Sporlan solenoid valve
Purpose
The primary purpose of an electrically operated sole-noid valve is to control automatically the flow of fluids,liquid, or gas. Sporlan Solenoid Valves may be applied on a wide variety of applications.
Basic Types
There are two basic types of solenoid valves. The most common is the normally-closed type, in which the valve opens when the coil is energized, and closes
when the coil is de-energized. The other type is the normally-open valve which opens when the coil is de-energized and closes when the coil is energized. The operation of both types is discussed in the following paragraphs.
Principles of Operation
Solenoid valve operation is based on the theory of the electromagnet. The solenoid valve coil sets up a magnetic field when electrical current is flowing
through it. If a magnetic metal, such as iron or steel, is introduced into the magnetic field, the pull of the field will raise the metal and center it in the hollow core of the coil. By attaching a stem to the magnetic metal or plunger, this principle is used to open the port of the valve. When the electrical circuit to the coil is broken, the magnetic field will collapse and the stem and plunger either will fall by gravity or be pushed down by the kick off spring. Some solenoid valves are designed with a hammer blow effect. When the coil is energized, the plunger starts upward before the stem. The plunger then picks up the stem by making contact with a collar at the top. The momentum of the plunger assists in opening the valve against the unbalanced pressure across the port. Solenoid valves are also classified according to the U°stem and plungerU± action. The two types are discussed in the following sections.
Direct Acting Solenoid Valves
With this type of valve, the stem and plunger assembly opens the port of the valve directly. This type of construction is limited to the smaller valves with port
sizes of less than 1/4 inch. Sporlan Solenoid Valves of this design are the Types A3, E3, MA5A3, 180 Solenoid Pilot Control and W3P1. Pilot Operated
Normally Closed Solenoid Valves In a pilot operated valve, the stem and plunger assembly opens a pilot port. This releases the pressure on top of the disc, piston or diaphragm which then moves upward and opens the main valve port. Figure 3 illustrates the four phases of the operating cycle of a typical pilot operated valve. The operation is the same whether the valve is a disc, piston or diaphragm type. Initially the pilot port and the main port are closed as shown in A. Pressure at the valve inlet is present on top of the disc as well, because of an equalizer hole drilled through the disc. When the coil is energized, the stem and plunger assembly is lifted and the pilot port is opened UHB. The stem and plunger assembly is centered within the coil by the magnetic field. The pilot port, if properly sized for the fluid to be handled, will relieve the pres-sure on top of the disc. Now the valve inlet pressure will act on a portion of the bottom of the disc, lifting the disc to open the main port UHC. Once the port is open, the disc is held off the seat by the pressure difference across the port. When the coil is de-energized, the stem and plunger assembly drops, due to gravity or the kick off spring, and closes the pilot port. As shown in D the pressure above the disc is no longer vented to the downstream side of the valve. Fluid flow and pressure drop causes the pressure above the disc to be higher than below the disc, and the disc drops, closing the main port. In some valves the plunger is spring loaded and does not rely on gravity to close.
All Sporlan Solenoid Valves except the A3, E3, W3, MA5A3 and 180 SPC are pilot operated and employ either the floating disc, floating piston or floating
diaphragm construction. The pilot operated valves require a very low, 1 psi, pressure differential for full operation.
