Component Specifications

Definition
A precision mechanical spring designed specifically for poppet or seal assemblies in industrial equipment, typically providing consistent compressive or extension force to maintain proper sealing contact, control valve actuation timing, or ensure return-to-position functionality in pneumatic, hydraulic, or mechanical systems.
Working Principle
Utilizes elastic deformation properties to store mechanical energy when compressed or extended, then releases this energy to exert controlled force against poppet/seal elements, maintaining consistent sealing pressure or enabling precise actuation movements through Hooke's Law behavior (F = kx) where force is proportional to displacement.
Materials
Typically made from spring steel (ASTM A228/A229), stainless steel (302/316), Inconel for high-temperature applications, or beryllium copper for non-sparking environments; may include corrosion-resistant coatings like zinc plating or powder coating.
Technical Parameters
  • Free Length 10-100 mm
  • Spring Rate 5-50 N/mm
  • Solid Height 5-80 mm
  • Wire Diameter 0.5-5.0 mm
  • Maximum Deflection 60-80% of free length
  • Operating Temperature -40°C to 250°C
  • Load at Working Height 10-500 N
Standards
ISO 10243, DIN 2095, ASTM A125

Frequently Asked Questions

What is the primary function of a spring in poppet/seal assemblies?

The spring maintains consistent sealing force against the poppet or seal element, ensuring leak-proof operation while allowing controlled movement during actuation cycles.

How do I select the correct spring for my application?

Consider operating pressure, temperature range, required spring rate, corrosion environment, cycle life requirements, and compatibility with fluid media, then match to specifications like ISO 10243.

What causes spring failure in these applications?

Common causes include fatigue from cyclic loading, corrosion from harsh environments, over-compression beyond design limits, and material degradation at extreme temperatures.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
