5A API Dual phase stainless steel globe valve

    5A API Dual phase stainless steel globe valve belong to forced sealing valves in pipelines.By applying torque through the valve stem,the valve disc and valve seat achieve a sealed fit,thereby preventing medium leakage from the gap and achieving the cutting function.5A API Dual phase stainless steel globe valve are suitable for pipelines or devices with large pressure fluctuations,severe temperature and pressure changes due to the relatively small friction between the sealing surfaces.By adjusting the opening of the valve disc,the flow rate and flow rate of the medium can be effectively controlled to achieve throttling effect.In pipeline systems,they mainly play a role in throttling,cutting off,regulating,guiding,preventing backflow,stabilizing pressure,diverting or overflow pressure relief.They are suitable for various working conditions,such as petroleum,chemical,pharmaceutical,fertilizer,electricity,etc.,and are used to cut or connect pipelines.

5A API Dual phase stainless steel globe valve structure characteristics

① The design and manufacture of products meet the requirements of American national standard ANS1B16.34, American BS1873 and other foreign advanced standards.

② The shape of the valve body is barrel shape or linear shape. The flow shape is straight through. Low fluid resistance.

③ The closing parts (brake flap) and the sealing surface of the seat are sealed by a cone, with small closing force, erosion resistance and reliable sealing.

④ The seat can be a replaceable seat, and can be arbitrarily combined with the sealing surface material to meet the requirements of the working condition and extend the service life.

⑤ Large diameter, high pressure globe valve according to the need of closing force, the transmission mode of the valve stem adopts a lifting rod, and is equipped with a rolling bearing type using impact handwheel to reduce the closing force.

⑥ The material of the main material, the internal material, the filler and the fastener can be reasonably combined according to the user's requirements or the actual working conditions.
