					<description><![CDATA[Constant Air Volume Valve Electric Valve

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.]]></description>
										<content:encoded><![CDATA[<p>Features of air volume control valve:<br />
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;<br />
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%;<br />
3. Air volume adjustment control range: air volume 50m3 / h ~ 1100m3 / h;<br />
4. Fast response: response time to control signal and duct static pressure change: &lt;1 second;<br />
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.<br />
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;<br />
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.<br />
8. High reliability, high quality price, courteous service: domestic quality products, reliable operation, quality and cheap,  provide 24-hour service.</p>

										<content:encoded><![CDATA[<p>Classification of PP duct valves</p>
<p>1. One-time regulating valve: If the system is not balanced, it is a regulating valve designed to achieve the required air volume. It is divided into flapper valve, butterfly valve, multi-leaf regulating valve, and three-way valve.</p>
<p>2. Frequently switched regulating valves: Mainly include fresh air valve, primary and secondary air return valve, exhaust valve (including exhaust valve for comprehensive exhaust and partial exhaust).</p>
<p>8. Automatic control valve: Mainly used for automatic adjustment of fresh air, primary return air, and secondary return air. In addition to meeting the requirements of frequently-on-off regulating valves, it should also have good regulating characteristics.</p>
