Brand: Yibiao valve Product Model: YD71X-16

Product introduction
The soft seal butterfly valve is a regular butterfly valve prioritized for pipelines, with simple structure and small flow resistance coefficient. The flow rate of special new tends to straight line, will not retain debris. And light weight, easy to install, the advantages of driving torque is small. Centerline soft seal butterfly valve can be used for cutting off the medium, but also can be used to regulate the flow of the medium. Drive device according to user requirements, respectively, can be manual, electric, pneumatic, hydraulic and other ways. Selection of parts of different materials, with different materials of the seal, can adapt to different media, working conditions, so that the cost and performance to achieve better results.
Clamped butterfly valve adopts centerline structure without eccentric design, which is characterized by low operating torque and remarkable economy of actuator configuration. Rubber valve seat has good balance and support, effectively avoiding the damage to the rubber caused by uneven force, when the valve is fully closed, the rubber is in a better compression state to maintain zero leakage. The circumferential sealing surface of the butterfly plate is processed to a high degree of finish, and the friction coefficient of the rubber seat has a long service life. The rubber sealing surfaces at both ends of the valve are protruding from the flange surface, so the valve does not need additional rubber sealing gaskets when installing in the pipeline. Simple structure, compact, light weight, easy to install and dismantle. Installation in any position, can realize two-way sealing.
