WEB Nordeste LTDA

Web Nordeste manufactures valves for use in well fracturing in 3-1/16" to 7-1/16" diameters, and 10,000 PSI and 15,000 PSI pressures. Frac valves have appropriate features of design and materials for performing under these harsh service conditions. They are furnished with manual handwheel command or hydraulic actuator. The manually controlled valves of sizes 4-1/16" and larger have a balanced stem and an actuating system mounted on recirculating balls. This feature allows the valve to be operated with a reduced number of turns and also faster, thus facilitating the operation and reducing damage to the closing components. They are also manufactured in groups of two or three valves that may include studded side outlets. Model T-10 HDA & T-15 HDA API 6A Gate Valves are frac valves with a double acting hydraulic actuator. The double acting piston Hydraulic actuator allows the valve to be controled fast and remotely by means of a compact control panel connected at distance. In case of not having an hydraulic pressure source, the valve has a manual override system handwheel with recirculating balls in order to open or close the valve with no excessive torque needed.

The API 6A model T15BR gate valve features a balanced stem and recirculating balls. It has been developed to manually operate large-diameter and high-pressure valves. It is used to serve as a on-off valve in oil and gas services up to 15,000 PSI. It is manufactured in sizes from 4-1/16" to 7-1/16". It is suitable for use in production trees, conduction systems and fracture trees. FEATURES: Metal to Metal seal: Metal-Metal seal between gate and seat and between seat and body. Bidirectional sealing: The gate and the seats seal in both directions. Back seat: Both stems have a metal-metal back seat, which allows for the packing to be replaced while the valve is in service. Stem packing: The non-elastomeric steam packing is unaffected by H2S, CO2, amines or any other chemical substances normally found in oil or gas wells. Its design favors low operating torque under any service condition. Easy operation: The valve opens and closes without needing excessive torque. The screw-and-nut actuating system with recirculating balls is for high performance, which allows the valve to be operated directly without the need of a gear box. This system minimizes the number of handwheel turns for operation. After the necessary number of turns required for closing the valve, the handwheel must be backed off ¼ turn. Body without penetrations: The valve body has no penetrations. For safety, the grease fitting is located on the bonnet, downstream from the backseat. Stem shear pin: The stem is protected against over-torquing by the stem shear pin. The pin can be readily replaced without disassembling the bonnet. Replaceable seats: The floating seats can be easily replaced in the field. Seat protector: A protecting ring between seat and body protects the lip of the metal-metal seal. Valves with actuator: The API 6A model T15BR gate valves can be converted into actuated valves by adding pneumatic or hydraulic actuators.

Model M3 ball valve has been designed to cover a wide range of applications as a shutoff valve for oil, gas, and water service Available in sizes from 2-1/16” to 4-1/16”, operating pressures up to 3,000 PSI with flanged, threaded or welding ends. FEATURES: Through-conduit: The internal passage of the valve is full bore, without flow restrictions. This feature reduces turbulence and headloss. It is possible to pass through the valve with any tool that can pass through the internal diameter of the pipe. Trunnion mounted: The one piece ball-and-stem construction of the M3 ball valve is the basis of its compact and robust design. This also provides greater rigidity and alignment, reducing the wear of the bearings and the operating torque as well. Low operating torque: The load produced by the pressure is borne by two self-lubricated low-friction bearings that are isolated from the flow and the environment. Internal stops: The dual-action internal stops provide high precision at the end of the stroke during opening and closing. In the open position, this prevents exposure of the seats to flow erosion. A neoprene guard prevents the entry of particles into the stem. Actuators: The M3 ball valves can be supplied with electrical or pneumatic actuators for remote operation.

Model T2 valves are used for various well or plant services requiring bi-directional valves. Model T2 valves feature a slab gate and floating seats. The pressure energizes the seats against the gate, achieving a tight seal upstream as well as downstream. When the valve is closed, the handwheel must be backed off ¼ turn.

Web Nordeste offers a broad line covering all types and sizes of API17D flanges (ISO 13628-4) used in subsea-completion equipment.

The SSV is the device that blocks or allows the flow thru the production line. It is therefore an essential part of the Surface Safety System. It´s components are a Model “S” gate valve plus an actuator. The combination of the Model “S” gate valve with an inverted port gate (the opening port is in the upper section of the gate) and our actuator, results in the SSV to be normally closed. The model S valve can be supplied with pneumatic or hydraulic actuators. The pneumatic or hydraulic operated valves, meet a wide range of applications in oil and gas services up to 10,000 PSI, they can be supplied with pilots, filters and all the necessary elements that compose and integrated surface safety system. In case of hydraulic operated valves, they can be supplied as self-contained packages. These units do not require external power source. Actuator´s main features are to have Internal sleeve protected with Non Electrolytic Nickel Coating, non-elastomeric stem packing, Metal to Metal backseat between stem & bonnet, adjustable built-in stroke limit and to be easy inspection and repairing. The pneumatic actuators are simple effect piston actuators designed to operate any gate valve. These actuators can be powered by wellhead gas, treated gas, air or nitrogen.

Diver Assited (DA) Subsea Production Manifold (MSP-DA) for oil production, rated for water depths up to 300m (985 ft). The equipment main function is to gather oil from up to 4 producing wells and also to inject gas for artificial lift. It comprises 4 independent headers for production testing and gas-lift. Design and construction according to ISO 13628-15 – 2011: Design and Operation of Subsea Production Systems: Subsea Structures and Manifolds.
