Our Q941 electric flanged ball valves can be fully opened or closed with just a 90° rotation. The valve body passage and the connecting pipe diameter are equal and aligned, allowing the medium to flow almost losslessly. These electric flanged ball valves are suitable for two-way cut-off and regulation applications. They are divided into two main categories based on use: electric O-type cut-off ball valves and electric regulating ball valves. Structurally, they can be classified into two types: electric soft-seated ball valves and electric hard-seated ball valves. Soft-seated ball valves are primarily used for media with temperatures below 250 degrees. Hard-seated ball valves are mainly used for media above 250 degrees. Our electric flanged ball valves offer excellent sealing performance, high flow capacity, easy installation and maintenance, low flow resistance, and reliable sealing even for cut-off purposes. They are compact, lightweight, have strong thrust, powerful functionality, an integrated servo amplifier, easy operation, and high reliability. The ball valve and actuator are directly connected, featuring an internal servo system, eliminating the need for an additional servo amplifier. Operation is controlled with input/output signals of 4-20mA and a 220VAC power supply. Our electric flanged ball valves have the advantages of simple wiring, compact structure, stable operation, and reliability. The Q941F/H electric O-type cut-off ball valves and electric ball valves are important electric valve types widely used in the petrochemical industry, long-distance pipelines, and other fields. Their shut-off parts are a perforated portion of a sphere, which rotates with the valve stem to open or close the valve. The Q941F/H electric O-type cut-off ball valves and electric ball valves can cut off and control the flow of media in transportation pipelines for oil, chemicals, papermaking, metallurgy, wastewater treatment, tanker trucks, and more.

Electrical Flanged Ball Valve - Product Features
(1) Fluid resistance is low; among valve types, ball valves have the least fluid resistance. Even constricted ball valves exhibit minimal fluid resistance.
(2) Thrust bearings reduce the friction torque of the valve rod, enabling long-term operation with balance and flexibility.
(3) The valve seat has excellent sealing performance, featuring a sealing ring made of materials such as polytetrafluoroethylene, which ensures easy sealing. Moreover, the ball valve's sealing capability increases with the increase of medium pressure.
(4) The valve stem seal is reliable. Since the valve stem only rotates and does not move up and down, the stuffing box seal of the valve stem is less prone to damage, and its sealing ability increases with the increase of the medium's pressure.
(5) Due to the self-lubricating properties of materials like polytetrafluoroethylene, friction losses with spheres are minimized, resulting in extended service life for ball valves.
(6) The valve stem and the stem head step prevent the valve stem from extruding. In case of a fire causing damage to the valve stem seal, the step can still form a metal contact with the valve body, ensuring the stem seal.
