Valve assembly for evaporative coolers

This float valve assembly controls water level in evaporative cooling systems using a 1/4 inch compression connection. The bronze body and brass rod provide corrosion resistance for continuous water service. A polyethylene float operates the valve mechanically without external power. The unit mounts through an 11 inch bulkhead for tank or reservoir installation.

Flow response at varying supply pressure

At 50 psi supply pressure the valve passes 1.5 gallons per minute, rising to 3 gallons per minute at 100 psi. The maximum rated pressure is 100 psi and the maximum water temperature is 140 degrees Fahrenheit. The valve modulates flow as the float rises and falls, maintaining level without pressure spikes. Sustained operation stays within these pressure and temperature limits.

Bronze body with compression and bulkhead mounting

The bronze valve body and brass rod withstand long-term exposure to mineral-rich water. A 1/4 inch compression fitting connects supply tubing without soldering. The 11 inch bulkhead mounting spans the tank wall and secures with a 3/4 inch thread. The transparent polyethylene float allows visual confirmation of position during routine checks.

Questions about this item

How much heat does the Watts C1/4TFAE float valve assembly generate when it runs continuously?

The valve body is bronze and the float is polyethylene, so the assembly itself produces no measurable heat during normal operation.

What existing plumbing connections are required to install this 1/4 in compression float valve?

You need a 1/4 in compression fitting on the supply line and an 11 in by 3/4 in bulkhead opening for the mounting flange.

Will the 1/4 in -20 brass rod thread match the float arm on my older evaporative cooler?

The rod uses a standard 1/4 in -20 thread, which is common on many legacy cooler float arms, but verify your existing arm thread pitch before installing.
