Overview

The residual pressure valve is a device set up to maintain a certain indoor static pressure and achieve energy free automatic control of positive pressure in air-conditioned rooms. The residual pressure valve is a one-way air flow regulating device that adjusts the opening degree according to the static pressure difference and balances the air pressure with the position of the heavy hammer. The air flow through the residual pressure valve is generally between 100-1200m3/h, and the pressure difference is maintained between 5-40Pa.

Product Details

The residual pressure valve is a device set up to maintain a certain indoor static pressure and achieve energy free automatic control of positive pressure in air-conditioned rooms.The residual pressure valve is a one-way air flow regulating device that adjusts the opening degree according to the static pressure difference and balances the air pressure with the position of the heavy hammer. The air flow through the residual pressure valve is generally between 100-1200m3/h, and the pressure difference is maintained between 5-40Pa.

Characteristics of residual pressure valve

1. Close tightly, responsive

2. Easy to adjust and aesthetically pleasing in appearance

3. No energy consumption

4. The exhaust wind speed does not affect the indoor airflow state

5. The position of the heavy hammer can be adjusted according to the requirements of air volume, pressure difference, and temperature (such as 70 ℃)

Application of residual pressure valve
The residual pressure valve has good adaptability to rapid static pressure changes and is generally recommended to be installed on the outer wall of the downwind side between clean rooms with different static pressure differences, and should not be installed in indoor airflow areas that significantly affect the downstream side. The device consists of an outer frame, a valve plate, and a counterweight. The valve plate has a larger opening angle of 45 ° and can be widely used in purification workshops or clean rooms to maintain a positive pressure difference between indoors and outdoors, allowing excess indoor air to be discharged and preventing outdoor air from entering.
