Wafer type butterfly valve

wafer type butterfly valve

FEATURES

• Bi-directional zero leakage butterfly valve
• ISO pad for mounting, Hand Lever/ Gear operator/Actuator
• Stem design as per DIN 475 to mount actuator, Gear Operator, Hand Lever
• Extremely small play between the stem and disc due to square drive
• Accurated dual stem sealing prevents leakage
• A safety arrangement prevents the stem from lifting during maintainence or working with an actuator
• The burnished stem is supported in multiple high techno polymer bearings. This prevents deflection under high pressure. Provides smooth operation and long life.
• Easily serviceable at customer end
• Butterfly valve can be mounted between flanges as per EN 1092, ASME/ANSI,JIS,BS-10.
• 100% factory tested under Water/Air/Vacuum before the valve is packed and shipped.
• Downstream connection: Rotex Butterfly Valve Series TITLI can be used for Downstream connection, held with Hexagonal Nut (DIN 934). The Butterfly valve can also be used for end of line connection with or without a blind flange
• TOTAL SOLUTION! COMPLETE VALVE AUTOMATION SYSTEM FROM ROTEX. INCLUDES ROTEX PNEUMATIC ROTARY ACTUATOR, LIMIT SWITCH, NAMUR SOLENOID VALVE, HAND LEVER, MANUAL GEAR OPERATOR, POSITIONER, AIR FILTER, REGULATOR, LUBRICATOR
