(✻) Minimum pilot pressure varies with differential pressure, see page V402-7.
(1) Calculation of the minimum pilot pressure at a ∆P of max. 10 bar with allowable backpressure (backpressure not recommended with liquids as waterhammer mayoccur).
- 32 and 50 mm operators, 4 bar minimum pilot pressure version: add 2 bar to the minimum pilot pressure of chart V or X, page V402-7.
- 63, 90 and 125 mm operators, 4 bar minimum pilot pressure version: add 1,5 bar to the minimum pilot pressure of chart VI, VII or VIII, page V402-7.
