1R, 2F-3R, Drill Pipe Float Valve Plunger Type F, and Flapper Type G, GA for pressure monitoring with repair kits API standard

Product Description

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 G "Flapper Type" Full Open Valve incorporates a specially designed flapper which opens quickly and fully to provide a completely unrestricted bore through the valve. The Model G is especially good for use with highly abrasive fluids. When circulation stops, the flapper closes instantly to prevent cuttings from entering the drill string and plugging the bit. The valve opens when the first joint is raised out of the hole assuring the first joints drain and are not pulled wet. The flapper-type valve complements primary blowout prevention equipment to provide complete internal pressure control.

 

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.
