Precision slow-start pneumatic valve engineered for controlled actuator acceleration. Features anti-water-hammer design with progressive pressure buildup (0.1-3 sec adjustable). Nickel-plated brass body with stainless steel core components ensures corrosion resistance in humid environments. Includes LED status indicator and surge protection circuitry.
- Precision assembly robots requiring smooth motion profiles
- Elevator door control systems for gradual opening/closing
- Injection molding machine ejector sequencing
- Food processing pneumatic actuators needing splash resistance
- Semiconductor handling equipment with vibration-sensitive operations
Installation protocol:
Install downstream of 5μm filter regulator. For optimal performance,
maintain 0.3m/sec maximum air velocity in connected piping.
Lubrication not required (maintenance-free design). Replace desiccant
every 2,000 operating hours in high-humidity environments.
