Modular Design
The modular design of Aperflux 851 pressure regulators allows retrofitting of an emergency monitor PM/819, slam shut valve and or silencer on the same body. The Aperflux 851 regulator is Truly a “top entry design” which allows ease of maintenance or retrofitting options in the field. The unique dynamic balancing system ensures an outstanding turn down ratio combined with an extreme accurate outlet pressure control.
Main Features
The APERFLUX 851 pressure regulator is a regulator of the piloted type for medium and high pressures. The APERFLUX 851 is a fail open type regulator and therefore opens in the event of:
- rupture of the main diaphragm;
- rupture of the pilot diaphragm/s;
- rupture of the pilot gasket;
- pilot circuit supply failure. The main features of this regulator are:
Materials
Body Cast steel ASTM A352 LCC for classes 300 and 600 ASTM A216 WCB for classes 150 and PN16
Head covers Rolled or forged carbon steel
Diaphgram Vulcanized rubber
Valve seat Stainless steel for DN ≤3” Carbon Steel with seal edge in stainless steel for size ≥ 4”
Seals Nitril rubber
Compression fittings According to DIN 2353 in zinc-plated carbon steel
