PILOT-OPERATED GAS PRESSURE REGULATORS Aperval 101 The APERVAL 101 is a pilot-controlled regulator for low- and medium-pressure applications. The APERVAL 101 is a fail-to-open regulator. It will open if: • There is no pilot loop supply; • The main pilot diaphragm is damaged. This regulator is suitable for use with previously-filtered, non-corrosive gases. Its truly "top entry design" allows all maintenance to be carried out without taking the body off line. > Design pressure: up to 17 bar (246,5 Psig) for spheroidal cast iron version up to 18,9 bar (274 Psig) for cast steel version > Operating temperature: -10 °C to +60 °C (14 °F to + 140 °F) > Ambient temperature: -20 °C to +60 °C (-4 °F to + 140 °F) > Range of inlet pressure bpu: 0,5 to 18,9 bar (7,25 to 274 Psig) > Range of outlet pressure Wd: 20 to 9500 mbar (0,29 to 137,75 Psig) > Minimum working differential pressure: 480 mbar (6,96 Psig) > Accuracy class AC: up to 5 (according to operating conditions) > Lock-up pressure class SG: from 10 to 30 depending on the outlet pressure > Available size DN: 2”- 3”- 4” > Flanging: class 125FF- 125RF- 150RF according to ASME B 16.1, and PN16 according to ISO 7005-2 Body Spheroidal cast iron GS 400- 18 ISO 1083 Cast steel ASTM A216 WBC Head covers Rolled or forged carbon steel Diaphragm Vulcanized rubber Valve seat Tecnopolymer Seals Nitril rubber Compression fittings According to DIN 2353 in zinc-plated carbon steel
