What is a Knife Gate Valve?
A knife gate valve is a linear motion valve designed to cut through thick media and provide a tight shut-off. It features a thin, sharp-edged gate that slides through the valve body to control flow.
Key Features:
- Heavy-Duty Design: Ideal for handling abrasive and high-viscosity fluids.
- Full Bore Flow: Ensures minimal pressure drop and unrestricted flow.
- Zero Leakage: Provides effective sealing with resilient seats.
- Corrosion Resistance: Built with high-grade materials to withstand harsh environments.
Av-Tek Valves offers knife gate valves built for reliability and durability, ensuring long-term performance.
How Does a Knife Gate Valve Work?
Knife gate valves operate by moving a flat gate into the flow path. When the valve is open, the gate is retracted, allowing flow. When closed, the gate moves down to block the flow completely.
Working Mechanism:
- Opening: The gate retracts, allowing fluid to pass through freely.
- Closing: The gate slides down to block flow and seal the passage.
- Sealing: Elastomer seats or metal-to-metal seals prevent leakage.
