DM 2® Series D Double Valves
DIMENSIONS – inches (mm)
STANDARD SPECIFICATIONS: For DM 2® Series D double valves.
Pilot Solenoids: According to VDE 0580. Enclosure rating
according to DIN 40050, IEC 60529 IP65. Two solenoids, rated
for continuous duty (
additional solenoid on optional reset).
Standard Voltages: 110 volts, 50/60 Hz; 220** volts, 50/60 Hz;
24 volts DC. For other voltages, consult ROSS.
** 220 volts AC not available in the U.S. (OSHA regulations limit
press control voltage to no more than 120 volts AC. Specify voltage
and frequency on order.
Power Consumption (each solenoid):
Size 2, 4, 12, 30:
For primary and reset solenoids:
6.0 watts on DC; 15.8 VA inrush and 10.4 VA holding on AC.
Size 8:
Primary solenoids:
15 watts on DC; 36 VA inrush and 24.6 VA holding on AC.
Reset solenoid:
6.0 watts on DC; 15.8 VA inrush and 10.4 VA holding on AC.
Electrical connection:
Size 2, 4, 8, 12, 30: DIN 43650, Form A. Order connectors separately.
Ambient Temperature: 15° to 120°F (-10° to 50°C).
Media Temperature: 40° to 175°F (4° to 80°C).
Flow Media: Filtered, lubricated or unlubricated (mineral oils
according to DIN 51519, viscosity classes 32-46); 5-micron
recommended.
Inlet Pressure:
Size 2:
45 to 150 psig (3.1 to 10.3 bar).
Size 4, 8, 12, 30: 30 to 120 psig (2.1 to 8.3 bar).
Reset Pressure: For remote air reset option – must be equal to
inlet pressure.
Manual Pressure: Encapsulated, push button actuation.
Pressure Switch (Status Indicator) Rating: Contacts - 5 amps
at 250 volts AC, or 5 amps at 30 volts DC.
Monitoring: Dynamically, cyclically, internally during each actuating
and de-actuating movement. Monitoring function has memory and
requires an overt act to reset unit after lockout.
Mounting orientation: Preferably horizontally (valve on top of base)
or vertically (with pilot solenoids on top).
IMPORTANT NOTE: Please read carefully and thoroughly all of the CAUTIONS on the inside back cover.
