* Parts included in Repair Kit requiring replacement.
(a) A quantity of one (1) of the seals is required depending on the solenoid valve style being repaired. The spring return side of the ceram valve dœs not have piston seals, therefore only the piston seal on the solenoid side of the valve requires replacement. Replace the worn seal with a new one of the same type. (b) A quantity of one (1) of the subplate gaskets is required depending on the solenoid valve style being repaired. Replace the worn subplate gasket with a new one of the same type. (c) The QRV diaphragm or the QRV plug is used when rebuilding the QRV on the solenoid side of the ceram valve depending on the style. If the ceram valve dœs not have a removable QRV seat, install the green diaphragm in place of the gray one. If there is a removable QRV seat, discard seat and "O" ring and install the QRV plug and new "O" ring. The spring return side dœs not require a diaphragm or plug.
