Drill pipe float valves, or non-return valves, are downhole safety valves that create barriers to prevent unwanted flow of fluids up the drill string. The valve locks down the flow of fluids while the crew at the rigfloor is making or breaking connections.
The Model F Plunger Type Valve provides positive and instantaneous shut off against high and low pressure, assuring continuous control of fluid flow during drilling. For normal drilling operations, the durable Model F is the most economical choice and is available in all sizes. The "Heavy Duty" Model F Drill Pipe Float Valve is designed with a low alloy steel body that increases the life of the Drill Pipe Float Valve. It provides high impact resistance and is dimensionally identical to the standard Forum Drill Pipe Float Valve, allowing interchangeability of the trim. This type of Drill Pipe Float Valve is recommended for use with downhole mud motors.
The Model GA Differentail Pressure Monitoring Valve is identical to the Model G except for a hardened1/4 in. diameter tungsten carbide orifice bean insert in the flapper to provide automatic partial filling of the drillpipe during running in. This valve is used when monitoringthe bit head for gas pressure and/or gas pockets, allowing measurement of differential pressure when required.
