Product Description

Product Description

  Flange diaphragm valve is a special form of cut-off valve, and its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts, so it is called diaphragm valve.

  The most prominent feature of the valve is that the diaphragm sings the inner cavity of the lower part of the body cavity and the upper part of the cover, so that the wide rod, valve suit and other parts located above the diaphragm are not corroded by the medium, eliminating the packing seal structure, and will not produce media leakage, this valve is made of rubber or plastic soft seal diaphragm, sealing is better.

  However, because the diaphragm is a wearing part, it should be replaced regularly depending on the characteristics of the medium. In addition, limited by the diaphragm material, the diaphragm valve is suitable for low pressure and relatively low temperature occasions. Diaphragm valve according to the structural form can be divided into: house type, straight flow, cut-off, straight through, ram type and right Angle type six; The connection form is usually flange connection; According to the driving mode can be divided into manual, electric and pneumatic three, of which pneumatic drive is divided into normally open, normally closed and reciprocating three
 

  Through 360° rotary handle, the ball body which have transfixion cavity and precise manufacture will open or close the valve, reaching the purpose of controlling the flow rate of medium.

  There are various standard valve series can be supplied, they are the DIN standard series,3A standard series, SMS , ISO/IDF , BS/RJT , ASME/BPE standard etc. The constitute elements of ball valve always included: one handle, one ball body with transfixion cavity, valve body, valve central spindle and spindle shaft seal. The specification of ball valve series are welded ball valve, clamped ball valve, threaded ball valve etc.
