SUN Overflow Valve RBAP-MDN Cavity Pilot Control Cartridge With Manual Override

This 2-port, pilot-stage, direct-acting relief cartridge is an electro-proportionally controlled pressure regulating valve featuring infinite, stepless adjustability within the selected pressure range.

• Proportional control enables precise pressure adjustment
• Utilizes Sun T-8A cavity for compatibility with main stage pressure control elements
• Eliminates need for separate pilot lines - single cavity accommodates both control and primary functions
• Manual override (L control) allows adjustment during electrical failure and pressure range offset
• Damped construction ensures stable operation across wide operating conditions
• EPDM seals available for phosphate ester fluid systems

• Model Weight (with coil): 1.00 lb
• Valve Installation Torque: 20-25 lbf ft
• Valve Hex Size: 7/8 in.
• Solenoid Tube Diameter: 0.75 in.
• Reseat: >85% of setting

For proper installation, first install the main stage valve to correct torque value, followed by the T-8A pilot control section into the main stage valve to its required torque value. For optimum performance, use an amplifier with current sensing and adjustable dither (100-250 Hz recommended).
