Techno check valve is a type of check valve that is designed to prevent the reverse flow of fluids in a pipeline. It is an important piece of equipment in the oil and gas industry as it helps ensure safe and efficient operations.
A Brief History of Techno Check Valves
Techno Check Valves were first introduced by the Techno Corporation of Erie, Pennsylvania in 1952. Since then, they have been innovating and improving the design of their valves, including the invention of the elastomer hinge dual plate check valve which improved flow. Cameron, a leading provider of valves, valve automation, and measurement systems, acquired Techno Corporation in 2009. They continue to provide high-quality products to the oil and gas industry, controlling, directing and measuring the flow of oil and gas efficiently.
How Techno Check Valves Work
Techno Check Valves are essential components in the oil and gas industry. These multipurpose valves are engineered to control, direct, and measure the flow of oil and gas. But how do they work?
Techno Check Valves are designed to prevent backflow or reverse flow within pipeline systems. They feature specially designed flat, full-contact seals that maintain positive shutoff at low working pressures. These seals are replaced easily in the field, unlike most other valves. Torsion springs assist valve plate closure, preventing flow reversal.
When the pressure in the pipeline is greater than the Techno Check Valve’s cracking pressure, the valve will open allowing the fluid to flow through it. However, when the pressure drops below the cracking pressure, the valve will close preventing backflow or reverse flow. This is crucial because it keeps oil and gas moving forward towards refineries, petrochemical plants, and industrial centers.
