Overview of DM 1 Series E Double Valve Function Valve de-actuated (ready-to-run): The flow of inlet air pressure into the crossover passages from the inlet chamber is restricted by orifices that allow air pressure to bypass the lower inlet poppets. Flow is sufficient to quickly pressurize the pilot supply/timing chambers on both sides A and B. The upper inlet poppets prevent air flow from the crossover passages into the outlet chamber.
STANDARD SPECIFICATIONS Pilot Solenoid Power Consumption (each solenoid): 6.0 watts on DC; 15.8 VA inrush and 10.4 VA holding on AC. Solenoids: According to VDE 0580. Enclosure rating according to DIN 400 50 IP 65. Connector socket according to DIN 43650 Form A. Three solenoids, rated for continuous duty. Standard Voltages: 110 volts AC, 50/60 Hz; 24 volts DC. Temperature Range: Ambient: 15° to 122°F (4° to 50°C). Media: 40° to 175°F (4° to 80°C).
ACCESSORIES ELECTRICAL CONNECTORS STATUS INDICATOR Wired connectors have a 2-meter (61/2 ft) cord with three 18-gauge conductors. Cord is available in either 6-mm or 10-mm diameter and with or without indicator light. The Status Indicator pressure switch actuates when the valve is in a ready-to-run condition and de-actuates when the valve is in a lockout condition or when the inlet air pressure has been removed.

Overview of DM2® Series C Double Valve Function The flow of inlet air pressure into the crossover passages is restricted by the size of the passage between the stem and the valve body opening. Flow is sufficient to quickly pressurize pilot supply/timing chambers A and B. The inlet poppets prevent air flow from crossover passages into the outlet chamber. Air pressure acting on the inlet poppets and return pistons securely hold the valve elements in the closed position.
STANDARD SPECIFICATIONS Pilot solenoid: According to VDE 0580. Rated for continuous duty. Standard voltages: 24 volts DC, 110 volts AC (50/60 Hz), 220** VAC (50/60 Hz). 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. Power consumption (each solenoid): Size 4, 12, 30: Primary and reset solenoids: 5.8 watts on DC; 15.8 VA inrush and 12.8 VA holding on AC.
