MOOG 631 Equivalent/Replacement, Pilot Operated Servo Valves for Direct-Operated flow control with analog interface, RT6215M
Twin flapper-nozzle electro hydraulic servo valve
- Size: 10
- Maximum pressure: 31.5 MPa
- Rated flow:5-75 L/min ( △ PN=7 MPa)
This Series is proven technology that performs reliably in machines where high performance, stability and accuracy are required. Mechanical Feedback Valves are designed to provide high reliability and long service life. This Series flow control servo valves are throttle valves for 3 and preferably 4-way applications. They are a high performance, 2-stage design that covers the range of rated flows from 5 to 75 l/min (1.3 to 20 gpm) at 35 bar (500 psi) valve drop per spool land.
Features:
- 2-stage flow control Mechanical Feedback (MFB) Servo valve
- Low friction double nozzle pilot stage for high resolution and low hysteresis
- Rugged, long-life design suitable for a wide range of machines
- Small body size
- Integrated fail-safe options enables machine builders to reduce componentry
- Field-configurable 5th port for separate pilot supply offers greater flexibility
- Field-replaceable first stage disc filter for ease of maintenance
Application
find use in various industrial applications, including:
- Motion control with the highest performance.
- Used for turbine for the power station
