Product Description

 

Product Description

Introduction:

The knife gate valve boasts advantages such as simple and compact structure, rational design, lightweight material-saving construction, reliable sealing, easy and flexible operation, small size, smooth flow path, low flow resistance, light weight, simple installation, and convenient disassembly. It effectively addresses common issues found in conventional gate valves, slab gate valves, globe valves, control valves, butterfly valves, and ball valves, including excessive weight, high flow resistance, large footprint, and difficult installation. This valve can serve as a replacement for general-purpose shut-off valves and control valves, operating reliably under working pressures of 1.0MPa-2.5MPa and temperatures ranging from -29°C to 550°C.

Structural Advantages:
Lug-Type Design:

• The valve body features symmetrical lugs on both sides, allowing direct bolting to pipeline flanges without additional flanges, saving installation space and costs.

• Supports single-side disassembly, enabling valve maintenance or replacement without disrupting the entire pipeline system.

• Compact and lightweight:

  • Simpler structure and lighter weight compared to traditional gate valves, ideal for space-constrained applications.

Sealing Performance

• Bidirectional sealing:

  • Utilizes elastic seats or metal + soft sealing combinations to ensure tight shutoff in both flow directions (inlet/outlet).

• Resistance to particulate wear:

  • The wedge-shaped knife gate cuts through fibrous, granular, or viscous media (e.g., sludge, slurries), preventing clogging.
