Hydraulic Hose Fittings Three valves used correctly

Three valve is composed of three consisting of three valves communicate with each other. Each valve in the

system according to the role can be divided into: the left side of the high pressure valve, parher reusable hydraulic hose fittings the right for

the low-pressure valve, balance valve middle. The difference between the three valve Transmitter, a positive

effect, negative pressure measuring chamber and the lead point on or off; positive or negative pressure

measuring chamber is disconnected or turned on.
The main role: It is in the installation and removal of the need to use balancing valve Otherwise,

differential pressure range is generally small, if the manufacturers of overload is not strong, it is easy

to damage.
Here is a simple example: If the differential pressure is 60KPa, pipeline pressure 1MPa time, if there is no

balance valve, parher metric hydraulic hose fittings both first take positive or negative pressure chamber room, both sides would immediately lead

to a differential pressure far parher hydraulic couplers exceeds the set value because the first take that party will have a direct

and open to the atmosphere, the equivalent of 0.1MPa, this operation is fatal.
