Miniature check valve

Introduction to Miniature Check Valve

Micro check valve is a miniaturized check valve, mainly used to control the one-way flow of fluid (gas or liquid), to prevent backflow. Its core feature is small size, light weight, suitable for space-limited occasions. 

The micro check valve is usually composed of a body, a spool and a spring. When the fluid is flowing forward, the pressure pushes away the spool; In reverse flow, the spring presses the spool back, preventing the fluid from passing through.

Micro-check valve has a wide range of applications in many fields, the selection of the need to consider flow, pressure, media and temperature and other factors.

DELTA unidirectional throttle valve is an embedded micro component with a filter screen. When the liquid flows through the throttle hole, a pressure difference is generated between the front and rear ends of the sealing ball, causing the sealing ball to completely detach from the sealing seat. This unique design eliminates the clogging problem that occurs when the throttle valve and the one-way valve are used in series.

DELTA one-way throttle valve is suitable for scenarios where one direction allows flow while the other direction is blocked. For example, when there is flow during operation, the valve should prevent the fluid from flowing downstream when it is closed.

We can manufacture substitutes for Lee valves, is Leading Micro Valve Manufacturer. Several dozen types of Alternative to Lee Check Valve have been developed, and there is a corresponding model list, please contact us for requesting the list. Those who need them can directly place orders for the corresponding models.

Other types of miniature components can also be jointly developed. Several key factors need to be considered for miniature check valve production: 1. The clearly defined demand model, with a continuous demand quantity and an annual demand of more than 100 pieces. 2. Your company has several samples, even old ones, or individual sections are fine. 3. For the first purchase, we are willing to pay the sample fee (ranging from several thousand dollars). We will provide 5 to 10 samples. 4. Your company has the ability to conduct performance tests and verification of your products, and provide performance test reports to Delta Precision for feedback. 5. There are technicians willing to assist Delta Precision in the joint development.
