drill string safety valve for sale

Packard safety valves are designed to either stab into the drill pipe or tubing at the rig floor or are used as part of the drill string to shut off a well kick. Use of these valves in the drill string enhances rig safety.

The Packard two-piece safety valve offers the convenience of a two-piece body for easy maintenance. Its full bore also allows the unrestricted flow of drilling fluid � reducing wear on critical parts while providing unrestricted access for downhole tools.

Packard International�s safety valves are built with enough length on each end to allow fully recutting the connections in the event of damage to the threads or shoulders where sealing takes place.

High and low pressure sealing is assured by the Teflon and metal sealing system of the ball and seats. The ball and lower seat float while the upper seat is fixed in the body. This floating/fixed design aids in low pressure sealing and enables the operator to pressure balance the valve under full rated working pressure.

Packard International�s safetyvalves are designed for even the harshest drilling conditions; however, it is suggested that parts most subject to wear and tear be replaced regularly.

The IBOP, also called Gray Valve or BVR, is a back pressure valve used in the drill string to prevent the well from flowing uncontrollably up the drill string. It is generally used in 2 ways:

Below the rig floor without a plug when connected in the drill-string. It can be left in the drill string as long as necessary to re-establish control of the well-pressure balance.

The RDCV, also called Dart Valve or a Back-Pressure Valve, controls backflow through the drill pipe during a kick or when tripping pipe into the hole against pressure. Check-valve compatibility should be checked with Kelly Cock free passage.

Full Opening Safety Valve (short for FOSV) is a ball type safety valve used to stop flow through the drill string when the drill string is being withdrawn from the well.

Our FOSV is dual body full-opening safety valve, so it does not interfere with the running of tools such as core barrels or survey instruments. It is designed to be stabbed into the top joint of drill pipe or tubing string at the rig floor and closed quickly in case a well kicks.

The ball-type design permits the valve to be compact, easy to handle, and yet have great strength. Standard test pressure is 10,000PSI, but higher pressure ratings are available.

In 2006, Forum purchased the Baker SPD product line. Forum continues to manufacture the products formerly known as Baker SPD under the SPD name and offers a complete line of float valves, repair kits, and puller assemblies for a wide range of drilling situations and operating conditions. We are the premier provider of “Certified” drill pipe float valves that includes high- and low-pressure testing, serialization, and full material traceability, providing improved reliability and failure prevention.

High-performance drill pipe float valves are essential for consistent fluid control throughout drilling. Also known as non-return valves, this type of downhole safety valve prevents undesirable fluids from backing up into the drill string any time your crew is modifying connections.

Oteco valve bodies are manufactured for today’s increasingly harsh drilling environment. All valve bodies are cast out of ductile iron or a low-alloy carbon steel and are heat treated to a hardness equal to or less than 22 Rockwell C (≤ 22 Rockwell C 2 HR) to address the corrosive effects of hydrogen sulfide gas (H2S). Oteco’s integral valve bodies are manufactured from a one-piece casting and are not welded together the way some other competitors produce their bodies. This means that customers receive a superior and more reliable valve body.

All of Oteco’s plunger valves are machined from one solid piece of material to produce a more reliable float valve and reduce the risk of downhole valve failure.

All Oteco standard-service flapper valves are made of low-alloy steel and then case hardened for wear resistance, thus giving a longer operating life.

Inconel® springs come standard on all our valves. Inconel® springs are significantly more resistant to corrosion when compared with the standard service springs provided by most other manufacturers. Inconel® springs are also good for sour-gas (H2S) applications.

All Oteco drill-pipe float valves and replacement parts are manufactured to standard industry dimensions and interchangeable with other major manufacturer’s parts.

The Model F is a plunger-type float valve that provides a positive instantaneous shut off, providing constant fluid control while drilling. The Model F is a reliable and economical selection under standard drilling operations.

The Model FC Automatic-Fill plunger-type float valve incorporates a unique key assembly and slotted valve stem to hold the plunger open during run in of the drill pipe and allows the pipe to fill from the bottom, saving time, reducing mess, and avoiding hazards. The plunger is automatically released once circulation begins.

The Model FA Pressure-Monitoring plunger-type float valve has a special port running through the plunger of the float valve. This valve is used when monitoring the bit head for gas pressure and allowing differential pressure measuring when required. The port also permits partial automatic fill during run in.

The Model G is a flapper-type float valve that, when opened, offers an unobstructed bore through the float valve. The uniquely designed flapper closes rapidly to prevent shavings from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control. The valve will fully open when the first joint is raised from the hole, preventing pulling wet joints.

The Model GA Pressure-Monitoring flapper-type float valve is indistinguishable from the Model G with the exception of a tungsten-carbide insert in the flapper valve. The insert has a quarter-inch orifice through the center that allows for differential pressure monitoring. The orifice also allows for partial automatic filling of the drill pipe during run in.

The Model GC Automatic-Fill flapper-type float valve incorporates a unique self-releasing key assembly that holds the flapper partially open during run in, allowing the pipe to fill from the bottom. This eliminates the need for filling the drill pipe from the top, saving time and money. The valve will fully open when the first joint is raised from the hole, preventing pulling wet joints while avoiding the environmental and safety risks related to having mud on the rig floor. The valve can be run with the automatic-fill option or in the standard, closed position.

The Model GCA Automatic-Fill/Pressure-Monitoring flapper-type float valve includes all the advantages of the Models G, GC, and GA. An unobstructed bore through the float valve, when open, permits automatic partial filling of the drill pipe from the bottom and measuring differential pressures when necessary.
