different grades. Sleeve simple to change.

Operating pressure = max. 4.0 bar
Pilot pressure = max. 6.5
Differential pressure = max. 2.5 bar
Closing pressure = P1 + 2.5 bar to DN 32, P1 + 2 bar from DN 40 on
Vacuum: If vacuum is greater than -100 mbar, vacuum compensation
should be provided on the control side.
Mounting_position: any, at horizontal mounting pilot port
preferably at the top
Temperature_range: 0 °C to max. 100 °C / 32 °F to max. 212 °F,
