Knife Gate Valve

China Knife Gate Valve Manufacturer

The main function of the knife gate valve is to switch and isolate the liquid with high suspended solids content in the system. At the same time, the knife gate valve is particularly suitable for processing mud, viscous, corrosive, and abrasive media. When the knife gate valve is in the fully open position, the smallest pressure drop can be generated.

TIANYU Knife Gate Valve Manufacturer has been producing knife gate valve since 2009. DBV knife gate valve suppliers specialize in the production of customized knife gate valves. We can produce knife gate valves from 2″ to 96″ and above. tianyu knife edge gate valve manufacturer uses high-quality carbon steel, stainless steel and other alloy materials to produce valves.

Knife Gate Valve Advantages

  • Knife gates are cheap, easy to operate, and light in weight.
  • Knife gate valves have advantages in applications involving viscous fluids such as silt and mud because their blades can easily cut through thick liquids.
  • The corrosion resistance of the knife gate valve is very good.
  • The knife gate valve has a compact structure, a reasonable design, and less materials.
  • Knife gate valves have good sealing performance.
  • Our knife gate valve is very compact and easy for customers to operate.

Knife Gate Valve The "All-Rounder" Among Industrial Valves

Knife gate valves are indispensable in wastewater treatment, chemical processing, and metallurgy due to their anti-clogging, robust sealing, and wear resistance. Future advancements will focus on high-temperature/high-pressure performance, full electrification, and self-diagnostics. IoT-enabled smart valves already achieve 92% leakage prediction accuracy, enhancing system reliability. Selection should consider media properties (particulate size, corrosivity), operating parameters (pressure, temperature), and automation needs to optimize lifecycle costs.

The knife gate valve, as a key equipment for cutting off or connecting the medium in the industrial pipeline system, its design focuses on three core requirements: anti-ing, wear resistance and strong sealing, especially suitable for harsh working conditions containing particles, fibers, slurries and other complex media.

The Knife Gate Valve Core Competitiveness in Industrial Scenarios

1. Anti-Clogging Capability: Ideal for Complex Media
  • Knife edges cut fibers and particles, full-bore design reduces retention risks by >90%, suitable for slurries with >15% solids.
2. Enhanced Sealing: From Leakage Prevention to Zero Leakage
  • Soft seals meet API IV standards, hard seals achieve API VI (bubble-tight), critical for toxic media (e.g., cyanide solutions).
3. Dual Protection Against Corrosion and Wear
  • Diverse materials (cast iron/stainless steel/duplex) + treatments (lining/overlay) handle pH 0–14, chloride/sulfide environments; wear-resistant models last 3–5x longer in mineral slurries.
4. Ease of Operation and Maintenance
  • Low manual operating torque (80 N·m for DN200); electric/pneumatic actuators enable remote control; side-entry design allows online seal replacement, cutting maintenance time by 50%.
5. Multi-Functional ExpansionIntegrates sensors, limit switches for automation; some models offer throttling capabilities (e.g., V-port gates) for flow regulation.
