Each and every product CEI produces is custom engineered to exact specifications. Whatever the application, whatever the envelope, CEI products are designed to withstand and deliver. CEI offers several different product lines to suit any needs you have for pneumatic controls.
  • Solenoids   ( 3 Articles )

    Castor solenoid actuated valves are incredibly versatile. Built for every purpose, from micro-vernier thrusting applications to four way control of cryogenic liquids, our solenoids get the job done when others can't.

    We use only aerospace grade materials in every part, and control every point of the manufacturing process to ensure that you get the very best in electromechanical control technology EVERY time.

  • Sleeve Valves   ( 1 Article )

    CEI sleeve valves are the pinnacle of performance and innovation in minimal-obstruction flow control valves. These valves achieve flow rates comparable to open flow path valves, while maintaining a physical diametric envelope that is often less than 1.5 times actual line size. Compare with motor actuated ball valves of similar line size! All sizes are available in the pilot open/close configuration, as well as pilot open/spring closed.

Quick Stories

  • Latching Cryogenic Service Valves
  • Coaxial Cryogenic Solenoids
  • 3/4 Way Solenoids

Castor Engineering Inc. is pleased to announce the arrival of our latest product, the 100222 Latching Solenoid Actuated Valve. The 100222 is primed and ready for gaseous and cryogenic liquid media for pressures from 0-1500 PSIA. Based upon an older model known as the 'frictionless solenoid,' for it's lack of piston (friction) seals, this valve features a double seat configuration. This configuration removes the need for expensive special spring loaded seals that have proven to be less reliable than standard o-rings.

Coaxial solenoid valves are the perfect fit for small line size, small envelope, and low pressure applications. Our valves are custom built, and assembled by hand. This ensures that you get a top quality valve, most with duty cycles in excess of 10,000 cycles. We also offer soft goods kits for these (and other) valves. Once refurbished, they're good to go for another 10,000+ cycles!

CEI also offers a line of 2,3, and 4 port directional solenoid valves, offering you even greater versatility with your system's design. The beauty of the multi-directional solenoid is that it can combine the functions of two or even three valves into one simple package!

Perfection in Motion

Here at Castor Engineering Inc., we strive for one thing: to bring our customers that absolute best controls and systems that can be made. It takes skills, know-how, and a lot of patience. But we feel that without these characteristics, our valves would be just another commodity on the market. When it absolutely HAS TO WORK, we pride ourselves on being the folks you'll call.
