Engineered for precision motion control systems requiring gradual pressure buildup, the GV40010NB features an adjustable soft-start function to prevent mechanical shock. Its corrosion-resistant aluminum alloy body with nickel plating withstands harsh environments. Requires 25μm filtration with oil mist (ISO 8573-1 class 4). Includes manual override and position indicator.
- Robotic arm end-effector force control
- Injection molding machine clamp sequencing
- Elevator door safety brake systems
- Semiconductor wafer handling equipment
- Hydraulic-to-pneumatic transition units
Installation guidelines:
Mount horizontally with coil upright. Allow 15mm clearance below for exhaust.
Use anti-vibration washers in high-frequency applications. Lubricate with ISO VG32
turbine oil if operated below -5℃.
Critical note:
Do NOT use silicone-based lubricants. Minimum 200ms delay required between
consecutive actuations for heat dissipation.
