manual knife gate valve
A manual knife gate valve is a specialized flow control device designed for precise shutoff applications in various industrial processes. This robust valve features a flat blade or gate that moves perpendicular to the flow, providing exceptional sealing capabilities and reliable performance. The manual operation mechanism typically consists of a handwheel that, when turned, raises or lowers the gate through a threaded stem assembly. The valve's design incorporates metal-to-metal seating, making it particularly effective in handling viscous fluids, slurries, and materials containing solid particles. Its straightforward construction includes a valve body, gate, stem, packing system, and manual actuator, all working together to ensure efficient flow control. The valve's ability to provide bidirectional sealing and its self-cleaning design during operation make it an ideal choice for challenging applications. With its compact face-to-face dimension and full port design, the manual knife gate valve offers minimal pressure drop and maximum flow capacity when fully open.
