Series Globe Style heck Valve thru INSTLLTION: Silent heck Valves, Wafer and Globe style must be installed between flat faced iron or steel flanges per NSI. or wwa 07, utilizing a full faced gasket to bridge the joint between the seat O.. () and the body () flange face. In this manner a pressure seal at this joint is made (see Note ). Install the valve so that the nameplate data is plainly read and the flow arrow points in the flow direction. MINTENNE: la-val Silent heck Valves are ruggedly designed for years of trouble-free service. Therefore, regular maintenance is not required. However, during initial start-up period the following problems may surface (due to mis-application) that can be easily resolved:. No Flow thru Valve:. Observe that the flow arrow name plate, on the valve body, is pointing in the direction of flow.. heck that the down stream shut-off valve is full open..
