Pressure vacuum release valve,Its used for the Dust Collection System:
When the temperature of the air exhaust and abnormal change, protect the container from excessive positive pressure and negative pressure. Each Ash silo setting a 508 type vacuum pressure relief valve to protect the silo long-term stability and safety of operation.
SFF508 Pressure Vacuum Relief Valve

The working principle:
1. The rest position (seal) :
When the silo internal pressure within the valve pressure value of the selected, bonnet hold position. Due to the pressure in the silo is a masterpiece of top of the flexible diaphragm is closely contact with the diaphragm to the seat, so as to achieve the effect of the seal.
2. Pressure release:
When the silo pressure increasing pressure to the selected value, the cabin pressure overcome the weight of the valve cover, lifted the cover from the seat, at the same time pressure to empty until bin selected value, the internal pressure to the valve cover back to its normal position.
3. Vacuum release:
When the silo pressure below atmospheric pressure, produce a vacuum in the silo, when valve selected vacuum value, due to the pressure on the diaphragm, lift ring vacuum floating position at this time air into the bunker, know the vacuum value is less than the selected value in the bunker, the vacuum ring back to the normal position, depend on the diaphragm.
