The main technical parameters of the API600 standard gate valves and API American standard gate valves produced by RTV Ruitong Valve are:
① The product design and manufacturing comply with the requirements of the American National Standard ANSIB16.34 and the American Petroleum Institute Standard API600/API6D.
② Compact structure, small volume, good rigidity, and safe and reliable sealing.
③ The closing element (gate) adopts an elastic structure, which can automatically compensate for valve body deformation caused by abnormal loads or temperatures during operation. Therefore, the sealing is reliable and will not produce gate wedges.
④ Manual valves with nominal diameter greater than or equal to NPS1011, pressure class 400 pounds, and nominal diameter greater than or equal to NPSS611, pressure class 150-2500 pounds, are equipped with rolling bearings in their operating devices for easy opening and closing.
⑤ The materials of the main body, internal components, fillers, gaskets, and fasteners can be reasonably combined according to user requirements or actual working conditions.
⑥ The valve seat can be a more lift type valve seat, and can be matched with any combination of sealing surface materials to meet working conditions and extend service life.
