Introduction: WB310 triple eccentric butterfly valve manufacturers adopt triple eccentric structure. In addition to the two eccentricities of the stem and disc, the sealing surface of the disc and seat is in the shape of an oblique round table (this is the third eccentricity of the so-called triple eccentricity). When the valve is closed, the valve plate is pushed forward due to eccentricity, and the valve plate and the valve seat do not produce friction during the closing process, and the valve plate is directly pressed on the valve seat, so as to ensure the service life of the valve; In addition, because the sealing ring of this valve (whether installed on the valve seat or on the valve plate) has a certain elasticity, and there is a small amount of gap between the boss and the elastic ring in the elastic ring, the elastic ring can be slightly displaced; When the valve is closed, the elastomer sealing ring can automatically move to a uniform position under force due to the closing force; Coupled with a small amount of deformation of the elastic ring, the sealing ring at the valve seat is evenly stressed and reaches a sealed state.
Features:
Bi-directional sealed, in accordance with API598 and ANSI B16.104
Frictionless opening and closing, long life
Multi-layered sheet metal
Sealing structure and all-metal sealing structure
The sealing ring is replaceable, easy to maintain and repair.
Inherently refractory construction
Torsional sealing, low closing torque
