PRODUCT OVERVIEW
Electric V-type wafer ball valve is a commonly used product in many types of ball valves. It can not only be used as the regulation of flow medium, but also be used to cut off and switch. The electric V-type wafer ball valve is mainly assembled by fine and small electric actuator and V-type wafer ball valve. The structure of the ball valve is fixed and integrated side mounted, which is characterized by the unique V-notch in the design of the ball center. It has good shearing strength and self-cleaning function. There is no clearance between the ball core and the valve seat to ensure the sealing of the valve. The electric V-type wafer ball valve is driven by (220V, 380V) power supply, receives (4 ~ 20mA) industrial signal, and drives the valve rod to drive the ball center to rotate to complete the ball valve switch. V-type wafer ball valve is especially suitable for switching, cutting and regulating the medium on the pipes of syrup, fiber, pulp, solid particles and viscous liquid.
PERFORMANCE ADVANTAGES
1. V-type wafer ball valve is an integrated side mounted structure with strong toughness, which is not easy to cause deformation and leakage. It is equipped with upper and lower self-lubricating bearings with high bearing capacity and small friction, so as to reduce the torque of the valve.
2. Due to the shear force between the V-shaped opening and the valve seat and the smooth and round flow path in the valve cavity, the ball valve can be applied to the system control of pulp, fiber, syrup, solid particles and other media.
