Pressurized Relief Valve For Industrial Types
A compressor pressure relief valve or PPRV is a special device that should be installed on every industrial type compressor. This is because this device helps in reducing the pressure of the air being fed to the compressor and prevents any loss of power as well. There are three different types of PPRVs available in the market. They differ in their operation modes and different sizes. An example of a PPRV is the HPV which is an extremely popular option among the users because of its practicality and affordability. The other two PPRVs are the DPVC and the ADVPV.
The PPRV works by sensing the difference in pressure between the incoming air stream, at the point where the volume of the incoming air is higher than the volume of the outgoing air. After sensing this difference, it starts calculating the pressure. If the pressure is less than a preset value, the device will stop functioning. This is because the incoming air is being taken from an area that is below the preset pressure level. So, the PPRV will take the incoming air and set it against the preset pressure and then release it gradually.
The pressure relief valve also comes with a timer, which controls the period in which the pressure will be released. The timer is normally controlled by a solenoid. When the pressure in the compressor increases, the timer will be activated. As a result, the solenoid will be activated also and the valve will then be closed and the compressor will start taking air again. For reducing the vibrations caused by the compressed air, the PPRV has a two-way valve which works like a transducer.
