VQ940H overview:
The ball core is V shape, can realize linear adjustment, adjustable range. When the valve is closed, the wedge between the V notch and the valve seat is provided with a self cleaning function, and the ball core can be prevented from being stuck. The utility model is suitable for the control of paper pulp and waste water, and comprises a fiber and particle solid suspension medium and a powder granular medium. Equipped with POLOVO cylinder piston actuator, simple structure, large output torque. This series of ball valve according to the sealing performance is divided into soft seal and hard seal; according to the regulation mode is divided into adjustable type and cut off type, cut off by the role of the form of single action and double action type, adjust type for double action. Single function of the unique advantage is that once the power source failure, the ball will be in accordance with the requirements of the control system is automatically closed or open position. Products are widely used in electric power, petroleum, chemical, paper, textile, food, pharmaceutical, aerospace and other fields.
Product features:
1, with elastic load pressure auxiliary sealing seat to ensure that the valve seat and ball core from the end to the close contact
2, with the overall structure of the valve body, there is no possibility of potential leakage
3, with the percentage of characteristics, has a wide range of control and stable control process, can be widely used in a variety of processes
4, the valve stem and the ball core is connected with the involute spline, when the tooth profile is loaded, the radial force on the teeth can play the role of automatic centering, and the force of each tooth to make uniform high strength, long life.
