PRODUCT OVERVIEW
Electric ceramic ball valve is composed of three-stage ceramic ball valve and intelligent regulating electric actuator. The ball center of the ball valve is all ceramic, and the flow channel is fully lined with wear-resistant ceramic. (its hardness is above hra88, second only to diamond) has the properties of wear resistance, oxidation resistance and erosion resistance. The valve rod is finely ground, the surface is subject to anti-corrosion nitriding or quenching and tempering treatment, and the built-in buffer compensation elastic washer ensures stable and good sealing performance. The working principle is to receive (4 ~ 20mA) industrial signal and drive the actuator with 220V or 380V power supply voltage to rotate the valve rod ball center (0-90 °) to complete switching and adjustment. It is suitable for all kinds of acid, alkali, salt liquid and gas medium environment. The hard sealing valve is especially suitable for medium environment with particles and fibers.
PRODUCT FEATURES
1. The ball core and flow channel are structural ceramic materials, with hardness (Rockwell hardness hra88), second only to diamond. The ball center has high precision. After lapping with the valve seat, it has good sealing performance by using the self lubricity of ceramics.
2. It completely changes the shortcomings of metal hard seal ball valve, such as easy leakage, large torque and non-corrosion resistance of sealing surface. Ceramic has good wear resistance, high reliability and long service life, which is 2-4 times that of titanium alloy valve and Monel valve.
