The pressure relief valve has excellent adaptability to abrupt changes in static pressure. It is generally recommended to be installed on the downwind side of the exterior wall between cleanrooms with different static pressure differences, and should not be placed in locations that would significantly affect the indoor air flow on the downstream side. When the smoke-proof staircase is pressurized for ventilation while the ante room is not, a pressure relief valve may also be installed in the partition wall between the staircase and ante room. The device consists of an outer frame, a valve plate, and a counterweight. The valve plate can open to a maximum angle of 45°, and is widely used in clean rooms or clean workshops to maintain a positive pressure difference between the indoor and outdoor environments, allowing excess indoor air to be exhausted and preventing outdoor air from infiltrating.
