Stainless steel discs and EPDM rubber sheets are available for various types of line-fluids without concern for corrosion. A pair of stem bearings assembled around the upper and lower stems prevents stem galling, stabilizes valve operating torque, and ensures smooth and trouble-free disk rotation. The actuator mounting pads on the neck are designed to allow direct field mounting of actuators with ISO5211 mounting flanges. No insulation is required to block the heat of the fluid from being transferred to the valve operating device along the neck of the stainless steel. Condensation is minimized ev
