boiler zone valve/ Zone heating valves for heating and cooling unit, with thermostat

Product Description

The electric zone valves on central heating and cooling systems, heating boilers, it controls hot water heat or cold water. In all cases, when the zone control valve is fully open, an "end switch" inside the valve tells the heating system's circulator to begin operating, causing hot water to flow through the zone.
Our zone control valve is a range of 2-way motorized zone valve, which is with motor actuator for use in heating and cooling system. The brass or stainless ball valve is available in DN15-32, PN10 with thread connection. The actuator is controlled by 2-point signal and is recommended for on/off function, available for 230V AC, 50/60Hz or DC power supply.

Features

• Metal gearbox and metal gear design, low noise, perform reliably
• Long service life: more than 100000 circles
• Electric limit and machinery limit design, located accurately, avoid gear run continuously.
• Mufti-angle assembling, easy to install
• Float ball structure, no leakage, especially suitable for heavy pollution conditions.
• Can work in boiler water room, good substitution for solenoid valve

Application

Advantages

• Sturday valve body with reasonable structure design, and best material to be used

• Three wires and two control points (DC3-6V / DC12V / DC24V)

1. Connecting SW to OPEN, the valve opens , getting the position ,automatically power off, the valve remain fully open position

2. Connection SW to CLOSED, the valve close , getting the position ,automatically power off, the valve remains side passes position (fully closed)

Note: AC24V/AC220V can only be used for 50K series electric valves
