HSP1000 Electric Servo On/Off Valve
Spray promptly. Stop smoothly.
Match valve switching to your rolling cycle.
Servo motor and planetary gearbox drive delivers fast switching and precise timing in cooling-water circuits. Set opening and closing speeds independently for fast opening / slow closing, balancing spray timing and water hammer control.
Consider switching speed, pipe stress
and site maintenance together.
Keep spraying aligned with the rolling cycle
Servo motor actuation delivers a full stroke in under 0.4 seconds at maximum speed, supporting rapid spraying in high-speed rolling.
Reduce water hammer and pipe stress
Set opening and closing speeds separately. Fast opening ensures timely spraying; slower closing reduces sudden flow changes and water hammer pressure peaks.
Make operation and maintenance easier
Install the controller in a cabinet away from the valve to reduce exposure to heat and vibration. Motor drive reduces air-circuit maintenance points.
Confirm valve end positions with the PLC
Fully open and fully closed signals are sent to the PLC to confirm actual movement, coordinate subsequent operations and identify switching faults.
Key Performance Data

According to model configuration≤20 ms is servo motor response time. Valve full-stroke time is <0.4 s at the maximum speed setting; slow-closing time depends on the closing-speed setting.
Compared with a pneumatic on/off valve,
which areas can improve?
| Focus Area | Traditional Pneumatic On/Off Valve | HSP1000 Electric Servo On/Off Valve |
|---|---|---|
| Drive & Air Supply | Requires compressed air and related piping | Direct motor drive; no continuous valve air supply |
| Switching & Water Hammer | Movement affected by air supply, piping and solenoid valves | Independent opening and closing speeds; fast opening / slow closing reduces water hammer |
| End-Position Confirmation | Requires limit switches or feedback accessories | Provides fully open / fully closed feedback for PLC coordination |
| Commissioning & Display | Usually relies on manual adjustment and peripheral components | Operating status and fault display; automatic homing calibration |
| Maintenance | Inspect cylinders, solenoid valves, air piping and connections | Fewer leakage and blockage troubleshooting points |
Servo on/off valve questions
Is servo response time the same as valve full-stroke time?
No. The ≤20 ms figure refers to servo motor response time. The HSP1000 valve completes a full stroke in under 0.4 s at the maximum speed setting. The actual closing time depends on the selected closing speed.
Why use fast opening and slower closing for cooling water?
Fast opening helps start spraying promptly. Slower closing reduces sudden flow changes and water-hammer pressure peaks. Opening and closing speeds can be set independently to suit the cooling circuit.
How is valve switching coordinated with workpiece arrival?
A hot metal detector identifies workpiece presence and position. The control system uses that signal to issue a switching command, while fully open and fully closed feedback helps the PLC confirm valve movement.
What information is needed for a cooling-water valve retrofit?
