Buy Blind Plate Valve F43X PN10/PN16 Cast Iron Flanged Manual Operated
The F43X Manual Blind Plate Valve from VALVEHU is a reliable and cost-effective solution for industrial applications requiring isolation or shutoff of flow. This manually operated valve features a dual-body design with a rotatable blind plate that ensures a tight seal when engaged. The valve is engineered with simplicity and ease of maintenance in mind, offering robust performance in general-purpose pipelines.
Designed for low to medium pressure systems, the F43X blind valve is typically installed between two pipeline flanges and manually tightened or released using a screw mechanism. Its operation relies on shifting the blind disc between the flow path and the vent hole, enabling clear open/close positioning. This makes it ideal for use in systems where infrequent operation and high reliability are priorities.
The valve’s compact short-structure design, along with its lightweight body and simple mechanical configuration, offers benefits such as reduced installation footprint and ease of handling. The rubber seal rings are positioned on both sides of the valve body to provide enhanced sealing performance and minimize leakage risk.
Commonly used in dust control, power plants, metallurgy, and chemical industries, this type of knife gate-style valve provides excellent flow isolation in solid, slurry, or low-pressure fluid applications. With flange-end connection, manual actuation, and availability in cast iron or carbon steel bodies, it suits a variety of pipeline configurations.
Whether you’re managing a new pipeline project or replacing outdated shutoff systems, the F43X model blind valve delivers durability and operational safety.
