  • NSF compliance confirms suitability for potable water use

Application and user

The Bobby R1371-1 float valve is a stainless steel component with a PTFE seal designed for horizontal piping installations. It suits plumbing professionals and facility managers who need a reliable 1-inch FNPT connection for water supply control. The valve body and internal material are stainless steel, providing corrosion resistance in demanding environments. It carries NSF compliance for potable water systems.

Sustained-load behaviour

At a supply pressure of 35 psi the valve delivers a flow rate of 53 gpm, while at 85 psi the flow increases to 71 gpm. The maximum rated pressure is 85 psi and the maximum operating temperature reaches 550 degrees F. The PTFE seal maintains integrity across this pressure and temperature range during continuous operation. These figures define the steady-state performance envelope.

Interface limits

The valve uses a 1-inch FNPT connection and a 3/8-16 rod thread for mechanical linkage. No float or rod is included, so the buyer must supply compatible hardware. The 85 psi pressure ceiling and 550 degrees F temperature ceiling are hard limits that must not be exceeded. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How much heat can the 1 in stainless steel float valve with PTFE seal handle during continuous operation?

The valve is rated for a maximum temperature of 550 degrees Fahrenheit, so it will withstand typical hot-water system temperatures all day without degrading.

What piping connection must already be in place for the 1 in FNPT float valve to install directly?

You need a horizontal pipe with a 1 inch female NPT thread; the valve threads onto that connection without extra adapters.

Will the 85 psi maximum pressure rating work with older supply lines that run at lower pressure?

Yes, the valve operates at pressures up to 85 psi and delivers 53 gpm at 35 psi or 71 gpm at 85 psi, so it functions well on older, lower-pressure lines.
