Pneumatic triple eccentric butterfly valve product overview
Pneumatic triple eccentric butterfly valve by the piston actuator and triple eccentric metal sealing valve body composition, the structure using the 3 d design of principle of heart valve seat adopt hard and soft sealing compatible multi-level structure, exquisite processing, the craft is advanced. Pneumatic triple eccentric butterfly valve with pneumatic valve positioner, the input control signals (20 madc or 1-4-5 VDC) gas source can control operation, also can match lead limit switch, solenoid valve, triple pieces and 0.4 0.7 MPa gas source switch operation can be realized, and sent out to passive contact signal indicates the switch valve. Pneumatic triple eccentric butterfly valve By the valve body, disc, multi-level seat, valve stem, drive mechanism and so on the main parts, long life, energy-efficient and butterfly valve. Pneumatic triple eccentric butterfly valve is widely used in metallurgy, electric power, petroleum, chemical, air, gas, flammable and corrosion medium such as water supply and drainage pipeline.
Pneumatic triple eccentric butterfly valve The main features
1, the valve adopts triple eccentric sealing structure, less wear of the seat and disc.
2, selection of sealing ring made of stainless steel, has the dual advantages of metal hard seal and elastic sealing, no matter in the case of low and high temperature, has good sealing performance, corrosion resistance, long service life, etc.
3, butterfly plate sealing surface using cobalt-based carbide surfacing, sealing surface wear resistance, long service life.
4, large diameter butterfly plate adopts the structure supporting structure, high strength, large flow area, small flow resistance.
5, pneumatic triple eccentric butterfly valve has two-way sealing function, installation is not restricted by medium flow direction, and is not affected by spatial location, can be installed in any direction.
6, driving device can transfer (rotate 90 ° or 180 °) installation, making it easy for users to use.
