Electric two ventilation valve use range and product features

. Pipe is used to control the cold water or hot water air conditioning system of open or closed, to achieve the purpose of the control room temperature.
　　
　　. Drive from single hysteresis synchronous motor drive, spring return pneumatic valve, pneumatic valve does not work in a normally closed state, when the need to work, provided by a thermostat open signal to make the electric pneumatic valve connected to the ac power and action.
　　
　　. 。 Open the pneumatic valve, chilled water or hot water into the fan coil units, to provide room air conditioning or heating, when the room temperature reaches the thermostat setting, the thermostat to power electric pneumatic valve, reset spring to close the pneumatic valve, thus cutting into the fan coil currents, closed by a pneumatic valve and open, make the room temperature always stay in the temperature control setting temperature range.
　　
　　. 。 ZYFT series electropneumatic valve drive and pneumatic valve adopts threaded connection method, in the pneumatic valve is installed, then install the drive. Field assembly and connection flexibly and conveniently. Drive the plane design can be installed close to the wall, to take up the space is little, products are reliable and durable, low operating noise, and can often appear in the concealment type fan coil units of high temperature and high humidity environment and reliable work.

choose aluminum bracket and plastic shell actuator, small volume, light weight

u choose permanent magnet synchronous motor, with magnetic hysteresis clutch mechanism, has reliable self-protection function

u: suitable for a variety of control signal increment ( Floating point) , voltage ( ~ V) And the current ( ～mA）

or u have ~ V ~ (mA feedback signal Optional)

u use a metal gear transmission gear, greatly improving the service life of the drive

u low power consumption, big output power, low noise,

u pneumatic valve body has cast copper, cast iron, cast steel, stainless steel variety of material to choose from, in order to suit the requirements of different working medium and temperature

u pneumatic valve has two kinds of threaded connection and flange connection, easy installation, the construction conform to the IEC international standards

u pneumatic valve body structure with two-way pneumatic valve ( Single seat) , balanced two-way pneumatic valve ( Balance type) Shunt pneumatic valve, three-way merge and tee

it is divided into direct acting and pilot operated.
