Moog Inc. has introduced the new D927 proportional valve to complete its direct operated servo-proportional valve line. The D927 is an ISO 4401 size 05 valve, built to complement the D926 size 03 valve introduced in April 2022. Like the D926 valve, the D927 is a direct-operated valve with integrated electronics driven by two proportional solenoids. Equipped with integrated microcontroller-based electronics, it offers closed-loop spool position control. The D927 valve is capable of flow rates up to 75 lpm at 10 bar (19.8 gpm at 150 psi). Together with the D926, this series is now capable of flow ranges of 4 to 75 lpm. The D927 perfectly completes the portfolio of directly operated proportional valves.
The D927 proportional valve is suited for highly dynamic tasks such as the control of position, speed, pressure, and force in open and closed loop industrial applications. Customers will benefit from a robust design that is particularly resistant to vibration and temperature. It is this robustness that sets this valve apart from its competitors. Furthermore, this valve includes several standard features, such as 4/3-way design with a spring-centered failsafe position.
“With its higher flow rate, the D927 proportional valve series complements our D926 series valves,” said Dr. Marco Wiegandt, Valve Development Manager for Moog. “We’ve designed the D927 to be rugged, withstand fluid temperatures up to 80° C, and perform reliably under extreme vibration. These capabilities make the D926 and the D927 valves more than just a cost-effective replacement for competing products in this segment.”
The new D927 valve is ideal for applications with increased demands on control accuracy and precision, such as in plastics machinery, presses and the wood industry. With its rugged design, this valve will also perform well in harsh ambient environments, such as heavy industry, metal forming and presses, or gas and steam turbines. The D27 is also suited for highly dynamic applications such as test laboratories or test rigs.
