In this configuration, when electrical current is applied to the solenoid, it causes the valve to close instead of open, and vice versa when the current is removed. This design is often used in applications requiring fail-safe operations, where the valve should default to a closed position in the absence of power. Reverse acting solenoid valves are commonly found in systems such as HVAC, fluid control, and industrial automation.


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.


When would you use a solenoid valve?

A solenoid valve is used when you need to control the flow of liquids or gases automatically and remotely, typically in applications involving automation, irrigation systems, or HVAC systems. It is ideal for situations where quick response times are required, such as turning on or off fluid flow in response to electrical signals. Additionally, solenoid valves are beneficial in applications that require precise control and safety, such as in industrial processes or water management systems.


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.


What is yoke mounted solenoid valve?

A yoke-mounted solenoid valve is a type of valve that uses an electromagnetic solenoid to control fluid flow, typically in industrial applications. The "yoke" refers to the structural component that supports the solenoid and connects it to the valve body, allowing for efficient operation and alignment. This design facilitates easy installation and maintenance while ensuring reliable performance in various fluid handling systems. Yoke-mounted solenoid valves are commonly used in automation, irrigation, and process control applications.


Does a solenoid valve leak refrigerant?

A solenoid valve itself should not leak refrigerant if it is functioning properly and is well-maintained. However, if the valve is damaged, worn out, or improperly installed, it can develop leaks at the seals or connections. Regular inspections and maintenance are crucial to ensure that solenoid valves operate effectively without leaking refrigerant. If a leak is detected, the valve should be repaired or replaced promptly to prevent refrigerant loss.
