3 port zone valve, electric heating ball valve with step motor actuator DN15
Why sometimes a zone will fail? The possible reason may be from the valve iteslf, or a faulty of thermo stat. In the interest of improving efficiency and occupant comfort, such systems are commonly divided up into multiple area zones. This brass or stainless motorized zone valve is installed right after the boiler and circulator that's the hot side, or at the end of the zone circuit that's the cold side. It's a heating ball valve, which is a specific type of valves and are used to control the flow of water or steam in a hydronic heating or cooling system.
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
