Expansion form two-way metal hard seal ball pneumatic valve structure characteristics, working principle

expansion form pneumatic ball valve on the principle of wedge blocks and dovetail groove. Expansion form two-way pneumatic valve to break the traditional metal hard seal ball ball whole rotating structure, pneumatic valve ball will open into three parts: the wedge block and two spherical cap. Its working principle is in the process of pneumatic ball valve opening and closing rotation will dovetail groove together two spherical cap that pneumatic ball valve cover break with pneumatic valve seat sealing surface, so that in the process of rotation to avoid the friction between the sealing surface, greatly improving the pneumatic valve life; After the pneumatic valve is rotated, reuse wedge shaped block would be two spherical cap to the pneumatic seat cover the seal. This kind of pneumatic valves are suitable for high temperature and high pressure conditions, safe and reliable.

expansion form a double metal hard seal ball pneumatic valve product structure features:
. Open contact seal contraction ball structure: close the bulge, open sphere shrinkage separation, easy opening and closing.
。 No friction sealing opening and closing, opening and closing zero leakage easily.
。 Sealing opening and closing without friction, prolong service life. Life is traditional pneumatic ball valve of more than five times.
。 The pneumatic valve is suitable for use in high temperature and high pressure piping system.
bulge open two-way metal hard seal ball pneumatic valve installation instructions:
. To leave the position of the pneumatic valve handle rotation.
。 Cannot be used for throttling.
。 The pneumatic ball valve with the actuator shall be installed upright.
