Pilot-operated gas pressure regulators


Terval AP is a trivalent system, which combines three devices in one: the regulator, the monitor, and the slamshut.
The pressure regulator and the monitor are pilot controlled, for medium and high pressure applications.
It is particularly suitable for use within the framework of installations for the distribution of natural gas, as well as for supply networks for civil and industrial use.
The accuracy of the regulated pressure, the high rangeability ratio, together with the fast adaptation to changes in the operating conditions, even in the presence of abrupt changes in the flow rate, make the regulator Terval AP particularly suitable for use in gas supply installations of electric power generation stations (Turbogas).
The Terval AP can be supplied in two versions, according to European standard EN 334:

  • Terval AP/FC Regulator Fail to Close
  • Terval AP/FO Regulator Fail to Open
It is truly a TOP ENTRY design, which confers to the regulator management advantages, for example the ability to performs full maintenance without uninstalling it from the connection pipe.
