heating ball valve, two port motorized valve for hot water flow control, HVAC
The zone valves internally consists of a motor to move the ball valve to the open position, a spring to return it to the closed position, and a microswitch which is activated when the valve is fully open. In a heating system when heat is required, power is applied to the motor to open the valve by the thermostat detection.
HVAC system heating, ventilation, air conditioning
Fan coil units
Sturday valve body with reasonable structure design, and best material to be used
fluoro rubber (green)
Resistance to high temperature, oil, corrosion, chemicals, Work temp.: —30℃+280℃.Quadruple seals, minimize the risk of leakage.
Drain just in case leakage happens
Between nut and valve body, extra external leak proof, reduce the possibility of internal leak
