Electric valves VA4303 electric two-way valve body materials Material Description: Forged Brass Stem Material: brass sealing material: nitrile rubber (NBR) drive Chassis: stainless steel drive cover: aluminum electric two-way valve Product Overview Gv4303 series electric control valve for central air conditioning system, heating system pipe open or closed, to achieve the purpose of the control room. Controlled by a one-way valve hysteresis synchronous motor, spring return. When the valve is not working in a normally closed state, when the need to work, provided by a thermostat valve opening signal to the electric valve connected to AC power and action, open the valve, chilled water or hot water into the fan coil, for room air-conditioning or heating; when the temperature reaches the thermostat set point, the thermostat so that the electric valve power, the return spring to the valve closed, thus cutting off the flow of water into the fan coil. Through the valve closed and open, so room temperature is always maintained at a temperature range of the thermostat setting. GV4303 series of electric valve with optional auxiliary switch, used to control other devices; and the use of different forms of taking over for the voltage to meet different needs. GV4303 series of electric valve, flexible operation, reliable and durable, low noise, and be able to withstand in the concealed fan coil unit often occurs in hot and humid environment.

For high-rise buildings should be used valve on the bottom of the manifold. 2, the motor housing should prevent dripping water infiltration. When the valve is installed in a horizontal pipe, mounting position and the angle between the vertical plane should not exceed 85 ℃ (see Figure D) 3, when the valve is mounted in a vertical pipe, the motor housing is necessary to prevent infiltration of dripping 4, the manual lever: When the manual lever and press the arrow pointing to slowly move into the notch stuck, the valve is normally open. Whenever electric current through the first valve, manual lever will then be set to automatic position.
