Heavy-Duty Multi Turn Wave Spring with High Corrosion Resistance and Custom Linear Characteristics for 35 MPa Cycle Durability in Hydraulic Cartridge Valves
Heavy-Duty Multi Turn Wave Spring
,Corrosion Resistance Multi Turn Wave Spring
Fluid power systems require fast, precise mechanical response times from internal check valves, cartridge valves, and fluid quick-connect couplings. Jiangsu Sanzhong Elastic Technology Co., Ltd. manufactures high-frequency Multi Turn Wave Spring elements designed to provide the swift spring-back force needed for high-pressure hydraulic components. Their compact axial profile allows fluid passages to be kept short, reducing fluid resistance and optimizing flow rates within valve blocks.
Our continuous-coiling manufacturing process eliminates any weld points or raw cut edges along the active turns of the spring. This flat surface prevents the spring from catching or binding on valve bores or guide rods during rapid compression cycles. Additionally, the uniform pitch of our crest-to-crest wave configurations ensures balanced fluid flow around the spring body, minimizing turbulence and cavitation in hydraulic lines.
- Hydraulic Cartridge Valves: Deployed as spool-return springs within manifold blocks for industrial machinery and material handling equipment.
- Fluid Quick-Disconnect Couplings: Positioned inside sliding locking sleeves to ensure quick, reliable connection engagement.
- High-Pressure Hydraulic Pumps: Used to maintain correct alignment of internal piston shoes against swashplates.
