INTRODUCTION
There are two types of MHPRG hand regulating valve MHPRG-A and MHPRG-B are ideal for metering or flashing expansion of liquid refrigerants. These valves are available in angle and globe types. These valves have stainless steel stems with back seating for seal replacementunder working conditions. MHPRG valve available in two variants- MHPRG-A for liquid expansion lines and MHPRG-B for liquid line flow regulation purpose. These valves are specifically designed as per international guidelines for refrigerating installations, specific flow conditions, and line characteristics. The MHPRG can also be used as a stop valve when the regulating function is not required. Interchangeable handwheel or seal cap available.Yellow seal caps or handwheels distinguish them from shut-off valves.
Note:- MHPRG regulating valves are upgraded design version of old MREG series. The dimensions and fitting connections for both valves are same. The MHPRG can be used as drop in replacement for MREG series. The pressure rating of MHPRG is 55 bar where as old MREG was 28 bar.
