NDQF-2 Pneumatic Fast Closed Ball Valve

1.Summarize

NDQF-2 pneumatic fast closed ball valve as a functional element of fast opening and shutting is widely used in the pipe, such as, pipe of oil boiler in thermoelectric power station, each kind of oil quality fuel gas system, air and steam pipe. It also can satisfy other line to realize long distance common control, such as, petrifaction, metallurgy,and chemical line.

The energy power comes from compressing air, and its feature as:  Thermos table, the high pressure, the resistance is small, good leak-proof quality, compacted structure, opens shuts rapidly, steady and safe reliable work. The valve switch has the position indication and the signal feedback, is the industrial system realizes the remote control and the automatic control ideal functional element.
