Floating ball automatic exhaust valve: uses the buoyancy of the floating ball in water to control the opening and closing of the valve. When there is gas accumulation in the system, the float descends, the valve opens, and the gas is discharged; After the gas is exhausted, water enters the valve, the float rises, and the valve closes.

Leverage type automatic exhaust valve: The opening and closing of the valve is controlled by the lever principle. When gas accumulates in the system, the pressure of the gas causes the lever to lose balance, thereby opening the valve and releasing the gas.
Spring type automatic exhaust valve: uses the elastic force of the spring to control the opening and closing of the valve. When gas accumulates in the system, the pressure of the gas overcomes the elastic force of the spring, causing the valve to open and release the gas.
Manual exhaust valve: such as ball valve manual exhaust valve and gate valve manual exhaust valve, which control the opening and closing of the valve by rotating the ball valve or lifting the gate.
