          First, the American standard large-diameter gate valve Introduction

          Gate valve pressure, temperature and caliber range, especially for medium and large diameter pipe.

          From the simplest American standard valve to a very complex automatic control system used in a variety of American Standard valves, the variety and specifications are quite diverse. The valve can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, muds, oils, liquid metals and radioactive media.


           Second, the American standard large-diameter gate valve 
          product structure characteristics

          1, product design and manufacture according to API standards, reliable sealing, excellent performance, supporting the use of imported equipment.

          2,600Lb above gate and valve seat seal with stellite stellite (cobalt-based hardfacing), wear-resistant, high temperature, corrosion resistance, good scratch resistance, long life

          3, the stem by quenching and nitriding surface treatment, have good corrosion resistance and scratch resistance.

          4, using wedge-type flexible gate structure, large diameter set rolling bearings, opening and closing easily.

          5, the full range of valve materials, packing, gasket reasonable selection according to the actual conditions or user requirements, can be applied to a variety of pressure, temperature and medium conditions.

          6,1500LB, 2500LB The use of self-tight pressure chamber sealed structure. Sealing performance increases with increasing internal pressure, high reliability.

          7, inverted seal with stainless steel threaded seal seat or body made of welded austenitic stainless steel, reliable sealing, packing replacement and maintenance can be carried out without downtime, convenient and quick does not affect the system operation.
