Check Valve
A check valve is an automatic, one-way valve that allows fluid (liquid or gas) to flow in one direction only. Also known as a non-return valve, it automatically closes to prevent reverse flow, which can cause contamination, equipment damage, and system inefficiency.
Functional Features
-
One-Way Flow
The primary feature is to allow fluid to pass in only one direction, preventing backflow.
-
Automatic Operation
Check valves are self-operating and do not require handles or external controls; they open and close automatically based on the fluid's flow pressure and velocity.
-
Two Ports
They have two openings: an inlet port for fluid to enter and an outlet port for it to exit.
-
Backflow Prevention
This function protects pumps and other equipment by ensuring flow in the desired direction only.
-
Mechanical Robustness
They are designed to withstand the stresses and vibrations found in plumbing and pipeline systems.
