They are known for their long life and fast response time. The solenoid is an electromagnetic part of a valve, comprised of a coil, core tube, core and enclosure. ASCO's 2-Way solenoid valves have one inlet and one outlet, and are used to permit and shut off fluid flow.

Two types of constructions apply to 2-way solenoid valves, which are direct acting and internally piloted. With Direct acting constructions, the solenoid is energized, the core directly opens the orifice of a Normally Closed valve or closes the orifice in a Normally Open Valve.

The valve will operate at pressures from 0 psi to its rated maximum. Internally piloted constructions use line pressure to assist operation. When the coil is de-energized on a Normally Closed Valvethe pilot orifice is closed and line pressure is applied to the top of the piston or diaphragm through the bleed orifice, closing the valve. When one orifice is open, the other is closed and vice versa.

They are commonly used to alternately apply pressure to an exhaust pressure from a valve actuator or a single acting cylinder. These valves can be normally closed, normally open or universal. One pressure inlet, two cylinder ports providing pressure to the double acting cylinder or actuator and one or two outlets to exhaust pressure from the cylinders.

Solenoid Valves

Here are some tips. There are four symptoms that indicate a solenoid valve is malfunctioning. They include: 1. Failure to open; 2. Failure to close; 3. Internal or external leakage; and 4. Creating noise when energized. So what causes these ailments? Follow this technical advice for diagnosing symptoms of an unhealthy solenoid valve and treating it properly for a quick recovery.

Symptom: valve won't open When energized, a normally closed solenoid valve opens see Figures 3 and 4.

When the solenoid is energized, the plunger strikes the pole piece with an audible "click. Diagnosis: Electrical or mechanical failure. Remedy: First, be sure that there is a completed electrical circuit. If proper voltage is measured at the coil and you still don't hear a click, then a mechanical obstruction is preventing the plunger from moving.

The obstruction may be caused by overpressurization, dirt, or worn components. Next, check the pressure at the valve inlet to ensure that it doesn't exceed the maximum operating pressure differential MOPD as rated on the valve's nameplate. If dirt is present in the system, disassemble and clean the valve and install a suitable filter upstream from the valve.

Important : Remember to evacuate the system or isolate the valve from the system's refrigerant before disassembling. Also, it's important to replace worn components with the correct manufacturer's rebuild kit. Pilot-operated diaphragm or piston valves may fail to open if system pressure is below the minimum pressure differential requirement stated on the valve's nameplate.

In addition, if the diaphragm or piston pilot orifice which controls the opening of the valve is blocked by dirt or debris, pressure will remain above the diaphragm or piston, and the valve will not open. The pilot orifice in offset pilot valves is located in the valve body, directly below the plunger.

A torn diaphragm also allows too much pressure above the diaphragm, causing it to remain closed. Symptom: valve won't close Diagnosis: Electrical or mechanical failure. Remedy: When a de-energized valve won't close, again, check the electrical circuit to ensure that power is disconnected from the coil. Mechanical causes that inhibit movement of the plunger, including a missing or damaged plunger return spring, may not allow the plunger to seal off the main orifice or pilot orifice.

In the case of pilot-operated diaphragm or piston valves, a blocked bleed orifice can cause the valve to remain open. When encountering "failure-to-close" characteristics, it is important to know whether the valve isn't closing at all, or if it is attempting to close but doesn't close completely because of internal seat leakage.

In the case of internal seat leakage, other causes should be considered. Symptom: valve won't open normally open Diagnosis: When a normally open, de-energized valve won't open, it's an electrical or mechanical failure. Remedy: A normally open valve should open when it's de-energized. If it doesn't, overpressurization, dirt, or worn components may be at fault. In this case, check the electrical circuit to ensure that power has been disconnected from the coil.

Symptom: valve won't close normally open Diagnosis: The bleed orifice controls the closing for the energized valve and, if blocked, will not allow pressure to flow above the dia-phragm or piston, enabling them to close the valve.

Remedy: A normally open valve should close when energized. Similar electrical causes to those identified under the "fails to open when energized" category should be considered.

Additionally, when examining pilot-operated diaphragm or piston valves, the bleed orifice in the diaphragm or piston should be inspected.
