A fluid regulator includes a regulator body having a fluid inlet and a fluid outlet connected by a fluid flow path, with a portion of the regulator body forming a first chamber, an orifice disposed in the fluid flow path, a seat, and a control element disposed within the fluid flow path and shiftable between an open position spaced away from the seat and a closed position seated against the seat, with the control element arranged to respond to fluid pressure changes to control flow of a process fluid through the orifice. A diaphragm has a radially inner portion that is operatively coupled to the control element and a radially outer portion that is operatively coupled to the regulator body. The diaphragm includes a resilient redundant diaphragm sandwiched between two metal diaphragms, the diaphragm providing two separate seals.

Pressure loaded regulator with dual diaphragm and redundant seal

A balanced valve trim, a regulator valve with a balanced valve trim, and methods for modifying a regulator valve with a balanced valve trim assembly to accommodate different volume flow rates through the regulator valve are disclosed.

Mechanism and method to adjust size of balanced valve

Fluid regulator systems having reset apparatus and methods are described herein. A fluid regulator system includes a fluid regulator including a loading chamber and a supply chamber. The supply chamber is in fluid communication with a supply fluid. The system includes a first fluid control device having a loading inlet and a loading outlet. The loading inlet receives a loading fluid from a loading fluid source and the loading outlet is in fluid communication with the loading chamber. The first fluid control device controls fluid flow between the loading fluid source and the loading chamber. A second fluid control device includes a vent inlet and a vent outlet. The vent inlet is in fluid communication with the loading outlet and the loading chamber and the vent outlet is in fluid communication with a vent. The second fluid control device to control fluid flow between the loading chamber and the vent.

Pilot operated fluid regulators having a reset apparatus and related methods

Fluid regulator systems having reset apparatus and methods are described herein. An example reset apparatus for use with a fluid regulator system includes a first valve having an inlet to receive a loading fluid and an outlet in fluid communication with a loading chamber of a fluid regulator, and a second valve having an inlet in fluid communication with the loading chamber of the fluid regulator and an outlet in fluid communication with a vent.
