description

Everfilt® 4-Inch E-Resist® Valves are a 3-port, two-way valve, combining both filtration and backwash modes in a single unit. Designed to be fully open in either position, giving full unrestricted flow at all times. Constructed for specific applications where corrosive liquid and or elements are present. Constructed from E-Resist® iron and finished with epoxy interior finish and two-part epoxy exterior. The service port and flush port are used instead of standard maintenance, where severe conditions require interim maintenance. Service Port: Remove the rubber cover and inspect interior of the actuator housing and backwash shaft. Lubricate backwash with light weight oil or an aerosol spray (WD-40). Hydraulically operate the actuator to ensure proper operation. Replace rubber cover to protect actuator interior. Flush Port: To flush the diaphragm, remove 1/4" drain plug and manually operate the actuator control valve to initiate a backwash. Source water will enter the actuator and flush the accumulated debris out of the flush port. Repeat this cycle as required. Replace 1/4" drain plug and return the actuator control valve to normal mode for proper operation.
