The PCV series dynamic differential pressure control valve is a room differential pressure control regulating valve, equipped with a controller and electric actuator. 

This product is suitable for situations where there is a pressure difference requirement in the room. The controller can intelligently recognize the opening and closing of the room door without the need for door magnetic signals, in order to reduce unnecessary pressure fluctuations caused by opening and closing the room door. The air valve controller can be connected to the centralized control system to achieve more intelligent indoor environment control and management.

 The product casing is cylindrical with flanges at both ends. There are 5 specifications of PCV, and the recommended air volume covers 10-3200 m³/h. The recommended air volume for each specification is shown in the table below, and the recommended working pressure difference is 150-750 Pa. 

Note 1: The model definition of FCV air volume control valve can be found in the technical specifications of FCV/PCV air volume and pressure difference control valve products. 

Note 2: If the required specifications and working air volume exceed the recommended range, please consult Tonghai for relevant technical support& Nbsp; 

§ Space saving: There is no need for straight pipe sections before and after the air valve. 

§ High airtightness: The valve body leakage reaches Class A, and the valve plate meets the leakage requirements of ordinary air valves (according to JG/T 436-2014 "Building Ventilation Air Volume Control Valves" standard). 

§ Valve body material: Made of 304 or 316 stainless steel, fully welded, fireproof, resistant to high and low temperatures, and corrosion-resistant. 

§  Controller: No need for door magnetic signals, can intelligently identify the opening and closing of the room door, supports RTU485 communication mode, and can be integrated with the control system.
