Soft-start electric valve for compressed air, APR, SYNTESI® series

The soft start valve is used to fill the working system with compressed air, operating in a two-stage manner. The application of a control signal causes the shut-off valve to open and air to flow through the throttling valve. Once the output pressure reaches approximately 40 to 60% of the supply pressure, the valve is overridden, allowing air to flow through the full cross-section from the inlet to the outlet. Removing the control signal causes the supply valve to close and the working system to vent. The soft start valve is used in installations where there is a need to protect powered actuators from sudden aeration, which can generate shock loads affecting the structural elements of machines. Excessive air intake from the outlet during the initial aeration of the working system can disrupt the operation of the valve, preventing it from fully opening. Size: SY1, SY2. Connection: BSP 1/8" to 1". Supply pressure: 3 - 10 bar. Additional outlet connection: BSP 1/8" for size SY1, BSP 1/4" for size SY2, at the front and rear. Operating temperature: from -10°C to +50°C. Nominal flow: depending on size from 1250 l/min to 4800 l/min (at pressure 6.3 bar Δp = 1 bar).
