F643X Pneumatic Fan shaped Blind Plate ValveDetailed product description：

The F643X pneumatic fan-shaped blind valve automatic fan-shaped blind valve series is a new type of partition equipment that can be remotely operated and automatically controlled, based on the F43CX fan-shaped blind valve and improved and optimized according to its working characteristics.
This series of automatic fan-shaped blind plate valves has four driving modes: pneumatic, hydraulic, electric, and electro-hydraulic, and adopts different structural forms according to different specifications to meet the requirements of users' energy conditions, environmental conditions, and working conditions.
This series of automatic fan-shaped blind plate valves provides a safe and reliable isolation device for automatic control of toxic, harmful, and flammable gas pipelines in industries such as metallurgy, chemical engineering, and environmental protection due to their superior performance. The connection size of this valve complies with GB2555-81PN2.5 standard; The detection method complies with the GB/T13927-92 standard.

Product features and working principle:
F643X pneumatic fan-shaped blind valve, also known as pneumatic fan-shaped glasses valve, is mainly composed of left valve body, right valve body, screw rod, gate plate, sealing ring, lever, cylinder and other parts, and a rigid structure composed of base and support column. The valve is equipped with clamping and releasing cylinders, as well as a flap cylinder. The clamping and releasing cylinders are driven by levers and screw rods to loosen and clamp the left and right valve bodies, while the flap cylinder drives the gate plate to open and close. The rubber sealing ring is embedded with pliers on the gate plate, which has the characteristics of high temperature resistance, good sealing performance, easy replacement, and long service life.
This valve can be controlled remotely by a single unit or by multiple units connected to the network. In abnormal situations, it can also be manually operated using the valve's own device.
