Paddle Flow Switches
DS1402
AIR / LIQUID MINI FLOW SWITCHES
The Model V10 paddle flow is perfect for flow control in smaller
pipe sizes at higher system pressures. Unique patented switch
adjustment enables quick changes between Normally Open (NO)
and Normally Closed (NC) - just loosen two screws and slide the
reed switch to your choice of switch actions. Tighten screws and
it’s complete in seconds! Solid metal bodies enable operation at
high system pressures of 69 barg for brass units or 138 barg for
stainless steel. The vane is specially formed for maximum
strength and has a removable laminated trim template showing
where to cut for water or air flows in six pipe sizes from 1/2” to
2”. An index arrow on side of the body indicates correct flow
direction.
