Knife gate Valve
Overview
Knife gate valves, also known as knife gate valves, are designed for handling thick liquids, fibrous materials like pulp, or gases. They utilize a blade-shaped gate to control flow, which moves perpendicular to the flow direction. The gate's two sealing surfaces form a wedge when closed, ensuring effective shut-off.
- Structure: The valve body lacks a cavity; the gate moves in a side guide groove and presses against the valve seat for sealing.
- Sealing Options: Uses an O-shaped valve seat for bidirectional sealing; wedge gates can be rigid or elastic for improved sealing performance.
- Self-Sealing: Typically seals with medium pressure; external force may be required for forced sealing.
- Installation: Recommended for vertical pipeline installation.
Knife gate Valve Features
- Control Options: Can be operated locally or remotely with customizable position display and centralized control.
- Lightweight: Carbon steel body is 20%-30% lighter than traditional gate valves, facilitating easier installation and maintenance.
- Performance: Enhances pipeline closure and sealing, minimizing leakage and improving production efficiency.
- Material: Sealing surfaces made of highly wear-resistant and corrosion-resistant ceramic materials, extending valve life and enhancing cost-effectiveness.
