Revata Engineering's 1" and 1.1/2" Wireline Retrievable Dummy Valves are manufactured to meet the requirements of API 11V1 specifications. They are installed in side pocket mandrels as a non-equalizing isolation tool. The Wireline Retrievable Dummy Valve is an isolation tool designed to blank communication between the tubing and casing. This valve can be used to blank off a side pocket mandrel.

The Dummy Valve is available in either Stainless Steel or Nickel alloys for corrosion resistance in wells with high concentrations of H2S and CO2. Packing for the valve is available for standard service or special service to suit individual well conditions.

The distance between the packing stacks is maximized to fully protect the mandrel pocket seal bores from produced fluids until they are removed from the completion. The simple design of the dummy valve allows for easy replacement of the packing and for rapid low-cost repair of its components. The rugged, solid construction and quality metals provide for a long service life.

The Dummy Valve uses BK-2 Latch. It has two sets of packing which straddle and pack off the casing in a side pocket mandrel. Communication between the tubing and casing is positively blanked off until the Dummy Valve is removed from the pocket by standard wireline procedures

Revata Engineering's Tubing Retrievable Injection Pressure Operated Gas Lift Valve are primarily controlled by injection gas pressure. The valve, when installed on outside mount tubing retrievable mandrels, is used to control gas pressure and its flow from the annulus into the tubing.

The valve is designed with a sealed chamber, including a three-ply bellows assembly that contains a nitrogen precharge, which provides the closing force of the valve. When injection gas pressure exceeds the closing force, the bellows compresses, thus lifting a valve stem off a seat allowing gas to be injected through the valve.

These valves are available in either Stainless Steel or Nickel alloys for corrosion resistance in wells with high concentrations of H2S or CO2. Elastomeric materials for the valve are available for standard service or special service to suit individual well conditions.

Ring Joint Gaskets are designed to seal by "initial line contact" or wedging action between the mating flange and the gasket. By applying pressure on the seal interface through bolt force, the softer metal of the gasket flows into the micro-fine structure of the harder flange material, creating a very tight and efficient seal.

Revata Engineering's Ring Joint Gaskets are manufactured in accordance with API-6A and ASME B16.20 specifications and come in four basic types :

R (Octagonal Type) Ring Joint Gasket

RX Style Ring Joint Gasket

BX Style Ring Joint Gasket

These basic shapes of the Ring Joint Gaskets are used in a variety of applications with pressures up to 20, 000 PSI. The dimensions are standardized and require specially grooved flanges by where a corresponding "R" or "BX" number is assigned for pipe size and pressure class for gasket identification.

Revata Engineering manufactures a wide range of composite seals based on customer requirements and applications from prototypes to production.

Composite seals are seals that incorporate the seal and another component in one part to help ease installation and reduce assembly costs.

Composite seals may include complicated parts such as Rubber bonded to various metals such as 316SS, 410, 4140 etc or bonded to a plastic or filler material.

Composite seals simplify your design with one part instead of two or more and provide better tolerances and eliminate the process of seal to component installation.

By molding the rubber seal directly to the mating metal or plastic components, various benifits can be achieved. Some of which are:

Design simplification by using one part instead of two or more.

Tighter tolerances thus avoiding tolerance stack-up.

Eliminating seal to component installation process thus reducing defects and related costs.

A hammer union comprises of a thread end, a nut end and a hammer nut which, when cinched up, compresses a composite seal assembly thereby preventing leakage. The seal assembly comprises a metal insert of a size to pass into the seal groove of conventional hammer unions and a small seal acting between the insert, the thread end and the nut end. The small seal is conveniently an O-ring or a Hammer Union Seal (Lip Seal) and is of a size that is compressed when the seal assembly is inserted into the thread end of the hammer union, thereby preventing the seal assembly from falling out of the threaded end when it is inverted.

Some profiles such as Fig 2202, Fig 1004, Fig 1502, Fig 2002, Fig 602, Fig 1002 etc require a Hammer Union Lip Seal or an 'O'Ring depending on the Size of the Hammer Union.
