What's New
3/4 Way Solenoids
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!
Coaxial Cryogenic Solenoids
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!
Latching Cryogenic Service Valves
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.
Fast Acting Valves Deliver Performance On Demand
Shortly after ringing in the new year, the team at CEI buckled down to deliver their first products of the year: 4 shiny, new sleeve valves were delivered to Pratt & Whitney Rocketdyne at the end of January.
The project began in April 2010 when CEI met with engineers from PWR to discuss the possible application for the sleeve technology. Preliminary design work was completed in July, and the ball continued to roll as a contract finally arrived a month later. Soon after, CEI partnered with long-time subcontractor Project 14 to perform manufacturing and process development work for the contract. The partnership proved fruitful as a preliminary test, performed in early December, validated the valve design.
A major requirement of the program, and a primary reason that CEI valves were chosen, was a hefty response time specification. Each valve had to move from closed to full open in less that 80 milliseconds. There was uncertainty on this facet throughout the program, but CEI's trusted engineering was validated again when the test valve far outperformed expectations, opening in less than half the required time!
Both parties have met in consideration of continuing use of this design concept for the future of PWR's program, but no contract has been awarded for such work as of yet.
