V-Series Valves
The V-Series ranges in size from 3/8” to 2” and operates efficiently with liquids of any viscosity at pressures from 3 to 1000 psi. Fulflo’s V-Series valves are available with threaded and flanged connection, with standard or handwheel design, in a choice of Brass, Cast Iron, Steel, and Stainless Steel.
FV-Series Valves
The FV-Series offers the same valve sizes, flow range and materials as the V-Series, but with a design that prevents liquid and gas venting during normal operation and adjustment conditions. This safety feature prevents the adjusting screw from backing out while adjusting the pressure setting. The design of FV-Series valves accommodates threaded and flanged connection.
OV-Series Valves
The OV-Series is specially designed for applications where variable back pressure is a problem. OV-Series valves range in size from 1/2″ to 2” and operate efficiently with liquids of any viscosity at pressures from 10 to 500 psi. OV-Series valves are available with threaded and flanged connection in a choice of Brass, Cast Iron, Steel, and Stainless Steel.
A-Series Valves
The A-Series offers both Direct Acting and Internal Pilot operated models in a choice of threaded or flanged connection. Threaded models are available in 2.5″ and 3″ sizes, while flanged models come in 2.5″, 3″ and 4″.
Direct Acting models operate efficiently with liquids of any viscosity at pressures up to 150 psi; the Internal Pilot handles pressures up to 500 psi. A-Series valves are available in a choice of Cast Iron, Cast Steel, and Stainless Steel.
SVB-Series Valves
The SVB-Series is specially designed for flammable fluids and is ANSI and UL-842 Approved. SVB-Series valves are suited to use with fuel oils on oil burner services, and in any application requiring Underwriter Listed valves.
The SVB-Series ranges in size from 3/8″ to 2” and operates efficiently with liquids of any viscosity at pressures from 3 to 500 psi. SVB-Series valves feature threaded connection and Brass construction.
