Product Description

Description 
Winner 4N.m WAV4-… series motorized actuated control ball valve consists of WVA4-1../-2../-3.. rotary actuator and WSBV… series stainless steel ball valve. 
  • The actuator is controlled by a modulating on/off , 3-point or proportional control system and move the ball of the valve. 
  • It has manual and indication functions.
 
Application
HVAC system, heating system, water treatment equipment, and water running control in industrial automation, such as: AHU, flesh air-handling unit, differential pressure control unit and heat exchanger for flow regulation and on/off control.
