弗兰基的密封阀蝴蝶

Features 1.As seals are completely embedded in the valve seat, with high anti-erosion performance of medium can increase its life span more than three times; 2. Valve seat ring stacked with soft and hard stainless steel sheet and flexible graphite sheet (graphite rubber sheet, asbestos rubber sheet, etc.) of the sealing surface, it has a metal seal and the seal of the dual advantages of flexibility, both in low and high temperature work circumstances have excellent sealing performance. 3.The disc sealing cone with surfacing EDCr-B-15 carbide, makes sealing surface wear, long life, continuous opening and closing more than 10,000 times without injury. 4.Makes the valve through the appropriate choice of materials resistant to low (high) temperature, corrosion-resistant performance. 5, because all use of refractory materials, reliable fire resistance; 6. Three eccentric structure of the valve with self-locking feature, the disc related to the sealing position, immediate self-locking would not happen had bit off the disc failure; 7.Valve operation ease, low torque output, streamline design of the disc, the pressure loss coefficient is low, can be called energy-saving products; 8.Sealing the valve seat can be adjusted, is conducive to assembly and maintenance; 19. Valves and pipe connections are flanged and wafer, can be manual, but also electric, pneumatic, hydraulic or electric, gas, liquid interaction; 10. You can close the truncated media, media flow can be adjusted.
