Customized air ducting check valve
Product description
Features of air volume control valve
1. Pressure independent control: the valve body in the valve body
to install mechanical pressure compensation components, according
to the air inlet and outlet pressure pressure for automatic
pressure compensation to ensure that the wind valve in the static
pressure changes to maintain a constant set of air flow; Pressure
drop 150Pa ~ 750Pa within the scope of pressure to achieve
independent control;
2. Accurate air flow control: through the air flow speed controller
component positioning, air volume can be quickly adjusted, air
volume control accuracy of ± 5%;
3. Air volume adjustment control range: air volume 50m3 / h ~
1100m3 / h;
4. Fast response: response time to control signal and duct static
pressure change: <1 second;
5. Anti-dust, maintenance-free: Compared with the conventional
butterfly valve similar products, because this series of products
without air flow (or pressure) sensor, so the sensor caused by
dirty plug system failure caused by security incidents, improve
product stability And durability.
6. highly anti-corrosion treatment: the use of PP plastic body
material, is the product can be high-intensity corrosion conditions
in the long-term safe operation;
7. Control mode switching and remote communication function: This
product selection PLC programmable controller, with control mode
switching function (software with a variety of operating modes,
just set to change the valve running control state) and remote
communication function.
8. High reliability, high quality price, courteous service:
domestic quality products, reliable operation, quality and cheap,
provide 24-hour service.
Applications
1. Constant air volume control (CAV series): suitable for static
pressure changes in the case, to maintain the set air volume of the
occasion.
2. VAV control (VAV series): for closed-loop feedback variable air
volume control occasions.
