Pneumatic pipeline valve with a double acting cylinder, the use of the upper chamber intake or lower air intake to remote control valve, easy to operate, flexible. Cylinder using medium: compressed air, nitrogen. Simple structure, manufacture and maintenance; working stroke is small, open and close a short time; closing body (valve) and valve seat sealing surface sealed with cone, off a small force, erosion resistance, reliable sealing. The valve seat can be used for replacing the valve seat, which can be matched with the sealing surface material of the sealing surface of the sealing surface to meet the requirement of the working condition and prolong the service life.

Structure characteristics

1, pneumatic cast steel valve selection of research, in line with domestic and international standards, reasonable structure, beautiful appearance.

2, pneumatic cast steel globe valve, valve seat sealing surface of the iron-based hardfacing alloy or Stellite cobalt based alloy surfacing and, wear-resisting, withstand high temperatures, corrosion resistance, good abrasion resistance, long service life.

3, pneumatic cast steel valve stem after quenching and tempering and surface nitriding treatment, has good corrosion resistance and scratch resistance.

4, can be used with standard pipe flanges and flange sealing surface, to meet the needs of various projects and user requirements.

5, pneumatic cast steel valve body material variety, packing, gasket can be reasonably selected according to the actual working conditions or user requirements, can be applied to all kinds of pressure, temperature and medium conditions.

6, pneumatic cast steel globe valve seal down threaded connection with the sealing seat or body welding of austenitic stainless steel and, reliable sealing, packing replacement can be carried out without stopping the machine, fast and convenient, does not affect the operation of the system.
