Pressure Relief Valve

Product Description:

1. The pressure relief valve is designed for energy-efficient, automatic control of positive pressure in clean air-conditioned rooms, maintaining a specific positive pressure within the room.

2. It is installed directly on the wall.

3. The valve features a counterweight-type adjustment mechanism that allows for adjustment of the opening pressure within a range of 5–50 Pa.

4. When the valve is closed, the air leakage rate meets the requirements for standard valves specified in (JG/T436-2014 Ventilation Airflow Control Valves for Buildings).

Product Features:

1. The valve body is made of 1.5 mm galvanized steel plate. The air inlet features an orifice plate, while the air outlet features a pressure plate with a counterweight.

2. The blade shaft is made of galvanized round bar or stainless steel round bar. When the valve width (W) exceeds 600 mm, a central partition is added to separate the blades, thereby reinforcing the structure.
