Check valves are a critical component in many fluid systems and processes, only allowing gasses and liquids to flow in one direction and protecting your system from backflow. No matter the process or application, backflow can cause unplanned and unnecessary downtime, premature component failure, or even safety hazards, all of which cost your organization time and money.
Choosing the right valve is critical for performance and safety for any fluid system. Today, most fluid systems employ either poppet or ball-style check valves. While every fluid system has its own unique needs, selecting the correct check valve type will maximize performance and add value to your process. In many applications, upgrading to poppet check valves can offer superior reliability and performance compared to traditional ball valves.
Hy-Lok Canada is a proud manufacturer and distributor of check valves for a wide range of applications and industries, including oil & gas, petrochemical, airline and aerospace, and more. Read on to learn more about switching to Hy-Lok Canada’s poppet check valves, as well as our extensive inventory of valves and fittings for any application.
Why Switch to Poppet Check Valves?
In most applications, ball check valves have been considered the industry standard for many years. They feature a closing member shaped like a ball (hence their name). These balls are typically spring-loaded to maintain their seal and keep the valve shut. Some springless designs may rely on reverse fluid flow to create their seal and prevent backflow.
Because of their simple design, comparatively small size, and low manufacturing cost, ball check valves have long been seen as a cost-effective solution for most fluid systems. However, their performance in high-pressure applications is less than ideal; the roundness of the ball may allow for internal pressure discrepancies within the valve itself that can potentially lead to dangerous backflow. Especially in high-pressure applications involving fuel or other hazardous materials, an improper ball valve can lead to serious safety concerns for your equipment and workers.
Poppet check valves offer superior high-pressure performance through a more precise design. Instead of a ball, these valves feature a flat-bottomed poppet as the closing member, maintaining uniform fluid pressure within the component. Poppet check valves’ ability to maintain uniform, consistent pressure makes them a superior product in high-pressure applications, adding value through increased performance and fewer hazards.
