The advantage of metal hard seal pneumatic valve

Metal metal hard seal pneumatic valve is to use a 'U' shaped stainless steel ring, the precision of the elastic sealing ring and three-dimensional eccentric contact after polishing plate. Solve the traditional eccentric pneumatic valve in the opening and closing 0 ° ~ 10 ° the deficiencies of the seal face is still in the sliding contact friction, achieve plate in open the sealing surface, the separation, close contact with the sealing effect, prolong the service life, good sealing performance.

metal hard seal pneumatic valve product advantage description

1, from the original iron to pneumatic valve body shape after 15 craft, layers of control, to ensure that achieve ZG250 - pneumatic valve body material 485.


2, CNC lathe processing board, the sealing ring for hard and soft cascading metal ring, has the dual advantages of metal and elastic sealing, to ensure that under the environment of high temperature and low temperature has good sealing performance.



3, USES three eccentric structure, pneumatic valve seat plate and the friction of the tiny, have the close tight sealing function, improve the service life of the seal.



4, pneumatic valve sealing surface surfacing welding stainless steel, cobalt base carbide way, make sealing surface wear resistance, long service life.



5, pneumatic valve plate and valve seat sealing surface for the oblique cone structure, in the pneumatic valve plate oblique cone surface welding heat resistance, corrosion resistant alloy material, to improve overall performance of pneumatic valve.



6, pneumatic valve shaft hole installation copper collar, through precision machining, solved the pneumatic valve in the two-way exchange medium sealing problems in the transport process, this kind of structure effectively compensate the collar and tolerance zone between the pneumatic valve and pneumatic valve stem under medium pressure elastic deformation, ensure the normal order of the pneumatic valve opening and closing.



7, pneumatic valve stem is made of stainless steel material to make conditioning treatment after double the strength of the pneumatic valve stem, low price because of the pneumatic valve rod deformation caused by the opening and closing, leak problem.



8, each product 100% two sealing pressure, hydraulic pressure after pressure first, to ensure that each pneumatic valve reaches zero leakage standards.



9, large diameter pneumatic valve in the flange shaft sleeve with sliding bearing, reduce the problems due to the torque caused by the pneumatic valve opening and closing the inconvenience.



10 pneumatic valve, metal hard seal after the completion of production, each product use lead-free paint three times of primers and paint coating, to ensure the brightness of the product appearance and corrosion resistance.
