4" INCH HIGH-PRESSURE BACKWASH VALVES
description
Everfilt® 4-Inch High-Pressure Backwash 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 that require high-pressures. Constructed from ductile iron and finished with a fuze coated exterior and 3M-134 NSF-Approved interior epoxy and fuze coat exterior. The service port and flush port are used instead of standard maintenance, where severe conditions require interim maintenance. Service Port: Remove 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 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 actuator control valve to normal mode for proper operation.
