Balance valve consists of one-way valve and sequence valve, balance valve can be divided into three types: static balance valve, dynamic balance valve and pressure difference independent balance valve. Balance valve is generally used in the variable load mechanism of the cylinder oil port (generally large cavity) in front. Equivalent to liquid control one-way valve composition. If the large cavity oil, through the one-way valve normal oil intake; If the small cavity feed oil large cavity back oil, first small cavity pressure to act on the balance valve above the one-way valve open, large cavity can return oil. The opening condition is that the oil inlet pressure of the small chamber is higher than that of the large chamber by a certain value (set value).
 
It does two things:
 
1. Prevent the cylinder from dropping due to the sudden loss of pressure in the large cavity inlet oil path;
 
2. Prevent the danger of excessive oil return speed caused by load inertia.
 
Balance valves are also commonly used in hydraulic motors.
 
The balance valve is in the hydraulic condition, plays the dynamic, the static balance adjustment valve. Balance valve can be divided into three types: static balance valve, dynamic balance valve and pressure difference independent balance valve. Static balance valve is also known as the balance valve, manual balance valve, digital locking balance valve, two-position control valve, etc., it is through changing the gap between the valve core and the seat (opening), adjust the valve Kv (valve flow capacity) to change the flow resistance through the valve to achieve the purpose of regulating flow.
 
The principle of the balance valve is the reverse adjustment in the body, when the inlet pressure increases, automatically reduce the size, reduce the flow of change, and vice versa. The regulating system won't work if it's connected backwards. And the valve plate, which plays a regulating role, is directional, reverse pressure can even reduce or even close the flow.
 
Since the balance valve is installed for better heating, there is no backloading problem. If it is reverse loading, it is a human error, and of course it will be corrected. Balance valve belongs to the category of regulating valve, its working principle is through changing the gap between the valve core and the valve seat (that is, the opening), change the flow resistance of fluid flow through the valve, to achieve the purpose of regulating flow.
