Question 1

What are logic valves hydraulic?

Accepted Answer

Logic valves hydraulic are cartridge-type hydraulic valves used inside manifolds to control direction, pressure, or flow through pilot pressure and internal force balance.

Question 2

How do logic valves hydraulic work?

Accepted Answer

Logic valves hydraulic work by comparing pressure forces acting on different valve areas. When the required pressure condition is reached, the valve opens, closes, or blocks flow.

Question 3

What is the role of pilot pressure in a logic valve?

Accepted Answer

Pilot pressure controls whether the valve opens or closes. A small pilot signal can control a much larger main flow inside the hydraulic circuit.

Question 4

Can a logic valve work as a check valve?

Accepted Answer

Yes. A logic valve can be configured to allow flow in one direction and block reverse flow, making it useful for load holding and anti-drift functions.

Question 5

What information is needed for replacement selection?

Accepted Answer

Common information includes original model, cavity size, pressure, flow rate, pilot control type, seal material, hydraulic function, and application details.
