Advantages
Ultra-high flow density
Achieves a rated flow rate of 1000 L/min with a smaller installation area, reducing pipe diameter and valve block volume, and lowering system costs.
Extremely high dynamic response100% stroke step response of 4~12 ms, frequency response >110 Hz (±5%), meeting millisecond-level control requirements for high-acceleration impact tests, rolling mill AGC, etc.
Three-stage ServoJet® pilot structureThe jet tube pilot stage has better contamination resistance than nozzle baffles, reducing oil cleanliness requirements to ISO 19/16/13, ensuring high field reliability.
Integrated electronic controlBuilt-in SMD amplifier and LVDT valve spool position closed-loop control, supporting ±10 mA/±10 V commands, allowing direct connection to PLCs/motion controllers without external servo boards, simplifying wiring.
High environmental adaptabilityVibration resistance 30 g (10 Hz~2 kHz), shock resistance 50 g; operating temperature −20 °C~+80 °C, suitable for high-vibration and high-temperature environments such as rolling mills, ships, and steam turbines.
Field adjustable & diagnosticsProvides zero point, gain, and chatter potentiometers and LED status indicators; supports fieldbus options, allowing remote reading of valve core position, temperature, and fault information, reducing commissioning and downtime.
Applications
Steel rollingAutomatic thickness control (ACG) for cold/hot rolling mills, and automatic control for roll bending and flatness (AFC), achieving thickness accuracy within 5 μm using high flow rate and fast response.
Dynamic testing and material experimentationMulti-channel road simulators, fatigue testing machines, and earthquake simulation benches, requiring force or displacement reversal within a 10~20 ms period; the D792 series combines frequency response and flow rate.
Metal Forming and PressesHigh-speed stamping, hydraulic stretching, and powder metallurgy presses; the high acceleration capability of the valves shortens the pressing cycle and improves the dimensional consistency of finished products.
Steam and Gas TurbinesAs a main steam valve/fuel servo valve, a 350 bar rated pressure and anti-fouling structure ensure long-term continuous operation.
Marine and Marine EngineeringSteering gear, deck winches, and semi-submersible platform lifting control; shock-resistant and fire-retardant liquid (water-glycol) compatible versions meet classification society requirements.
Injection Molding/Die Casting MachinesWhen high-flow, high-speed injection is required, the D792-4034 can replace multiple parallel proportional valves, reducing pressure loss and achieving energy savings and noise reduction.
