FAQS on sectional valve

Q: What is the primary function of a sectional valve in hydraulic systems?

A: A sectional valve modularly controls fluid flow and pressure in hydraulic systems. It allows customization by stacking multiple valve sections. This design simplifies maintenance and system adaptation.

Q: How does a Directional Control Valve differ from a sectional valve?

A: A Directional Control Valve specifically manages fluid flow direction in circuits. Sectional valves focus on modular pressure/flow control across multiple sections. Both are used in hydraulics but serve distinct operational roles.

Q: Why are tandem hydraulic pumps often paired with sectional valves?

A: Tandem pumps deliver combined flow rates for high-demand systems. Sectional valves efficiently distribute this flow to different actuators. The pairing ensures optimized pressure management and energy efficiency.

Q: Can sectional valves replace standard Directional Control Valves?

A: Sectional valves can perform directional control when configured with spool sections. However, standalone Directional Control Valves are typically more compact for simple systems. The choice depends on system complexity and scalability needs.

Q: What maintenance considerations apply to sectional valves in tandem pump systems?

A: Regularly inspect seal integrity between valve sections to prevent leaks. Monitor pump pressure to avoid overloading valve ratings. Cleanliness is critical to prevent particulate damage in both components.
