Our ZRSO electric O-type cut-off ball valves feature an O-type ball core structure, hence also known as electric switch ball valves. These valves are characterized by their compact design, small size, light weight, close distance between the valve seat and end face flange, minimal material retention, and excellent sealing performance. Suitable for two-way cut-off applications, the valve is directly connected to the actuator, eliminating the need for a servo amplifier. Operation can be controlled with a 220VAC power supply. The electric O-type cut-off ball valves offer simple wiring, compact structure, small size, light weight, low resistance, and stable, reliable operation. They are commonly used in applications with stringent sealing requirements and are widely applied in automatic control systems across industries such as chemicals, petrochemicals, and light industry.
