Winner spring-return zone valve SW-BBSP series have compact structure, stable operation, excellent capacity of water stoppage, large water flow rate, zero dirt block and low torque. Winner spring-return zone valves are widely used in fan coil units, cooling/ heating system and HVAC system.
Application
Fan coil units, cooling/ heating system and HVAC system.
Operational mode
Winner spring-return zone valve is motor-operated by on/off type actuator. The actuator adopts totally
closed unidirectional hysteresis synchronous motor, having waterproof design and spring automatic reset
