Check Valve Spring Production & Design Solutions

Check valve springs are custom-engineered components developed by CATALOG for fluid control systems. We provide comprehensive design and manufacturing services to ensure reliable valve performance.

For our customer—a Nanjing‑based valve and fluid technology company—we addressed valve leakage caused by spring fatigue and permanent set (shortening) during operation. Through material reselection, redesign, and process optimization, we delivered springs that maintain consistent force and length over extended cycles, effectively resolving the leakage issue and meeting all operational specifications.

Pain Point Analysis and Solutions for Check Valve Springs

Challenge

Response

Outcome

Poor fatigue performance and spring shortening leading to valve leakage

1. Redesigned spring geometry for optimized stress distribution

2. Upgraded material selection for enhanced fatigue resistance

3. Implemented shot-peening process to improve durability and reduce plastic deformation

Achieved required fatigue life; eliminated permanent set and leakage; enabled successful transition to volume production

CATALOG Spring Solutions

Fatigue‑Optimized Structural Design

We redesign spring geometry to improve stress distribution and enhance mechanical performance under cyclic loading.

Process Enhancement with Shot Peening

Implementing shot‑peening increases surface compressive stress, significantly boosting fatigue resistance and preventing permanent deformation.

Precision Material Selection

Through iterative material evaluation, we select high‑performance alloys that meet stringent fatigue‑life and durability requirements.

CATALOG provides expert consulting services, technical insights, and professional solutions for various types of springs. Welcome to get in touch with us.
