Pneumatic check valve straight fitting

A stainless steel push-in fitting check valve is a type of valve that allows fluid to flow in only one direction. It is made of stainless steel, which provides durability and resistance to corrosion. The push-in fitting design allows for easy installation and removal without the need for additional tools or fittings. The check valve works by using a spring-loaded disc or ball that opens and closes based on the direction of fluid flow. When the fluid flows in the desired direction, the valve opens, allowing the fluid to pass through. However, if the fluid tries to flow in the opposite direction, the valve closes, preventing backflow.
