Cartridge: These are the most commonly manufactured RAM Company solenoid valve design.
This type pf valve lends itself to simplicity and high efficiencies. Designs are available in two or three way flow as well as direct
or pilot operated. Pneumatic solenoid valves can be designed up to operating pressures of 10,000 psig. Hydraulic solenoid valves
can be designed to yield flow rates of up to 20 gallons/minute.
Applications are numerous! This type of solenoid valve can be found in many hydraulic and fuel systems.
Cartridge type solenoid valve features include the following:
• Fluids MIL-PRF-5606, MIL-PRF-83282
• MIL-C-7024 calibration fluid
• 2 way, 3 way, 4 way
• Operating pressures from 0 to 5000 psig
• Proof pressures from 0 to 7500 psig
• Flow rates from 0 to 20 gpm
Other design options include:
• 2 to 4 coil redundancy
• Latching, magnetic or mechanical
• Over molded coils
• Rubber molded poppets
Butterfly: RAM Company rotary Butterfly Valves utilize the unique benefits of the RAM Company rotary solenoid,
integrated with a valve body for excellent operational performance. Without the corkscrew motion that other rotary solenoid designs yield,
RAM Company rotary butterfly valves use less components which translate into longer life, quicker response times and better repeatability
throughout the life of the valve. Butterfly valves can be designed as either normally-open or normally-closed in the de-energized position.
Ram Company rotary butterfly valves are commonly used on low pressure bleed air applications.
Features of the Rotary Butterfly design include the following:
• Sizes from 1" to 3" diameter
• Operating pressures from 0 to 10 psig
• Normally open or closed
• Low pressure drop
• Corrosive environments
Applications: Listed below is just a small sampling of the literally thousands of different linear solenoid applications:
Land: The M1/A2 Abrams Tank, and the the EFV Expeditionary Fighting Vehicle both utilize RAM Company designed
solenoid valves for environmental control in the cabin. The Paladin SPH utilizes Ram Company solenoid valves for control of the
hydraulic systems.
Air: A large variety of RAM Company solenoid valves are utilized for aerospace applications.
With applications on various models of Boeing aircraft, to the mid-size Embraer 170/190, and including such regional jets such
as the Premier One and Hawker Horizon, RAM Company is well established as a supplier of innovative, well-designed products.
In addition to the many commercial aircraft applications, RAM Company solenoid valves can be found on a variety of military aircraft,
such as the C17, F15, F22, JSF, and the Black Hawk helicopter. Various types of solenoid valves are commonly used for aileron systems,
flap and landing gear control, fuel control, and bleed air.
Space: A solenoid powered butterfly valve is used in the water purification system on the International Space Station.
Sea: RAM Company builds solenoid valves for a variety of undersea applications.
