JMC SAPAG ® Butterfly Valve JMC BUTTERFLY VALVE FEATURES The maximum pressures and temperatures depend on the pressure / temperature ratio and type of fluid. Temperature,°C Resilient seated and bidirectional valve. Body type Double flange EN593 / API609 Cat.A / ISO10631 Centered top flange enabling direct actuator installation. This seal fitted on the flange enables you to protect shafting from the external environment. Bearings provide perfect shaft stability whatever pressure is exerted. • Fitted with a foolproof system that ensures correct butterfly assembly; • Dry shaft: no contact between...
