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 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.
