Springs in directional control valves are mechanical components that provide return force to reset valve spools or poppets to their neutral position after actuation.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Free Length | 20-100 mm | |
| Spring Rate | 10-200 N/mm | |
| Fatigue Life | >1 million cycles | |
| Solid Height | 10-50 mm | |
| Coil Diameter | 10-30 mm | |
| Wire Diameter | 1-5 mm | |
| Pre Load Force | 5-50 N | |
| Operating Temperature | -40°C to 120°C |

This component is used in the following industrial products
A hydraulic valve that controls the direction of fluid flow in a hydraulic system.
A brake master cylinder is a critical component in hydraulic braking systems. It converts mechanical force from the brake pedal into hydraulic pressure, which is then distributed to the wheel cylinders or calipers to apply braking force.
A mechanical system within a tool clamping assembly that secures the tool holder or cutting tool in place during machining operations.

Spring failure can cause the valve to stick in an actuated position, leading to unintended machine movement, loss of control, or system pressure issues, potentially resulting in equipment damage or safety hazards.
Consider spring rate, pre-load force, fatigue life, material compatibility with fluid/environment, and compliance with standards like ISO 10243. Match OEM specifications or consult valve manufacturer guidelines.
Yes, but replacement must match original specs precisely. Use identical spring rate, dimensions, and material to ensure proper valve function and avoid warranty or safety issues.
