It’s entirely possible to install two knife gate valves in series with a flange-to-flange connection using longer bolts, but there are some considerations to ensure smooth operation and longevity. With V-TORK knife gate valves, you can trust that their precision engineering and robust design will help you achieve a reliable and efficient setup.

Key Considerations with V-TORK Knife Gate Valves:

1. Alignment and Bolt Stress
2. Valve Performance
3. Maintenance Accessibility
4. Pressure and Flow Characteristics
5. Actuator Operation

Now lets deep dive into each considerations for installing two knife gate valves in series.

1. Alignment and Bolt Stress

• Proper alignment is critical to avoid stress on bolts and valve bodies. V-TORK valves are designed with accurate dimensions and a compact profile, making alignment simpler and more secure.
• Using longer bolts? Ensure you select high-grade materials to handle the stress. V-TORK valves are compatible with custom flange configurations for such scenarios.

2. Valve Performance

• V-TORK U-Series (Uni-Directional) or B-Series (Bi-Directional) knife gate valves are built to handle heavy-duty applications with slurry, pulp, or corrosive fluids. Their advanced seat designs ensure a tight shut-off, even with minimal spacing.
• Slight rotation of the valves to avoid actuator collision is a good move, and V-TORK actuators are designed for optimal placement and ease of access.

3. Maintenance Accessibility

• Placing two valves in series could make maintenance tricky, but V-TORK valves are engineered for minimal wear and easy serviceability. Ensure there’s enough room to disconnect each valve individually.

4. Pressure and Flow Characteristics

• V-TORK valves are tested for high-performance applications and are known to handle pressure drops and flow turbulence efficiently. This ensures minimal disruption to system performance.

5. Actuator Operation

• The compact and ergonomic actuator designs of V-TORK valves ensure smooth operation without interference, even in tight spaces.
