Residual pressure valve works?

Residual pressure valve works?
Residual pressure valve can be used in clean room or clean room, indoor and outdoor used to maintain a positive pressure, excess air from the room, to prevent outside air intrusion.
How it works: When the pressure exceeds the standard purification room pressure, valve gate automatically opens when the pressure is lower than the standard, the valve closed state recovery, to balance the pressure. Internal air pressure to prevent the purification room squeeze caused by the noise and the possibility of a burst. Residual pressure valve manifold types There are many different applications have different nuances, welcome to inquire details residual pressure valve.
Residual pressure valve characteristics
1. Installation in the form of a wall-mounted, wall thickness within 30 ~ 50mm can be adjusted.
2. Hammer position can be adjusted according to the amount of wind, pressure requirements.
3. Surface paint or electrostatic spray (spray color is generally white, can also be specified by the user). If other requirements should be stated in the order, according to the user's needs, and manufacture of various specifications. And generally use a differential pressure gauge. Can be custom made according to size.
4. In order to prevent contamination of clean rooms, indoor positive pressure must be maintained, if the clean room pressure is too high, causing the doors easy switch, thus the use of pressure relief dampers to keep the positive pressure clean room. Air flow through the pressure relief damper is generally between 100-1200m3 / h, maintaining the pressure differential between 5-40Pa.
