The company says the latest model features key safety advancements including an automatic change over valve for an emergency air supply cylinder, available in different durations, and a locking hand wheel on the cylinder pressure
reducing valve to prevent inadvertent shut-off during use.
At present, for the CNC heavy machine-tools manufactured in Romania, the following associations of functions can be obtained: 1, 2 and 5 to (80-100 bar); 2, 3 and 5 to (30-40) bar; 4 singular at (15-60) bar, depending on the applied solution; 6 singular at (80-110) bar with pump with pressure regulator; 7 singular at 100 bar with proportional
reducing valve; 8 singular, possible with drain lubrication, with pressure adjustment or constant flow.
This AD requires identification of the part and serial numbers of the pressure
reducing valve on each air pressurisation unit, testing pressure
reducing valves and air pressurisation units having affected serial numbers, and replacing faulty valves or units with new parts.
Industrial valves featured in product bulletins include the Model V control valve for use in areas where precise pressure and temperature control are needed, the RV pressure
reducing valve, and the Adjustable Orifice valve, a three-position shut-off valve used in areas such as cold water circulation.
The electro-pneumatic pressure
reducing valve adds a convenient control function to a range that already combines a pressure
reducing valve, separator and steam trap in one compact unit.
However, we realised that in order to increase the productivity of the process we needed to increase the efficiency of the heat transfer, and TLV suggested fitting its new CV-COS electro-pneumatic pressure
reducing valve, which combines a convenient control function with a pressure
reducing valve, separator and steam trap in one compact unit."
The basic element of the balancing is the
reducing valve with three ways (Prodan, 2004).
This AD would require identification of the part and serial numbers of the pressure
reducing valve on each air pressurisation unit; the testing of pressure
reducing valves and air pressurisation units with affected serials numbers, and the replacement of faulty valves or units with new parts.
The RV Series pressure
reducing valve has been introduced by the company.
