美国BOLON气动蝶阀

Soft seal butterfly valve imported without pin only - the United States of America BOLON authorized agent selection principle:

(1) the butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, fast switching, 90 ° reciprocating rotary, small driving torque characteristics, for truncation, switched on, adjust the line of medium, has a good flow control characteristics and close sealing performance.

(2) the butterfly valve to transport slurry, accumulation of fluid in the pipe outlet at least. Low pressure, can achieve a good seal. Good regulation performance.

(3) the streamline design of the disc, the fluid resistance loss is small, it is a kind of energy-saving products.

(4) pole structure of the stem to pass, after quenching, with good mechanical properties and corrosion resistance, scratch resistance. Butterfly valve opening and closing only when the valve stem rotates without lifting operation, easy to damage the stem packing, sealing and reliable. And disc cone pin fixed, extended end to prevent out of design, in order to avoid accidental fracture at junction of stem and disc stem collapse.

(5) connections are flanged, wafer connections, welded connections and lugs on the clip connection.

(6) drive in the form of manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage actuator, can realize remote control and automation.

Import without pin soft seal butterfly valve - the United States of America BOLON only authorized agents products:

(1) convenience sluicegate rapidly, fluid resistance small, labor-saving, can often operate.

(2) simple structure, small volume, light weight.

(3) to transport slurry, accumulation of fluid in the pipe outlet at least.

(4) under low pressure, can achieve a good seal.

Import without pin soft seal installation points only butterfly valve - the United States of America BOLON authorized agent:

(1) at the time of installation, the valve to turn off at the stop position.

(2) the open position the disc rotation should be determined.

(3) with a bypass valve butterfly valve, open the bypass valve opening should be first.

(4) shall be installed according to the manufacturer's installation instructions, the weight of a large butterfly, set a solid foundation.
