SAPAG-0010-ENG-2301 The maximum pressures and temperatures depend on the pressure/ temperature ratio and the nature of the fluid. Temperature,°C -196 °C (*) Standard vacuum resistance: 1 torr DISCOVANNE HIGH PERFORMANCE DOUBLE OFFSET BUTTERFLY VALVE GACHOT® Double offset and, according to the design, Bidirectional. The eccentricity of the shaft, and of the disc with the seat have the following benefits: • Low operating torque, • Reduced seat wear, • Lack of retention zone. Can be used in isolation and setup service. Design Standard Shaft control The groove assembly allows the distribution of the operating torque on the shaft. Cable gland Series of compact graphite rings with high temperature resistance, or PTFE, according to the design. Easily accessible packing gland thanks to a bracket system. Use of self-lubricating rings with low coefficients of friction and large spans ensuring longevity and robustness. Precise positioning of the disc thanks to centering rings. Metal seat with metal O-ring to reduce valve torque. Built-in stop to limit any over-opening. Design of studied profile assuring high flow rates and low flow rates pressure losses. In metal gasket version, treatment increasing surface hardness of the disc. The valve is a spherical segment whose circumference in contact with the seat ensures perfect sealing.
