Moog's Servocartridge Valves Offer High Dynamics and Flow Capabilities
EAST AURORA, N.Y. (May 17, 2002) - Moog has introduced into the U.S. market several high dynamic closed-loop cartridge valve products that allow machine builders to make compact integrated systems with exceptional performance. Available in two-way (DSHR) and three-way valves (SE 3), this product line offers high flow rates and rapid step response.
Moog's servocartridge valves feature a poppet and sleeve design (DSHR) in sizes NG 40, 50, 63, and 80 and a spool and bushing design (SE 3) in sizes NG 30, 50, and 63. The SE 3 servocartridge valve has a frequency response of 170 Hz at -3dB and a 12 ms step response time at 100% stroke. The DSHR servocartridge has flow rates up to 6100 l/min [165 gpm](@ 5 bar [72.5 psi] pressure drop) and a 12 ms step response time at 100% stroke. Closed-loop control is through a servopilot valve with a feedback device on the mainstage. On or off-board electronics are available.
Applications such as die casting, high-speed injection molding, and testing equipment benefit from the performance advantage offered by these new servocartridge products.
"Our line of closed-loop cartridge valves will ensure that Moog products, known for quality and technical superiority, are available to meet the highest performance requirements of our customers," commented David Geiger, Manager, Industrial Systems Engineering Manager.
