Types DBT and DBWT remote control pressure valves are pilot operated pressure relief valves.
Type DBT consist mainly of the main valve (1), main spool (2), valve seat (3), and adjustment (6)
The pressure of system acts on the spool(2) via orifice. If the pressure exceeds the valve set at the spring, the pressure fluid drain to tank from port T(or drain external).
Structure and symbols of pressure relief valve DBT
1.The fluid must be filtered. Minimum filter fineness is 20 ㎛.
2.The tank must be sealing up and an air filter must be installed on air entrance.
3.Products without subplate when leaving factory.
4.Valve fixing screws must be high intensity level (class 10.9). Please select and use,them according to the parameter listed in the sample book.
5. Roughness of surface linked with the valve is required surface roughness is 0.8.
6. Surface finish of mating piece is required to 0.01/100mm.
