Swing check valves have become an indispensable choice in many industries due to their simple and effective design, while ensuring reliable performance and minimal maintenance requirements. Whether you are in water systems, oil and gas pipelines or industrial manufacturing, you cannot do without swing check valves. How to choose a suitable supplier among many swing check valve manufacturers has always been a headache. This blog will introduce you to several leading swing check valve manufacturers in the USA.
If you want to choose a suitable swing check valve manufacturer, you must first understand what a swing check valve is. Swing check valves are one-way valves that use a hinged valve disc. When the fluid flows forward, the valve disc opens, and when it flows in the reverse direction, the valve disc closes to prevent backflow. Therefore, a swing check valve can only allow the fluid to flow freely in one direction. This is the biggest feature of a swing check valve.

Q1: What is the difference between a swing check valve and a spring check valve?
A:Both swing check valves and spring check valves are check valves. The spring check valve relies mainly on spring force to assist the opening and closing of the valve disc. Due to the auxiliary effect of the spring, the sealing performance is better and due to the rapid closing of the spring, the water hammer phenomenon can be reduced. It is suitable for systems with large changes in fluid flow. The swing check valve relies on the hinged disc to open and close the disc by the fluid pressure difference to achieve fluid shut-off, and is suitable for situations where the fluid flows continuously.
Q2:Can swing check valves be used for air systems?
A:The swing check valve can be used in air systems, but in some air systems it can cause an air hammer effect when the pressure changes instantaneously, and it is easily affected by the air flow rate and cannot start or close properly.
Q3:What are common problems with swing check valves?
Water hammer: This can happen if the valve closes too quickly.
Air hammer: In air systems, air hammer can occur due to instantaneous pressure changes.
Wear: As swing check valves are used over time, the hinges or valve seats can wear and age.
Debris build-up: In some piping systems, debris in the medium can cause blockages that prevent normal operation.
Swing check valves are essential in ensuring one-way flow in pipelines and preventing backflow. Whether in municipal water supply systems, industrial pipelines, or petrochemical pipelines, choosing the right manufacturer greatly ensures the working performance of swing check valves.
