800LB globe valve is due to the small friction between the sealing surfaces in the opening and closing process, relatively durable, small opening height, easy to manufacture, easy maintenance, not only for low and medium pressure, but also for high pressure. Its closing principle is to rely on the pressure of the valve bar, so that the disc sealing surface and the valve seat sealing surface close to prevent the flow of media.
● Stronger, leak proof bolted body bonnet joint ensures joint tightness with a higher bolting torque.
● Body guided disc eliminates side thrust and provides longer disc, seat and body life.
● Impactor handwheel for tight shut off.
● Designed to ASME B16.34.
● Body made of superior strength forgings and optional cast steel.
●stem seal offers tight seal with little to no maintenance over long periods of time.
● Optional live-loading of packing.
● Non-rotating stem.
● Hard faced seating faces resist erosion.
● Available with provision for seal weld.
● Other sizes and pressure classes available. Contact the company for specifications.
