Common features for Series Q146 and Q147
The valves are equipped with a stainless steel ball check to shut off flow automatically in case of glass breakage. The bonnet is part of the valve body in the form of a thread. A union vessel connection makes it easy to install valves on to the vessel and allows ¼” inch variation in vessel centres. Union connection could be ½” or ¾” NPT spherical ½”, or flanged. These valves have offset pattern bodies which mean that gauge connection and drain are off center by 7/8” for the center line of the vessel connection. Due to the offset pattern, the gauge could be cleaned by removing the drain plug from the valve without disassembling the gauge. The material is dropped forged steel bodies that conform to ASTM requirements, the handwheel is malleable iron.
