2/2 PILOT OPERATED DIAPHRAGM SOLENOID VALVES

2/2 PILOT OPERATED DIAPHRAGM SOLENOID VALVES

PRESSURE DIFFERENCE REQUIRED FOR VALVE OPERATION

TEHNICAL 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
• Duty cycle: continuous (ED100%)
• Cycling rate: 10 - 100 cycles/min
• Electrical protection: IP65 (with plug to ISO 6952 / ISO 4400)
Long term use in humid environment requires the use of sealing sets.
