If the directional valve on a PMC PH-25 does not work, follow these troubleshooting steps:
1. Check if the directional indicator light is ON: - If ON, check the reversing valve coil on the side with the light. - Measure voltage at the plug; it should be 24 volts DC. - Check coil resistance; it should read approximately 19 ohms. - If resistance is incorrect, replace the coil or reversing valve.
2. If the directional light is OFF: - Move the reversing switch plate away from the switch. - Bleed down the chemical pressures. - Ensure the pump switch is OFF. - Turn ON the motor. - Locate the actuation coils at the directional valve. - Manually shift the spool by pressing the small round tab in the center of the appropriate coil: - If the reversing plate is all the way left, press the right coil. - If it's all the way right, press the left coil.
Warning: Ensure the motor is OFF and the pump switch is OFF before manual operation.

Always use liquids and solvents that are compatible with the unit. If in doubt, consult your PMC Distributor. When working with the PH Series Proportioner, it is recommended that the operator wear suitable clothing and elements of personal protection, including, without limitation, gloves, protective goggles, safety footwear, and face masks.
CHARACTERISTICS Classic PH Series Proportioner has been designed and built for the application of polyurea chemical systems, polyurethane foam chemical systems, and some specific two- component epoxy systems. PRINCIPAL HEATING SYSTEM The Proportioners consist of two (2) independent Material Heaters without internal seals. Each heater for the PH(X)-25 Proportioner has four (4) Heating Elements rated at 1,000, 1,250 or 1,500 watts, each giving the Proportioner a total heat of 8,000, 10,000, or 12,000 watts.
CHARACTERISTICS PRESSURE BALANCE CONTROL SYSTEM The Pressure Balance Control (PBC) system provides better control over a chemical pressure imbalance. When the system is turned off, the Proportioner will perform as if there is no PBC system and will continue pumping material. When the system is turned on, it will continually monitor the pressure between the two chemicals (known as the pressure differential).
