Overview of Z45X Soft Sealed Concealed Rod Gate Valve Product DiagramThe Z45X soft sealed concealed stem gate valve is a valve that opens or closes fluids by vertically lifting and lowering the gate (valve plate). The stem of the concealed stem soft sealed gate valve only rotates during valve opening and closing, and does not move up or down. Its threaded part is located inside the valve body and is connected to the gate nut. We usually only see the handwheel rotating and cannot see the valve stem lifting or lowering.
