1, see fit and use rubber or molecular compound plastic soft tightly closed manufacturing diaphragm, tight sealing ability is better. Q: a unique place of pneumatic diaphragm valve, the diaphragm to the lower body inner cavity and the upper cover inner chamber is separated, the located above the diaphragm of the stem and disc parts from corrosion medium, such as eliminating the packing tightly closed structure, and do not initiation media leakage. 4. General is not suitable for temperature is higher than 60 degrees and organic solvent and strong oxygen medium pipeline, also not suitable for used in high pressure pipe pneumatic diaphragm valve. 。 Because the diaphragm for wearing parts, should be periodically change depending on the nature and the medium of special. 3, according to the structure pattern can be divided into: the diaphragm valve house type, straight flow, by type, Marine valve straight-through type, ram, and an Angle of 90 degrees of six; Generally for flange petition petition mode; According to the driving form can be divided into manual, electric and pneumatic three, there is divided into pneumatic drive often open, often closed and reciprocating three. 2, the diaphragm material limit, the diaphragm valve is suitable for use in the occasion of relatively low pressure and temperature is not high. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
