How Does a Swing Check Valve with Lever & Weight Work?
Forward flow moves the hinged disc away from the seat, allowing water to pass through the valve. As flow slows or begins to reverse, the disc swings back toward the seat to help prevent reverse flow.
The external lever-and-weight assembly assists the disc-closing action and provides an external indication of disc movement. Proper lever and weight adjustment, installation orientation, and system operating conditions should be confirmed using the manufacturer's technical information.
Lever & Weight vs. Standard Swing Check Valve
Lever & Weight – Figure 22FCW
- External lever-and-weight assembly
- Assists disc closing action
- Provides visible indication of disc position and movement
- Useful where additional control of closing characteristics is desired
- Optional spring kits available for specialized applications
Standard Swing Check – Figure 22FC
- Traditional internal swing-disc operation
- No external lever-and-weight assembly
- Automatic response to forward and reverse flow
- Simpler external valve configuration
- Common for general water-distribution service

Fusion-Bonded Epoxy Coating
The Figure 22FCW features a fusion-bonded epoxy coating conforming to ANSI/AWWA C550. The coating protects internal and external ductile iron surfaces and provides corrosion resistance for compatible water-service applications.
Review project requirements and manufacturer documentation when specific coating thickness, surface preparation, certification, or environmental requirements must be confirmed.
Resilient Disc & Brass Seat
Resilient Disc
The resilient disc forms the primary closing element and is designed to return toward the seat as forward flow decreases or reverse flow begins.
Brass Seat
The brass seat provides the mating sealing surface for the resilient disc and supports dependable check-valve closure.
Optional Spring Kits
Spring kits are available for specialized applications where additional assistance or control of the disc-closing action may be required.
Spring selection and use should follow the manufacturer's recommendations. Confirm application, installation orientation, flow conditions, and system requirements before specifying an optional spring kit.
Common Applications
Water & Utility Systems
- Municipal water-distribution systems
- Water-service piping
- Pump discharge piping
- Utility piping systems
- Water-treatment facilities
Commercial & Industrial Systems
- Commercial water systems
- Industrial water piping
- Mechanical-room installations
- Building-service water systems
- Compatible flanged piping systems
Flanged Connection
The Figure 22FCW uses flanged connections for integration into compatible AWWA and mechanical piping systems. Flanged connections provide a bolted, serviceable joint and are commonly used on larger water-distribution piping.
Verify mating flange dimensions, gasket selection, bolting requirements, pressure rating, alignment, and project specifications before installation.
Installation Guidance
- Confirm the required valve size before ordering.
- Verify that the 300 PSI CWP rating is suitable for the intended system.
- Confirm compatibility with the system fluid and operating conditions.
- Verify mating flange compatibility before installation.
- Confirm required valve orientation and flow direction.
- Inspect the valve, disc, seat, coating, lever, weight, and flange surfaces before installation.
- Remove shipping materials and foreign debris from the valve and piping.
- Properly align mating piping and flanges before tightening bolts.
- Do not use flange bolts to force misaligned piping into position.
- Use suitable gaskets and bolting for the piping system and project requirements.
- Tighten flange bolting using an appropriate cross-pattern procedure.
- Confirm the lever-and-weight assembly is installed and adjusted according to manufacturer instructions.
- Use optional spring kits only where appropriate for the application.
- Provide adequate piping support so external piping loads are not transferred improperly to the valve.
- Inspect and test the completed installation before placing the system into service.
- Installation should be completed by qualified personnel familiar with AWWA check valves and flanged piping systems.
