Model: SW-B202H
Description:
Winner spring-return zone valve SW-B...H BSP series have compact structure,stable operation,excellent capacity of water stoppage, large water flow rate, less dirt block and low torque. Winner spring-return zone valves are widely used for the control of the ends for fan coil units, cooling/ heating system and HVAC system. Thermostat controls the motor of the valve, and make on/off through speed-down machine and reset spring to carry out the break/on of the hot/cold water in the pipe. 
Application Occasions:
Fan coil units, cooling/ heating system and HVAC system.
Operational mode:
Winner spring-return zone valve is
operated by on/off type actuator. The actuator adopts totally closed unidirectional hysteresis synchronous motor, having waterproof design and spring automatic reset function.

Installation and Suggestion:
The valve body should be installed into fan coil or in the radiator first, then you can install the actuator. The actuator and valve body can be connected directly with fast and easy installation way, without using any connection and calibration tools.
1. Feed line and return pipe of differential pressure should be controlled within the range allowed pressure difference.
2. The valve should be installed somewhere easy to install and maintain.
3. Horizontal installation, that’s mean the motor should be on the top of valve body to avoid humidity.
4. When install 2 way valve, B side should be in-fall and A side should be outfall (A,B signed on the bottom of valve body)
5. When install 3 way valve, inlet is on the bottom of valve (no signal shown)
