Check valve is a type of valve used to protect the system of hydraulic circuit piping, liquid pipes, pumps, tanks, against leakage of liquid, gas or vapor. With the function of only allowing fluid to pass through the valve in one direction (one direction) and preventing the opposite direction. Check valve is the English name of the valve.
Counter-counter check valve is also known as hydraulic weight check valve. Being hydraulically controlled, these valves are usually large in size. Counter-counter check valves are designed to be fitted to the outlet of a piping system, hydraulically controlled, behind a pump system. Counter-counter check valve is responsible for protecting the piping systems, preventing fluid reflux, causing pressure imbalance leading to system damage.

Design of counterbalance check valve
Principle of operation
Counter-counter check valves work similarly to normal check valves, however the valve has a 90 degree opening angle, when completely closed the valve will lie at an angle of 30 degrees compared to the vertical direction of the valve. valve. When there is a flow of fluid through the pressure, the valve will open, creating an angle of 90 degrees from the limiting position of the valve. When we stop flow, the valve will close at an angle of 60 degrees very quickly and slowly close from an angle of 30 degrees to the closed state. The operating mechanism of the counter-counter valve helps the valve to maximize the flow of fluid through and the wing closes slowly to prevent the valve wing (valve disc) from being impacted strongly, limiting valve damage.
Application
Counterbalance check valves are widely used in many hydraulic equipment in ventilation, fire fighting, water, heat, steam or air engineering systems and waste treatment.
