DELCO PZ643XH Pneumatic Plum Blossom Knife Gate Valve - V-Notch Flow Control
The DELCO PZ643XH features a specialized Plum Blossom (V-Notch) gate design, transforming the standard knife gate valve into a precise control device. Unlike standard on/off valves, this unique geometry provides accurate flow regulation while maintaining the ability to shear through fibers and slurries. It is widely used for throttling pulp, coal slurry, and wastewater.
Features
A specialized pneumatic knife gate valve with a V-notch plum blossom gate, offering both fiber-shearing capability and precise flow regulation for slurry systems.
✅V-Notch Control Characteristic: The Plum Blossom (V-shape) gate opening creates a precise flow characteristic, allowing for linear regulation of fluid volume, making it superior to standard Pneumatic Knife Gate Valves for throttling duties.
✅Shearing & Throttling: Combines the cutting power of a knife gate with the control of a regulating valve, effectively shearing through suspended solids while adjusting flow rates without clogging.
✅Anti-Clogging Design: The V-port design prevents solid particles from accumulating at the gate bottom, ensuring continuous smooth operation even in high-concentration slurry lines.
✅Wear-Resistant Construction: The gate and seat are often hardened or surfaced with Stellite to resist the erosive effects of high-velocity abrasive fluids passing through the throttled opening.
✅Integrated Automation: Powered by a pneumatic actuator with a [Valve Positioner], it accepts 4-20mA signals to automatically adjust the gate position for precise process control.
