Tips To Selecting A Solenoid Valve
In selecting a solenoid valve, it is imperative to deliberate duration of response as well as duration of the valve to be energized.
Solenoid valve is used for controlling the flow of liquid or gas/air powered tools motors, and systems. It functions as an electromechanical device initiating a current to run through a coil in the valve. The flow of current causes the formation of a magnetic field which brings about the displacement of a metal actuator.
In fluid logic, this type of control valve is mostly utilized to shut off, discharge, dose, allocate or combine fluids. These valves may be found in a lot of areas of application. These types of valves provide rapid as well as risk-free switching, increased dependability and long term duration of service, excellent medium compatibility of materials, decreased control power, and efficient construct. These valves may also make use of rubber or metal seals as well as include electrical interfaces to facilitate ease of control. When the valve is not turned on, a spring may be used in keeping the valve either closed or opened.
In selecting a solenoid valve, it is imperative to deliberate duration of response as well as duration of the valve to be energized. Nonstop total duty valves of this type are most favorable for repeated on and off cycling. Select normally close valve or normally open valve contingent to the position the valve is expected to be in majority of the time.
To decide on the suitable solenoid valve, make a comparison of all the specifications of the valve with the process being regulated. The highest limit of operating pressure differential must be assured to be equal or more than the pressure aligned to which the valve has to operate. Take account of these guidelines.
1. Identify the appropriate types of solenoid valves. More information on types of a solenoid valve to have a more comprehensive data for each.
Direct-acting valve - With magnetic force acts directly on its sealing mechanism, raising the shaft and the base of the valve devoid of external pressure.
Pilot operated valve - Accumulated pressure brings about either the opening or closing of the valve at the same time the plunger opens the pilot opening. It necessitates less electrical power to work.
2 Way valve - The ports of this valve are used interchangeably to facilitate opening or closing the valve. It can either be indicated as normally open valve or normally closed valve in its function. Normally closed solenoid valve is used majority of the time, operating in the opposite manner, keeping closed awaiting an activating source to open it.
3 Way valve - This type of control valve has three ports. As alternate pressure and exhaustive pressure are needed for working tools or appliances, this three way valve is frequently used.
4 Way valve - Evidently, this valve includes four ports. It is either specified as normally open, normally closed, or universal. This is used along with a dual acting cylinder or actuator. Two of the ports provide pressure while the rest exhaust pressure.
2. Obtain as much information about the valve of choice as possible including specifications on the valve, manufacturer, and model number.
