How Everfilt®
Backwash Valves Work?
Everfilt's Backwash Valves work by using hydraulic pressure from the filter’s own water supply to automatically shift the valve between filtration and backwash modes, allowing trapped debris to be flushed out of the filter media and discharged through the backwash manifold before returning the system to normal filtration. These backwash valves are manufactured by Everfilt®.

FAQ Frequently Asked Questions
FOR EVERFILT® BACKWASH VALVES
1. What is the Difference Between the 3" & 4" Models?
The primary differences are flow capacity and valve size:
-
Flow Coefficient (Cv): 115 (3") | 175 (4")
-
Standard Pressure Rating: 125 PSI (3") | 125 PSI (4")
-
Modified / HP Pressure Rating: 250 PSI (3") | 250 PSI (4")
-
Total Length: 13.25" (3") | 15.5" (4")
-
Typical Application: Medium Flow (3") | High Flow (4")
The 4" valve is typically selected for larger filtration systems with higher flow requirements.
2. How Does the Backwash Valve Operate?
During filtration mode, the backwash valve allows water to flow normally through the filter. When a backwash cycle is initiated, hydraulic or pneumatic actuation shifts the valve internally to close the inlet port and open the backwash port, reversing water flow through the filter media to flush contaminants out of the system.
3. What Are the Backwash Valves Made From?
Everfilt® backwash valves are constructed from ductile iron with:
-
3M-134 NSF-approved interior epoxy coating
-
Fuze-coated exterior protection
-
304 stainless steel internal components
This construction helps provide long-term corrosion resistance and durability in harsh environments.
4. Are the Backwash Valves Designed for Automatic Systems?
Yes, Everfilt® backwash valves are designed for:
-
Automatic backwash systems
-
Hydraulic actuation
-
Pneumatic actuation
-
Manual operation
They are commonly paired with Everfilt® backwash control panels for fully automated filter cleaning.
5. Can the Backwash Valves be Serviced or Rebuilt?
Yes, Everfilt® offers rebuild kits and replacement components including:
-
Diaphragms
-
Springs
-
Packing glands
-
Cover plates
-
Complete rebuild kits
This allows users to extend service life without replacing the entire valve assembly.
6. Are Everfilt® Backwash Valves Compatible with Older Filtration Systems?
In many cases, yes. Everfilt® backwash valves can often be integrated into existing filtration systems or retrofitted into older installations depending on piping layout, pressure requirements, and control compatibility.
