Bobby R1350 3/4 Float Valve SS Viton Seal

SKU CH-01QH-9S4CJ

A 3/4-inch stainless-steel float valve with Viton seal rated to 85 psi and 450 °F, delivering 38 gpm at 35 psi and 58 gpm at 85 psi

  • 3/4 inch FNPT connection fits standard horizontal piping
  • Stainless steel body with Viton seal resists corrosion
  • NSF compliance meets water-quality standards
  • 38 gpm flow at 35 psi supplies strong output
  • 58 gpm flow at 85 psi handles high demand

Bobby R1350 Float Valve

The Bobby R1350 is a 3/4 inch float valve built for horizontal piping installations. Its stainless-steel body and Viton seal suit commercial and industrial water systems that require NSF compliance and resistance to aggressive fluids. The FNPT connection and 1/4-20 rod thread simplify integration into existing tank or reservoir assemblies.

Thermals noise and power draw

The valve operates mechanically without electrical power so it generates no noise or heat of its own. Stainless-steel construction withstands continuous water temperatures up to 450 degrees Fahrenheit while maintaining seal integrity. Maximum working pressure is rated at 85 psi for safe operation in standard supply lines.

Sustained load behaviour

Flow capacity increases with pressure: 38 gallons per minute at 35 psi and 58 gallons per minute at 85 psi. The Viton seal and all-stainless internals resist wear during prolonged high-temperature or high-pressure cycles. California Proposition 65 warnings apply because the product contains listed chemicals.

Questions about this item

How do I install the Bobby R1350 float valve with its 3/4 inch FNPT connection and 1/4-20 rod thread?

Thread the 3/4 inch FNPT inlet onto horizontal piping using pipe sealant on male threads only; then secure the operating rod into the 1/4-20 thread without cross-threading, which is the step most often done wrong.

What maintenance will the stainless steel body and Viton seal need over time?

Inspect the Viton seal annually for hardening or chemical attack from water treatment; replace the seal if leakage appears at the seat, while the stainless steel body typically requires no service.

At what pressure limit does the valve reach its maximum rated flow of 58 gpm?

The valve delivers 58 gpm at its maximum rated pressure of 85 psi; sustained operation above 85 psi exceeds the design limit and will cause seat erosion or seal failure first.
