Revata Engineering offers a wide variety of latches for installing wireline retrievable devices in side pocket mandrels. These Latches are manufactured to meet the requirements of API 11V1. They are specifically designed to lock in place when located in either 180 degree or 360 degree latching pocket profile.   To retrieve a latch and attached flow control device, upward jarring of the tool string sheers the release shear pin permitting the locking mechanism to disengage from the latch locking profile. 180 degree latch pocket profile have a spring loaded ring style latching mechanism. A ported ID is included in some designs for applications requiring a communication path between the latch and top of the attached flow control device.

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   FEATURES & BENEFITS: Standard construction is stainless steel, with monel or other premium materials optional. Wireline retrievable by standard methods. Use standard top latches. Temperature rating of 250°F (121°C) (Standard Service) Maximized packing separation for complete seal bore protection in the mandrel pocket. Standard Neoprene packing with other materials available. Compatible with other manufacturers side pocket mandrels.   APPLICATIONS: To blank off the tubing while completing the well / prior to pressurizing the tubing to set a hydraulic set packer. To blank off the tubing for production until gas lift valves are required. To allow the tubing to be pressurized in various situations. To isolate the tubing and casing during single alternative production sequences. To isolate tubing and casing flow for test purposes during multi-point water flood or gas injection modes. Allow for production prior to installation of the Gas Lift Valves Isolate tubing from casing annulus during remedial work such as acidizing or fracturing.

Revata Engineering manufactures multiple-lip (chevron) Seals or Vee Packings that consist of a group of endless rings and are usually used for sealing rods, pistons, plungers in hydraulic cylinders and hydraulic presses. V-Packings are used for low or high pressure applications with Single or Double acting cylinder.   V-Packings are also used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.   The hinge-line action of Vee-Packings that enables immediate reaction even to minor pressure changes is very distinctive and exclusive to a Vee-Packing design. Each individual lip of a Vee-Packing set reacts independently to pressure thus effecting aseal automatically. In case of multiple lip configurations, pressure is automatically distributed thus effecting a seal along the shaft. Vee-Packings also premit automatic reaction to shocks from high pressure and overloads.   The Vee-Packing is a combination of Base Seal, the Vee-Ring at the center and the Pressure ring. The Vee-Ring is the main seal that can retain high and low pressures while the base seal supports the center ring from getting extruded during high pressure applications. The Pressure Ring helps in retaining the Vee Packing profile and distributing pressure equally.   We stock a wide range of Vee Packing along with their Male and Female Adapters to suit various customer requirements.   Some of the standard materials in which Vee Packings are available are:  Graphite, Moly, Glass filled PTFE V-Packing  Filled PTFE (Filled with Glass, Graphite, Carbon, Moly etc) V-Packing  Homogeneous NBR 90 Shore A V-Packing  NBR Vee-Packings with Fabric reinforcement V-Packing.  Viton V-Packing.  Aflas V-Packing.   The right material for the Vee Packings is selected based on various factors some of which are:  Operating Pressure  Operating Temperature  Tpe of Gases or Fluids within operating medium etc.  Normally Fabric Vee Packings are used for High Pressure applications while Homogeneous Vee Packings are used for Low Pressure applications.   Installation:  A properly installed Vee Packing set will usually provide better results compared to other lip-type seals. Each Set contains a nmber of Vee-Rings based upon the pressure plus male and female adapters.  The Vee-Rings in each set are referred to as Pressure Rings.  Properly installed Vee Packings will generally outperform other lip-type seals. They are always installed in sets. Each set contains a number of V-Rings (based upon the pressure) plus male and female adapters. The V-Rings in each set are referred to as pressure rings.

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.   Please refer to our SPARES FOR GASLIFT VALVES for more details on spares available for Gas Lift Valve repair and maintenance.   FEATURES & BENIFITS: Our WLR IPO Gas Lift Valves are available in Stainless steel or premium materials. The Gas Lift Valves use Three-ply Monel® 400 bellows. The Bellows connections are Silver Brazed. Mechanical stop feature prevents the bellows overstroke. A viscous Silicone based fluid is used to create a fluid shear which dampens the bellows preventing damage to it as well as preventing pounding of the stem to the seat. Tungsten carbide balls ensure long lasting operation. The replaceable floating Monel® 400 seats. Tungsten Carbide seats are available upon request. Optional reverse flow check valve. Pressure rating up to 1,800 psi (124 bars) test rack open. Temperature rating of 250°F (121°C) (Standard Service) Compatible with other manufacturers of side pocket mandrels.
