Electric O-type Shut-off Ball Valve Product Overview
The ZRSO Electric O-type Shut-off Ball Valve produced by our company adopts an O-type ball core structure, hence it is also known as an electric switch ball valve. The electric O-type shut-off ball valve features a compact structure, small size, light weight, short distance between the valve seat and the end flange, minimal material retention, and excellent sealing performance. The electric switch ball valve is suitable for on/off applications. The valve is directly connected to the actuator, and the electric actuator does not require a servo amplifier; it can be controlled by inputting a 220V AC power supply. The electric O-type shut-off ball valve offers advantages such as simple wiring, compact structure, small size, light weight, low resistance, and stable and reliable operation. It is typically used in applications requiring strict sealing. The electric O-type shut-off ball valve and electric switch ball valve are widely used in automatic control systems in industries such as chemical, petroleum, pharmaceutical, and light industries.
