Precision slow-start valve featuring adjustable acceleration control through its unique throttling mechanism. The GV20008NF minimizes mechanical shock in pneumatic systems with its progressive pressure buildup design, achieved through an integrated needle valve and check valve combination. Its aluminum alloy body with hard anodizing resists chemical corrosion in harsh environments.
- Robotic arm gripper pressure sequencing
- Elevator door safety mechanisms
- Plastic injection molding clamp control
- Food packaging machine actuator soft-start
- Lithium battery production line tooling
Installation protocol:
Mount horizontally with arrow aligned to airflow direction.
Use copper-free lubricant on threads. Requires 15mm clearance
behind manifold for maintenance access. Perform initial
adjustment via hex key (2mm) on flow control screw.
Critical note:
Not compatible with phosphate ester fluids.
Always install downstream filter (5μm minimum).
Maximum permissible ambient vibration: 4.9m/s²
