Moog. Inc., Industrial Controls Division, has introduced a new Direct Drive Servo-Proportional Valve that offers the highest flow for applications where greater speed is required. The new D634-P offers this performance advantage, while providing the benefits of safety, energy savings, and responsiveness that characterize Moog’s Direct Drive Valve product line. This valve has integrated electronics and is available in 24 lpm [6 gpm], 40 lpm [10 gpm] and 60 lpm [15 gpm] flow versions at Δp = 5 bar [75 psi] per land. At high pressure drop, this valve holds its maximum flow area nearly constant due to the high spool driving forces, optimized flow force compensated spool design, and the bi-directional working principle of the linear force motor. This results in a higher operational limit and better hydraulic performance compared to conventional valves with proportional solenoids. These features offer design opportunities for equipment manufacturers, which were not possible with previous Direct Drive Proportional Valves. “This new product offers a performance advantage needed by our customers in the wood products, plastics, and metal-forming industries,” said Elizabeth Gerwitz, Marketing Manager, Americas for Moog’s Industrial Controls Division. “This rounds out our Direct Drive Product line, offering a competitive high flow product at an attractive price.” Major benefits of this valve include:
High flow with superior control at higher pressure drops
Low hysteresis and high response sensitivity enabling high performance
Higher performance limits due to flow force compensation on all spool lands
Improved safety due to a spool design that returns to its spring centered position without passing a load move position in case of power failure
Dynamic performance nearly independent of system pressure (low pressure applications)
High spool driving forces resulting in resistance to contamination
Energy savings due to no pilot oil flow and spring centered position
On-board electronics simplifies set-up
