Pneumatic Through-Type Knife Gate Valve
Pneumatically actuated through-type knife gate with self-cleaning seal design, ideal for media containing particles, fibers, or slurries.
Inquire NowProduct Overview
The through-type knife gate valve features a sharp beveled gate that cuts through thick media, passing completely through the valve body when fully open — leaving a full-bore, unobstructed flow path. The pneumatic actuator provides quick, reliable on-off operation for the toughest slurry and solids-handling applications.
Self-cleaning seal design scrapes the gate clean on every stroke, preventing media buildup and ensuring long-term reliable sealing even with sticky or fibrous materials.
Key Features
- Full Bore Flow: Gate retracts fully from the flow path when open — zero obstruction, zero turbulence
- Self-Cleaning Seal: Wiping action of the gate against the seal clears debris on every stroke
- Sharp Knife Edge: Cuts through settled solids, fibers, and thick slurries
- Bi-Directional: Seals in both flow directions under full differential pressure
- Low Profile: Face-to-face dimension much shorter than conventional gate valves
Technical Highlights
Typical Applications
Wastewater sludge lines, paper pulp & stock handling, mining tailings, biomass processing, chemical slurry systems, food processing waste, dredging pipeline isolation.
产品概述
穿透式刀闸阀采用锋利斜切刀板穿透浓稠介质，全开时刀板完全退出流道——实现全通径无阻碍流通。气动执行器为最严苛的浆料和固体处理工况提供快速可靠的开关操作。
自清洁密封设计在每次行程中刮擦刀板，防止介质堆积，即使面对粘性或纤维状物料也能确保长期可靠密封。
核心特点
- 全通径流通：开启时闸板完全退出流道——零阻碍、零湍流
- 自清洁密封：闸板每次行程对密封面的刮擦作用清除残渣
- 锋利刀刃：可切断沉积固体、纤维和浓稠浆料
- 双向密封：在全压差下实现双向密封
- 超短结构：面到面尺寸远小于传统闸阀
