2/2 PILOT OPERATED DIAPHRAGM SOLENOID VALVES

2/2 PILOT OPERATED DIAPHRAGM SOLENOID VALVES 1/2" - 2"

PRESSURE DIFFERENCE REQUIRED FOR VALVE OPERATION
TECHNICAL DATA

  • Internal parts: stainless steel
  • Seals: NBR, EPDM, FPM
  • Fluid temperature: -10°C to +85°C (NBR); +100°C (EPDM, FPM)
  • Ambient temperature: +55°C max
  • Viscosity: 21 mm2/s max.
  • Response time: opening 0.05 - 1 s; closing 0.5 - 4 s
  • Voltage: 230, 115, 48, 24 V AC; 24, 12 V DC
