RDHB-CJ-51 Flow Control Stop Valve
• Working pressure : 6-16 MPa;
• Maximum traffic : 3.7 L/min;
• Applicable liquid : HM15、HM32、MH46;
• Installation method : superimposed installation, (usually installed in the solenoid valve box);
• Function : P port throttling function;
• Function description : This valve is superimposed on the valve strip in the solenoid valve box, which can adjust the flow of port P and can also cut off the hydraulic pipeline of port P;
• Installation environment : dry, non-open-air, non-corrosive environment;

RDHB-CST-51 Combined Two-way Safety Hydraulic Control Lock
• Working pressure : 6-20MPa;
• Applicable liquid : HM15、HM32、MH46;
• Applicable temperature : -20℃~60℃;
• Overflow pressure range : 13 MPa~25 MPa;
• Installation : Superposition installation (usually in solenoid valve box);
• Functions : hydraulic lock, high temperature overflow;
• Function Description : This valve is superimposed on the valve bar in the solenoid valve box, which can replace the function of hydraulic lock, and has the function of high temperature overflow at the same time, so as to prevent the pressure in the pipe from being too high due to the increase of ambient temperature, and the system pressure can not switch the valve normally;
• Installation environment : dry, non-open, non-corrosive environment;
