Description
Aperval is a pilot-controlled pressure regulator for medium and low pressure applications.
Aperval is normally a fail open regulator and will open specifically under the following conditions:
- If the main diaphragm fails
- If there is no sensor line input
This regulator is suitable for use with previously-filtered, non-corrosive gases.
Features- Design pressure: up to 362 PSIG (25 bar)
- Temperature: Pietro Fiorentini regulators are suitable for a minimum operating ambient temperature:
- -40° to 140° F with a Carbon Steel Body
- -4° to 140° F with a Cast Iron Body
- If the following conditions are met:
- Inlet flowing gas temperature shall be always higher than -4° F
- Inlet flowing gas shall be filter, clean and without any liquid impurities
- Range of inlet pressure bpe: 7.25 to 362 PSIG (0.5 to 25 bar)
- Range of outlet pressure Wh: 2” w.c. to 137.5 PSIG (5 mbar to 9,500 mbar) depending on installed pilot
- Minimum working differential pressure: 6.52 PSIG (450 mbar)
- Maximum working differential pressure: 275.5 PSIG (19 bar)
- Accuracy class AC: up to 2.5 > Closing pressure class SG: up to 5
- Available size DN: 1”, 2”, 2-1/2", 3”, 4”
- Flanging: class 150 RF or RTJ according to ANSI B16.5 and PN25/40 according to ISO 7005
