N56D Manual Multiport Filter Valve
The N56D manual multiport filter valve provides a flow rate of 10m³/h and adopts a corrosion-resistant gasket for opening and closing. It can be applied as a service, backwash, or fast rinse valve. It can also work under pressure. With a rotating handwheel, you can easily switch the settings without turning off the pump. The filter can be used in residential filtration systems, swimming pool filtrating, and RO pretreatment filtration systems.

Note: The listed activated carbon filter flow rate is the outcome of calculation based on a flow velocity of 12m/h; The backwash rate is based on a backwash intensity of 10L/(㎡*s). The above sand filter flow rate corresponds to a flow velocity of 25m/h; The backwash rate is related to a backwash intensity of 15L/(㎡*s)

Product Characteristics
- It adopts hermetic head faces with a high degree of pottery and corrosion resistance for opening and closing.
- No water passes the valve in rinse in single tank type.
- Reasonable design of the flow passage: Service→ Fast Rinse→ Backwash → Fast Rinse → Backwash →Service.
- It can be changed to a side-mounted valve with a side-mounted connector.
- It can operate under pressure, without leakage.
Range of Application
- Residential filtration system
- Swimming pool filtration equipment
- Active carbon or sand filter in RO pretreatment filtration system
