G41J Rubber-line Diaphragm Valve

G41J-10 Rubber lined diaphragm valve is a type of diaphragm valve that is only operated by applying torque on the handwheel. G41J-10 Rubber lined diaphragm valve operates when the diaphragm valve operator applies a torque on the handwheel to either start or stop fluid flow. The start of fluid flow through a manual diaphragm valve starts when the handwheel is rotated in the clockwise direction forcing the stem and compressor to move upwards. This then forces the diaphragm to move upwards and this leaves the diaphragm valve open for fluid to flow. To stop G41J-10 Rubber lined diaphragm valve, the handwheel is then rotated in the anticlockwise direction forcing the diaphragm to create a tight seal with the body and thus blocking any fluid flow.  二.Product Features
