7 Float Valves, Float Switch, Procon Pumps & Motors, Bulkhead Fittings
Reverse Osmosis
Mechanical Float Valve
FV03
These float valves are completely mechanical and require no electrical power or wiring. Mechanical
linkage of float and valve assures positive on-off action. When liquid levels drop, the float drops and
activates the tank fill. When levels rise, the float rises and turns off the fill. These valves are fitted with
an adjustable arm and are bulkhead mountable both horizontally and vertically. Inlet size is 3/8" tubing
with a free flow outlet, a .093 orifice and stainless steel hardware. Estimated flow rate is 1.5 GPM at
40 PSI and have been tested to 100 PSI+. Valve comes complete with jam nut, sealing washer and
float attached.

Mechanical Level Switches
FLOAT SWITCH-NC-110
Used to control pumps, motors or other electrical devices. Normally Open (N.O.) or Normally Closed
(N.C.) refers to the switch contacts when the bulb is hanging in a vertical position. Use N.O. to turn a
device on with high level, N.C. to turn it off with high level.

Normally Open 10' Cord
FLOAT SWITCH-NC-110
Normally Closed 15' Cord, 110 Volt
FLOAT SWITCH-NC-220
Normally Closed 15' Cord, 220 Volt
Level Float Switch
LFS4400-05
Features a strong Alnico bar magnet hermetically-sealed inside so no other wetted material can
contaminate liquid or be attacked by a corrosive liquid. Special molded thread helps when metal to
plastic installations are used. Unique assembly procedure eliminates stress by actually suspending
the reed switch allowing for thermal expansion and contraction. Round pivot pins add bearing surface
for smooth operation and due to design clearances, squeeze out the liquid from either side during
operation to help eliminate build-up. Lead Wires – 24" long. Operating Pressure – 150 PSIG Max.
Operating Temperature – -40° F. to 225° F.

Procon Pumps & Motors
Procon pumps are rotary vane, positive displacement pumps and are
ideal for many clean fluid applications requiring flow rates up to 660
gph and discharge pressures up to 250 psi. Each pump is quiet in operation and requires no lubrication
or maintenance during its life span. Most models are self-priming and are available in brass or 303
stainless steel construction.
