Cartridge Valves - Flow Control Valves - Flow divider and combiner

DRFN-12A

RE18321-33-01(2023-11-07)
Description

Input flow at 3 will be divided and output equally to 2 and 4 independent of system pressures. Flow input at 2 and 4 will be combined and output at 3. Should either 2 or 4 become blocked in flow division mode, approximately 5% of the input flow will be transmitted to the open port.

¹) Only external seals for 10 valves

Slippage (tolerance) from theoretical divided flows: ±5% to ±10%, depending from inlet flow (see diagram). N.B. Slippage is lowest toward upper limit of nominal range.
