GENERAL
The V4 Actuated Wafer Type Butterfly Valves are suitable for heating and cooling applications. They can also be employed for industrial applications, general services and water treatment.
The V4 series is equipped with standard On/Off or modulating (4~20mA, 1~5V, or 0(2)~10V select by DIPswitch) control quarter-turn electric actuator.
FEATURES
· Cast Iron (V4) or SUS304 (V7) Wafer Body
· Centric butterfly valve with elastomer liner
· Wide DN-range (DN 50 … DN600)
· For On/Off or Modulating Control
· Robust actuators in epoxy coated aluminum
· Manual override non-clutch design. Manual operation can be operated without any lever, clutch or brake upon power voltage.
· Irreversible worm gear
· Visual mechanical position indicator for accurate visual reference of valve position
· Anti-condensation heater and 2 aux. limit switches on standard model
· Enclosure IP67
