Key Features:
-
Floating ball + soft seal → leakage below industry standard
-
Cast bronze body resists corrosion and tolerates high temperature
-
Millisecond coil response for rapid on/off control
-
Low coil power consumption (energy-saving)
-
Dual-coil design for redundant/safe switching in press and brake applications
-
Explosion-proof and over-pressure protected
Application Scenarios:
-
Steel rolling, forging, glass bottle making, primary aluminium production
-
Machine braking systems, pneumatic actuator control, pressure regulation
-
Heavy-duty industrial pneumatic circuits
Installation & Usage Notes:
-
Use only with dry gas medium; moisture will degrade seals.
-
Confirm voltage polarity and level (DC 24 V / AC 110 V) before energizing.
-
Verify port threading (NPT vs. BSPP) matches the pipeline.
-
Ensure the working pressure stays within 2–10 Bar.
-
For safety-critical applications (press brakes), follow ROSS dual-valve safety guidelines.
-
Do not exceed 175 °C ambient/media temperature.
