Spool hydraulic directional control valve 30

electrically-operatedpilot-operatedpilot

Product description
The Moog Series 30 is a two‑stage flow‑control servo valve with a dual‑nozzle and mechanical feedback, featuring a stainless steel body and an integrated torque motor in an environmentally sealed compartment. The nozzle‑flapper design delivers high responsiveness, stability and precision in a compact package.
The Series 30 is engineered for reliable long‑life operation in potentially extreme environments; supported operating temperatures range from -40 °F (-40 °C) to 400 °F (204.4 °C).

Features

• Two‑stage flow control with mechanical feedback
• Low‑friction dual‑nozzle pilot stage for high resolution and low hysteresis
• Robust construction for extreme conditions (high shock, vibration or pressure)
• Ultra‑compact, lightweight package
• High response speed for improved controllability
• Stainless steel body and integrated torque motor in an environmentally sealed compartment
