The advantages and performance of the pneumatic valve 1 to breathe

advantages: light weight, gas flame arrester has simple structure. Easy maintenance, easy installation. Water pressure test. Low temperature resistant antifreeze connectivity qualified: - ℃ operating hours, pressure pneumatic valve disc, vacuum pneumatic valve plate and seal ring are no deformation phenomenon. Fully comply with the requirements of specification. Room temperature ℃ continuous operation hours, action time, pressure pneumatic valve disc, vacuum pneumatic valve plate and guide bar interface without any signs of wear and bruised, guide rod no stuck phenomenon.
breathing the characteristics and performance of the pneumatic valve:
no penetration and deformation phenomenon. Breathing pneumatic valve of low temperature resistance in the air relative humidity is greater than the minimum temperature of - % ℃, breathe the pneumatic valve pneumatic valve body can withstand. Mpa water pressure. After hours of frozen, the pneumatic valve opening pressure conform to the requirements of the pressure of work, allowing the differential plus or minus pa
high sensitivity, GTQ type vent pneumatic valve plate parts moves. After the completion of the action, ensure the seal. Breathing with sufficient space in pneumatic valve pneumatic valve, to ensure that the tank ventilation. Breathing before I go to work pressure pneumatic valve: nominal diameter in mm or less its leakage or less. M/h or nominal diameter mm its leakage or less. M/h when breathing pneumatic valve to work pressure, pneumatic valve plate immediately open, ensure the normal order of the tank ventilation requirements. Characteristics and performance:

antifreeze performance is good. The pneumatic valve is a device on a fixed roof tank ventilation device, the new pipe flame arrester material used: cast iron, cast steel, stainless steel, aluminum and good resistance to corrosion. Pneumatic valve, pneumatic valve sealing ring is made of stainless steel material of tetrafluoroethylene. Resistance to low temperature. To reduce oil product evaporation loss, control the tank pressure. This pneumatic valve has the ventilation rate, small amount of leakage and corrosion resistant, antifreeze performance is good. To automatically adjust the oil storage tank inside and outside pressure, etc.
