Description
Shako soft start / dump valve – model VSS
High-quality soft start and dump valve designed for safe and controlled pneumatic system operation, ensuring gradual pressure build-up and reliable system depressurisation.
Valve function & operation
→ Function: Soft start and dump control for pneumatic systems
→ Operation: Energised coil opens valve gradually, throttling air to build pressure slowly; de-energised coil closes inlet and exhausts system pressure
→ Port sizes: 1/4, 3/8 or 1/2 BSP or NPT
→ Exhaust port: 3/8 BSP
→ Pressure range: 0.25 to 9 Bar, test 15 Bar
→ Temperature range: -10°C to +60°C ambient
→ Duty cycle: 100% ED
Construction & materials
→ Body: Aluminium alloy
→ Media: Compressed air
→ Internal mechanism: Throttle-controlled soft start with integrated check valve for dump
Coil & electrical
→ Coil: Low power 4.5 Watt IP65 Class F DIN43650B, 100% duty rated
→ Protection: IP65 with connector (included)
→ ATEX option: EExmIIT4 T4 / T130°C Ex mb IIC T4 and Gb Ex mb tb IIIC T130°C Db for Zone 21 & 22
→ Voltages: 6vDC, 12vDC, 24vDC, 48vDC, 110vDC, 12vAC, 24vAC, 48vAC, 110vAC or 230vAC
Applications & features
→ Gradual system pressurisation for safety and protection of pneumatic systems
→ Controlled exhaust when de-energised, reducing residual pressure to zero
→ Suitable for integration into industrial compressed air networks, machinery start-up sequences, and automated pneumatic systems
