Overview
Fulflo was established in 1912. Located in Blanchester, OH, Fulflo was incorporated in 1933 under it’s present name and trademark. Patents for the original guided piston, direct acting relief valve were obtained in 1935, coincident with the onset of fluid power systems. The need for providing large flows without excessive bulk was subsequently met by the pilot-valve-control relief valve which was patented in 1943.
Fulflo parts and valves are used in oil and gas refineries, are essential to the military including ships and aircraft carriers, and even provide fun for attendees on amusement roller coaster rides.
V-Series Hydraulic Bypass Relief Valves
Standard with Screw Connections, Standard with Flange Connections, Stainless Steel with Screw Connections, Handwheel with Screw Connections, and Handwheel with Flange Connections in a choice of brass, cast iron, steel, and stainless steel.
The Fulflo V-Series valves range in size from 3/8″ – 2″ and operate with liquids of any viscosity at pressures from 2 – 1000 p.s.i. The valves are adjustable, mount in any position, and allow for flow rates up to 150 GPM.

FV-Series Hydraulic Bypass Relief Valves
Fulflo FV2000 Series Hydraulic Bypass Relief Valves are similar to the V-Series valve and includes a new safer design that protects liquid and gasses from venting out of the valve during normal operation and adjustment conditions. This valve has been especially designed to prevent the adjusting screw from backing out while making adjustments to the pressure setting. An o-ring has been incorporated around the adjusting screw to further prevent liquid from escaping.
The Fulflo FV-Series valves range in size from 3/8″ – 2″ and operate efficiently with liquids of any viscosity at pressures from 2 – 1000 p.s.i. The FV-Series valves are available in flange or screw type in a choice of brass, cast iron, steel, and stainless steel. They can be mounted in any position.

OV-Series Hydraulic Bypass Relief Valves
Fulflo OV-Series Hydraulic Bypass Relief Valves come in 3 types:
Standard with Screw Connections, Standard with Flange Connections, and Stainless Steel with Screw Connections in a choice of brass, cast iron, steel, and stainless steel. They are a backpressure control valve.
The Fulflo OV-Series valves range in size from 1/2″ – 2″ and operate with liquids of any viscosity at pressures from 10 – 500 p.s.i. The valves are adjustable, mount in any position, and allow for flow rates up to 150 GPM.

A-Series Hydraulic Bypass Relief Valves
Fulflo A-Series Hydraulic Bypass Relief Valves feature both direct acting and internal pilot operated models with either screw or flange type connections. The threaded valves are available in 2-1/2″ or 3″ sizes in either cast iron or steel. The flange type valves also include a 4″ model and may be specified with 150#, 300# or 600# ANSI flanges. Note that 600# is available in steel and stainless steel only.
The direct acting valves operate at pressures to 150 p.s.i.; the internal pilot operated models at pressures to 500 p.s.i. All operate with liquids of any viscosity. The valves mount in any position and offer chatter free performance.

SVB-Series Hydraulic Bypass Relief Valves
Fulflo SVB-Series Hydraulic Bypass Relief Valves are Underwriter Listed, range in size from 3/8″ – 1″ and operate efficiently with liquids of any viscosity at pressures from 7 – 500 p.s.i. The SVB valves are of brass construction with threaded connections.
Primarily designed for use with fuel oils on oil burner service, the SVB valves may be used wherever Underwriter Listed valves are required. Each valve is pre-set to the specified pressure and is equipped with a limiting device to prevent over-adjustment. The valves can be mounted in any position.
