Description
The type 75HR air relay (or pilot operated pressure regulator) uses signal pressure to control accurately output pressure over a wide range of flow and supply pressure variation. Sizes range from 1/4″ – 1/2″ BSP & NPT.
The type 75HR provides extra fast “blowdown” for very rapid release of output pressure. The extra relief feature makes this relay suitable for cylinder return stroke actuation, air hoists and similar applications requiring fast exhaust.
Flow capacity is given for 1.4 bar signal and 6.9 bar supply
Available on request:
signal output pressure ratios 1:2, 1:4 & 1:6
