D673H/F Pneumatic Hard Seal Clamp Butterfly Valve features
1, the valve adopts three eccentric seal structure, the valve seat and disc almost no wear, with the more the more tight sealing function.
2, the ring made of stainless steel, with the advantages of both metal seal and flexible seal, both in the case of low temperature and high temperature, have excellent sealing performance, with corrosion resistance, long service life and so on.
3, the butterfly plate sealing surface using welding cobalt-based hard alloy, sealing surface wear-resistant, long service life.
4, Large-format butterfly plate frame structure, high strength, large flow area, small flow resistance.
5, the valve has a two-way sealing function, the installation is not subject to restrictions on the flow of media, but also the location of space, can be installed in any direction.
6, the drive can be multi-station (rotated 90 ° or 180 °) installation, user-friendly.
D673H/F Pneumatic Hard Seal Clamp Butterfly Valve principle
Electromagnetic valve to control the pneumatic actuator, the valve stem to achieve the purpose of turning 90 °.
Cylinder with 1/4 rotary cylinder, adjustable angle 1 ° ~ 5 °.
