PVC Bag Filter 01 - Hayward Flow Control
The FLV Series Bag Filter Vessels are available in durable PVC and CPVC construction, engineered with a true-union design. End connection options include socket, threaded, or flanged styles, with metric (DIN/EN) connections also offered. These vessels are especially well-suited for demanding applications such as sodium hypochlorite and bleach processing, thanks to their excellent chemical resistance.
Each unit comes standard with FPM seals, with EPDM available as an option. The vessels are pressure rated to 150 psi at 70°F non-shock. Offered in both Size 1 and Size 2 configurations, the FLV Series is available as single (Simplex), dual (Duplex), or triple (Triplex) assemblies, providing flexible solutions for a wide range of liquid filtration requirements.

The maximum recommended fluid velocity through this product is eight feet per second (8 ft/s). Higher fluid velocity can create excess water hammer effect, resulting in property damage, personal injury, or even death. Please refer to I.O.M.
| Connection | Velocity | Approx Flow Rate lt/hr | |
| DN32 | 1-1/4" | 8 feet/sec | 6,900 |
| DN40 | 1-1/2" | 8 feet/sec | 10,110 |
| DN50 | 2" | 8 feet/sec | 16,830 |
Velocity in Schedule 80 Plastic Pipe for Water - Safe Flow Velocity
Hayward establishes a generally accepted safe flow velocity for plastic piping systems. For systems without fast opening or closing valves, a maximum velocity of 8 feet per second is recommended. However, for systems equipped with such valves (like solenoid or pneumatically actuated valves lacking speed controls), the maximum velocity is typically limited to 5 feet per second. In contrast, metal piping systems are often designed to accommodate flow rates of up to 15 feet per second, significantly higher than those acceptable for plastic systems. This distinction is crucial when considering the installation of plastic components such as valves, strainers, or filters within a metal system.
