The high pressure fluid control parts produced by our company mainly include the following types:
Low Torque Plug Valve
Low torque plug valve is based on the technology from FMC and SPM, forged from high strength alloy steel. Widely used in cementing, fracturing, acidizing, coiled tubing.
Wellhead Check Valve
Wellhead check valve is used in high pressure lines to control one-way flow and prevent fluid from flowing back in pipeline, while protecting the pipe line and equipment safety, The core component of check valve is foraed by stainless steel with advanced erosion and abrasion-resistant characteristics, The seals use secondary vulcanization resulting in ultimate sealing.
Low Torque Plug Valve
Low torque plug valve have many advantages, including: Power is saved because low-torque ball valves require less energy to operate. They facilitate smoother and faster system operation. Their sturdy construction requires fewer repairs and lasts longer. These valves are used in many different industries since they fit with a wide variety of actuators. By using them, energy costs are reduced and systems become more environmentally friendly and cost-effective.
Wellhead Check Valve
Wellhead check valve have many advantages, including: They primarily prevent backflow, which protects equipment and maintains pressure. This prevents issues like water hammer and allows for system isolation during maintenance.
Application of High Pressure Fluid Control Parts
Low Torque Plug Valve
Low torque plug valve can be used for a variety of purposes, including: They also provide a tight seal, which is necessary for handling gasses. Petroleum and chemical industries: Plug valves can manage various fluid properties, including corrosive, flammable, toxic, and thick fluids. This makes them ideal for the petroleum and chemical industries.
Wellhead Check Valve
Wellhead check valve can be used for a variety of purposes, including: Wellhead check valves are crucial components in oil and gas operations, primarily used to prevent backflow and maintain one-way fluid flow in wellheads and related equipment. They ensure the integrity of the well, protect equipment, and enhance safety during various operations. Check valves prevent pressure surges caused by backflow, which can damage pipelines, wellhead equipment, and other components.
