The VA7010 series switch type electric two way valves consist of VAA7010 series valve actuators and VAV7010 series copper valves. It is used to control the opening or closing of pipes in cold or hot water air-conditioning systems, so as to achieve the purpose of controlling room temperature. The driver is driven by a one-way hysteresis synchronous motor and the valve springs are reset. The valve is normally closed when it is not working. When it is needed to work, the thermostat provides an open signal to enable the electric valve to switch on the AC power supply. The valve is opened, and the cold water or hot water enters the fan coil to provide air conditioning or heating for the room. When the room temperature reaches the set value of the thermostat, the thermostat makes the electric valve power off. The reset spring closes the valve, thus cutting off the flow into the fan coil. Through valve clearance

Closed or opened to keep the room temperature in the temperature range set by the thermostat.

The driver of VA7010 series electric valve is connected with the valve body by a screw sleeve. The driver can be installed after the valve is installed. It can be assembled on site. The connection is flexible and convenient.

The planar design of the driver can be mounted close to the wall and occupies little space. The product is reliable and durable, low noise, and can work reliably in the high temperature environment which often appears in the concealed fan-coil unit.

Material description

Body material: forging brass.

Sealing material: nitrile rubber (NBR)

Driver cover: flame retardant ABS engineering plastics

Medium temperature: < 94 C

Stem material: stainless steel (A1S1302)

Drive chassis: die cast aluminum alloy

Working medium: water

Operation and precautions

The motor housing prevents drip penetration. When the valve is installed in a horizontal pipe, the angle between the installation position and the vertical plane should not exceed 85 degrees. When the valve is mounted on a vertical pipe, the motor housing must prevent drip dripping.

When the manual lever moves slowly along the arrow pointing and clamping in the gap, the valve is in the normal switching state. Whenever the current first passes through the electric valve, the manual lever will be set to the automatic position.
