Product Description: Sichuan Zigong Valve Ball Valve Q641F or Q647W Quick Shut-off Valve Pneumatic Ball ValveBefore consulting or purchasing, users are requested to provide accurate parameters such as caliber, pressure, connection method, operation method, and main body material. The above prices are reference prices, and prices vary for different models. Additionally, this product is a customized product with a production cycle, and delivery times also vary. Therefore, for specific model prices and delivery times, please call for consultation.A pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The pneumatic actuator operates relatively quickly, so it is often referred to as a pneumatic quick shut-off ball valve. Pneumatic ball valves are typically equipped with various accessories, such as solenoid valves, air source treatment triple units, limit switches, positioning devices, control boxes, etc., to enable local control and remote centralized control. The valve can be controlled from the control room without the need to manually operate it on-site, saving labor and time. Pneumatic ball valves are classified by material into: stainless steel pneumatic ball valves, plastic pneumatic ball valves, carbon steel pneumatic ball valves, cast iron pneumatic ball valves, etc. They are classified by the number of passages into two-way pneumatic ball valves, three-way pneumatic ball valves, and four-way pneumatic ball valves.Pneumatic ball valves only require a pneumatic actuator with an air source to rotate 90 degrees and a small torque to open or close the valve. The smooth inner cavity of the valve body provides a low-resistance, straight-through flow path for the medium. The main features of pneumatic ball valves are their compact structure, ease of operation and maintenance, and suitability for media such as water, solvents, acids, and natural gas, as well as other media like oxygen.Pneumatic ball valves are primarily used in pipelines for quick shut-off, distribution, and changing the flow direction of the medium. They have the following characteristics:1. Low fluid resistance, with a resistance coefficient equal to that of a pipe section of the same length.2. Stable sealing performance, simple structure, small size, and light weight.3. Easy operation, quick opening and closing, and convenient for remote control.4. Easy maintenance, with a simple structure and generally movable sealing rings, making disassembly and replacement convenient.5. Since the power source of pneumatic ball valves is gas, typically at a pressure of 0.2-0.8MPa, if the pneumatic ball valve leaks, the gas can be directly discharged, causing no environmental pollution compared to hydraulic or electric actuators.Pneumatic ball valves have been widely used in industries such as petroleum, chemical, power generation, papermaking, as well as in daily life.Supplier: Zigong ZIPU Valve & Pump Co., Ltd more>
