ISO Square Drive for sizes 50-300mm and positive keyed drive for sizes 350mm and above. Actuator mounting flange, conforms to ISO5211 and accommodates all types of operators, lever, gear, electric, hydraulic and pneumatic Four self lubricating bronze bushes provide maximum stem support with minimum friction. Eliminates potential stem seizure. O ring weather seal prevents ingress of moisture and external material into the stem area. Pressure surge seals (O rings) are moulded inside the seat stem hole area to provide failsafe sealing around stem, eliminating possible leakage. One piece thru-stem design ensures dependability and positive disc control. Phenolic resin backed seat provides support for the seat is non-collapsible, stretch resistant, blowout proof and suitable for vacuum. Internal square drive and precision taper pins ensure positive, vibration proof, stem to disc connection. Square drive 300mm size Pins 350mm size Precision profile disc provides bubble-tight shutoff with minimal disc/seat interference, assuring minimum torque and longer seat life. Polished disc flats mate with seat flats to give a highly efficient seal; prevents leakage into stem area. Universal flange adaptability for wafer style in size range. Suits ANSI 125, DN16, AS 2129 Table D & E. Supported stem seal protects against distortion, a common cause of stem leakage.
