A two-way cartridge valve for aggressive media has a replaceable module including a main valve seat, a diaphragm sealing member for the valve seat, and a pilot seat. In one embodiment, a leaf spring is employed to bias the diaphragm toward the open position for actuation under conditions of minimal pressure differential. In another embodiment a resilient support is provided for the diaphragm behind the region of engagement with the main seat. |
