Pressure Control Valve: The Pneumatic Door Closer
Pneumatic door closers are usually installed on door jambs or over doors found in large offices and other institutions. The doors are generally heavy, hence the need for pneumatic door closers. Upon opening the door, the air inside the door closer becomes compressed. When nothing is holding the door open anymore, the door closer uses that same compressed air pressure to push the door shut. This releases the pressure from the pressure control valve, and once the door is shut, the air pressure inside returns to normal.
Other features
Pneumatic door closers have other features. Most door closers can be adjusted to change the speed that the door closes. This mainly involves adjusting the pressure control valve with a screwdriver to control the air pressure to select how fast or slow the door closes. Some door closers use hydraulic dampeners, while others simply use standard springs.
The difference between pneumatic and hydraulic door closers
Hydraulic mechanisms for door closers use a pressurised system powered by compressed liquid stored in a tank inside the door closer. When the door is opened, pressure is applied to the liquid, and this is distributed throughout the mechanism. So, when the liquid is pushed back in one area, and the door is no longer held, the liquid is forced into another area, and the door closes.
The primary difference between the two is quite apparent: Pneumatics uses compressed air, hydraulics uses compressed liquid. Other variable differences between the two systems are found in:
- Load weight
Both pneumatic and hydraulic door closers can handle heavy and more oversized doors. However, hydraulic door closers can handle heavier loads, such as large roller shutters, industrial gates, and heavy factory doors.
- Shock resistance
Both door closers have high shock resistance. But hydraulics offer greater resistance to impacts and shocks. This makes hydraulic door closers the preferred option for heavy industrial environments.
- Environmental impact
While pneumatic doors are noisier, hydraulic doors come with the risk of fluid leaks if the mechanism or valves inside are damaged. Pneumatic door closers are also cleaner, making them the hygienic option for enclosed environments, with no danger of liquid contamination in such premises as food supply chains.
