Breathing device UD 2-80

The pneumatic breathing device (UD) of tanks with fire fuse is designed for the system of vapour removal from the tank when filling and draining the oil product.
Breathing device opens, preventing dangerous increase or decrease of pressure in the tank, and ensures tightness of the tank in case of its overturning.
UD is designed for operation in areas with moderate climate at ambient air temperature from minus 40 to plus 50 ?.
The fire fuse included in the breathing device protects against flame penetration, is made in explosion-proof version and corresponds to the operating conditions in terms of explosion protection and fire safety requirements.
Overpressure when the breathing apparatus is turned 180 deg. 0,025 (0,25) MPa (kgf/cm2)
Pressure of full opening of the shutter:
overpressure from 0,0063 (0,06) to 0,0080 (0,080) MPa (kgf/cm2)
vacuum from 0.0025 (0.025) to 0.0032 (0.032) MPa (kgf/cm2)
Overall dimensions 127x201x154 mm
