Valve Springs

A valve spring is designed to return a valve to its closed position after it has been opened. They maintain the correct tension on the valve, ensuring smooth operation and preventing failure.

Materials Used

Choosing the right material for valve springs is vital because of the high pressures, temperatures, and continuous operation they face. We recommend:

Stainless Steel: Ideal for most industrial applications, this material offers exceptional corrosion resistance and durability.
Inconel: For environments requiring superior heat resistance, Inconel—a nickel-based alloy that performs well under corrosive conditions and at extremely high temperatures—is the preferred choice.

At European Springs, we manufacture valve springs in a range of materials to match the demands of different industries, ensuring long-lasting performance.

Applications in the Oil & Gas Industry

In the oil and gas sector, valve springs play a pivotal role in ensuring safe and controlled liquid flow. Their key functions include:

Flow Control and Pressure Regulation: Used in pipelines and refining systems, maintaining steady pressure and reducing leak risks.
Drilling and Wellhead Equipment: During drilling operations, these springs help absorb shocks and support the function of safety valves and hydraulic systems under heavy mechanical stress.
Emergency Shut-Off and Safety Valves: valve springs allow for the rapid closure of safety valves in urgent situations, thereby lowering the risk of blowouts and environmental harm.

Broader Applications

Valve springs are critical in various industries beyond oil and gas, such as:

Automotive: Valve springs in V8 engines control the intake and exhaust valves, optimising air and fuel flow for better performance and reduced emissions.
Aerospace: In aircraft like the Boeing 737, springs regulate fuel flow to engines and manage hydraulic pressure for flight control surfaces.
Medical Devices: In infusion pumps, valve springs ensure accurate fluid delivery for medications, while in respirators, they regulate airflow to maintain proper ventilation.
