Pressure switch DNB-250K-22B DNB-150K-22B

Pressure switch DNB-250K-22B DNB-150K-22B
Product name : Pressure switch DNB-250K-22B DNB-150K-22B
Item :
Details :
 Pressure switch DNB-250K-22B DNB-150K-22B


Regulating method of hydraulic pressure switch:
 
The hydraulic pressure switch DNB-070K-22B is a circuit switch controlled by an electrical signal. When the discharge pressure of the compressor is greater than the set value or the suction pressure is lower than the set value, the pressure switch DNB-150K-22B will cut off the circuit to protect the safety of the hydraulic system and equipment. In small hydraulic system, high and low pressure switch DNB-040K-22B is generally used, dnb-250k-22b pressure relay is commonly used. The pressure switch is composed of electric contact, high and low pressure bellows, lever mechanism, balance spring and amplitude difference adjusting mechanism. When the pressure changes, the bellows will produce expansion deformation movement, pushing the electric contact to cut off or connect the circuit.
