For that reason, they are found in many application areas. They are commonly used to shut off, release, dose, distribute or mix fluids. Solenoid valves are the most frequently used control elements in fluidics. By being solenoid actuated, solenoid valves can be positioned in remote locations and may be conveniently controlled by simple electrical switches. An electronically operated solenoid valve is usually used for this purpose. In most flow control applications, it is necessary to start or stop the flow in the circuit to control the fluids in the system. When the solenoid coil is energized in a normally open valve, the plunger seals off the orifice, which in turn prevents flow. Once the solenoid coil is energized, the resultant magnetic field raises the plunger, enabling flow. In normally closed valves, a plunger return spring holds the plunger against the orifice and prevents flow. Solenoid valves consist of a coil, plunger and sleeve assembly. A plunger opens or closes the orifice by raising or lowering within a sleeve tube by energizing the coil. Solenoid valve function involves either opening or closing an orifice in a valve body, which either allows or prevents flow through the valve.
#ELECTRIC SOLENOID VALVE QUOTES MANUAL#
They are often used to replace manual valves or for remote control. How a solenoid valve works is by controlling the flow of liquids or gases in a positive, fully-closed or fully-open mode. They are used in systems requiring low flow capacities or applications with low-pressure differential across the valve orifice. While Direct operated solenoid valves directly open or close the main valve orifice, which is the only flow path in the valve. Their main purpose is to regulate the movement of gas or liquid and eradicate the need for an engineer to manually control the valve, saving time and money. *Consult a chemical compatibility expert for correct seal and valve body material choice.Solenoid valves are electromechanically operated valves that convert electric energy into mechanical energy.
This should not be mounted upside down, with the coil underneath the valve. This model can be mounted vertically or horizontally, and features a conveniently positioned arrow on the body to indication the direction of flow. Its response time is very low in fact, it acts in less than one second, making it a great choice for all types of applications.Ĭustomers commonly use the BZW-25 Valve for Irrigation, Fountains, Water Filtration, Solar Heating, Aquariums, Automotive, Beer Brewing, Hydroponics, HVAC, and Plumbing and everywhere else one of our valves can be applied. The coils are not polarized, which mean that positive/negative does not matter when wiring them. The top of the coil features a label that indicates the valve type and specifications. The coil head is fitted with 5" lead wires that can easily be connected with your own choice of terminals. This specific valve has a 12 Volt DC coil with a voltage range that is -+ 10. This valve works in one direction and will not prevent media from moving backwards in the opposite direction. The seal material is FKM or Viton Rubber.
It can withstand pressure up to 115 psi (8 bar) and temperatures as low as 15☏ and as high as 250☏. The orifice size is 25mm and the Cv value is 12. This Electric Solenoid Valve can handle low viscosity fluids below 20 cst. The port size is 1” inch female NPT threaded. The valve features a heavy duty, solid brass body that’s sure to last in the most strenuous projects. It works across various media such as hot water, air, gas, diesel fuel, Freon, weak acids and weak alkali. Removing the energy from the valve coil will close it and stop the flow. This particular valve is a two-way, semi-direct lift valve with a normally closed operating position. This means that there are two ports in which media flows and the valve will open when the coil is energized to allow media to pass through. Featured here is Model BZW-25 of our brass valve line.
