DIGITAL DISPLAY DOUBLE TABLE VALVE

SBF-L-07

Function Introduction


◆Widely used in the area of hydraulic and atmospheric pressure as refrigerant equipment, air conditioner and refrigerant tools , pressure tools, vacuum equioment, pneumatic equipment,etc.
◆This gauge has no moving parts, has long service life, high precision, good long-term stability.
◆It has pressure and temperature parameters for commonly used refrigerant inside,the measured pressure, condensation temperature and evaporation 
temperature etc is very clear to see. 


Applied range

◆ The SBF-L-07 digital display double table valve is used for the assembly and maintenance of vacuum refrigeration system. The operator must possess the qualification of the industry and have certain operational experience. 
◆ The SBF-L-07 digital display double table valve sets together with the traditional composite table, the temperature measuring instrument and the refrigerant characteristic diagram, and it’s available to measure both pressure and temperature. 
◆ The SBF-L-07 digital display double table valves are suitable for most non-corrosive refrigerant, water, alcohols. But it is not suitable for the refrigerant containing ammonia.
◆ This product is not suitable for the areas with explosion - proof requirements.
