Two Way Valves
Two-way valves have one inlet and outlet pipe connection. These will help you for normally open and closed operations. Normally opened valves are open when the coil is de-energized and close when the coil is energized. Normally closed valves are closed when the valve is de-energized and open when the proper voltage is applied to the coil.
Three Way Valves
Three way valves are designed with three pipe connections and two orifices which are alternatively opened or closed. These ASCO valves are available for normally closed, open or with universal construction that is used as normally closed or normally open. Three way ASCO Red Hat Solenoid valves are mainly used as pilots for larger control valves to actuate single-acting cylinders or to divert the flow of fluids.
Four Way Valves
These valves have four pipe connections. One for exhaust, one for pressure and two for operating double-acting cylinders. Four way valves are used to pilot larger control valves.

Manual Reset Valves
Manual reset valves will be closed or opened manually and then revert to their original position when they are energized or de-energized. These are used for preventing the inadvertent startup of critical systems.
After determining the basic ASCO solenoid valve type, while selecting, you should consider pipe size including flow rate, orifice size, pressure rating, ambient & fluid temperatures, medium to be controlled, type of solenoid enclosure, voltage, cycling rate and required life rating. Each factor's importance needed to be determined by the application itself.
ASCO Red Hat Valve Installation and Maintenance
To increase the valve life, you should install and maintain it properly. However, you need to read and follow the instructions given on the red hat and red hat II valve for each model.
You must check the nameplate data for voltage, pressure, etc. to ensure compatibility with your system conditions. Moreover, you have to know that the solenoid enclosure type with your operating conditions.
Some red hat valves will operate in any mounting position, while others have to be mounted in a certain way to operate correctly. However, it's better to install these valves with the solenoid in a vertical upright position. If you install the valve in a vertical upright position, there will be less chance of foreign matter accumulation in the core tube area. You need to install the filter or strainer as close as possible to the red hat valve inlet.
The wiring should have complied with the local codes and the Canadian Electrical Code. Make sure you don't pull out from the coil. If you are not using a flexible conduit for transition into the valve, the supply conduit should support properly to reduce stress on the solenoid assembly.

You must clean filters and strainers on regular basis along with cleaning and inspection of the valve to prevent malfunctions.
If you want to disassemble the valve, you need to follow the disassembly instructions which are given with the valve. Foreign matter in the red hat valve like corrosion from pipes & process vessels, mineral deposits, pipe joint sealant and other solids is the major cause of solenoid valve failure.
You must use two wrenches for installing or removing the ASCO solenoid valve.
With a lint-free cloth, wipe off dirt on the ASCO red hat valve body.
The core of the solenoid should be moved freely in the core tube. Also, it should be free from binding and excessive wear deposits signs.
You have to check the disc at the end of the movable core for excessive impact. To protect the pipes and equipment from water hammer condition, install the water hammer cushion close to the valve inlet.
Hope you got an idea about ASCO Red Hat Solenoid Valve and your job might be done easier to select the appropriate ASCO Red Hat Valve and installing. For further more information on the ASCO Red Hat II Solenoid Valve, you can refer to the valve manual. Moreover, PartsAPS offers ASCO solenoid valves so you can buy here if you need them.
