1) Description
The valve is a disc - shaped disc, in the valve body around its axis rotation, so as to achieve the opening and closing or regulating role.Driving mode: manual, pneumatic, electric.
2) Features
1, Novel and reasonable design, unique structure, quick opening and closing;Bidirectional sealing performance is good, torque value is small, parts processing performance is superior.
2, small operating torque, easy to operate, labor saving dexterity;Flow characteristics tend to straight line, good regulation performance.
3, flange connection installation is convenient, vertical, horizontal installation can be.
4, the sealing parts can be replaced, the sealing performance is reliable to achieve zero leakage of two-way sealing.
5, sealing material aging, corrosion resistance, long service life and other characteristics.
6, the valve can be used for pipe end as a vent valve, reliable performance.
3) Execution standard:
Design standard | MSSSP-67,BS5155,BSEN593 |
Flange end | EN1092-2.ASME B16.1/16.42.AS4087 |
Face to face | API 609.DIN3202 |
Inspection testing standard | EN12266/API598 |
Technical parameters:
Nominal diameter | DN50~DN1200 |
Nominal pressure | PN10/PN16/PN25 |
Operating temperature | -10°C~120°C |
Seal test | 1.25PN |
Shell test | 1.5PN |
Suitable medium | Water |
1) Operating principle:
The rotary center of the disc (that is, the center of the stem) is located on the center line of the valve body and the section of the sealing surface of the disc.Seats are made of synthetic rubber.The sealing surface of the butterfly plate squeezes the synthetic rubber seat when it is closed, which causes the seat to produce elastic deformation, thus forming the elastic force to ensure the seal of the butterfly valve for the sealing specific pressure.Flange butterfly valve sealing structure using teflon, synthetic rubber composite seat, its characteristic is that the flexibility of the valve is still provided by synthetic rubber and the use of teflon friction coefficient is low, not easy to wear, not easy to aging and other characteristics, so that the butterfly valve life can be improved.
