American standard pneumatic globe valve，Stop valve，Pneumatic stop valve，

Product characteristics

1, the selection of materials, in line with domestic and foreign standards, reasonable structure, beautiful shape.

2. The sealing surface of valve disc and seat is made of iron-based alloy surfacing or Stellite cobalt-based cemented carbide surfacing, with good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life.

4, the valve stem after tempering and surface nitriding treatment, has good corrosion resistance and abrasion resistance.

5. Various pipe flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.

6, the body material variety is complete, fillers, gaskets can be reasonably selected according to the actual working conditions or user requirements, can be applied to a variety of pressure, temperature and medium conditions.

7, the reverse seal is made of threaded sealing seat or body surfacing welding austenitic stainless steel, reliable sealing, replacement filler can be carried out without stopping, convenient and fast, does not affect the operation of the system.

American standard pneumatic globe valve adopts double acting cylinder, the use of upper chamber intake or lower chamber intake to remotely control the valve, easy to operate, flexible. Cylinder using medium: compressed air, nitrogen. It has the advantages of simple structure, convenient manufacture and maintenance, small working stroke, short opening and closing time, etc. The closing body (valve disc) and the sealing surface of the seat are sealed by a cone, with small closing force, erosion resistance and reliable sealing. The seat can be a replaceable seat, which can be combined with the sealing material of the closing part to meet the requirements of the working condition and extend the service life.
