How does a tescom regulator work?

In a pressure reducing regulator, the outlet pressure drops (or droops) as the flow increases. As the flow decreases, the P2 pressure goes up, or recovers to just above the original set point. Droop is the result of loading force changes in the regulator, and is caused primarily by the load spring.

How do you read a regulator curve?

To locate the right curve for your system, look for (1) the right set pressure; (2) the right inlet pressure; and (3) the right range of flows. The best way to select a regulator for your application is to examine its flow curve, which is often provided by the manufacturer.

What is an air loaded regulator?

A dome-loaded regulator uses a fluid pressure, normally air, on top of a sensing element to provide the setpoint pressure. The sensing element is typically a diaphragm (common for lower pressures) or a piston (common for pressures above 10 to 20 bar).

How does a dome loaded regulator work?

Dome loaded pressure regulators are operated by gas pressure in the dome. In contrast to spring loaded regulators, dome loaded pressure regulators regulate the output pressure based on the pressure within the pre-loaded dome. The pressure within the dome can be controlled internally and externally.

How does a back pressure regulator work?

A Back Pressure Regulator (BPR) is a device that maintains a defined pressure upstream of its own inlet. When fluid pressure in the process at the inlet of the BPR exceeds the setpoint, the regulator opens to relieve the excess pressure.

What is captured vent regulator?

Captured venting configuration includes extra port to pipe away expelled fluids from a regulator’s vent valve. Non-venting feature available for hydraulic or other applications where venting is not desirable. FLOW CAPACITY – Cv. Cv is a measure of regulator flow capacity.

How do you calculate the flow rate of a regulator?

To determine the maximum flow through a regulator use either: – the seat orifice area formula, or – the nomograph. As long as there is a choked (critical) flow, (P1 = 2 x P2 at least), the flow which you will find on the nomograph is the maximum flow with the valve wide open.

What is the difference between pressure regulator and back pressure regulator?

While a Back Pressure Regulator holds pressure on a vessel, a Pressure Reducing Regulator is designed to precisely regulate the flow of gas. It creates and holds a downstream set point.

How do you adjust a back pressure regulator?

To adjust the set point, turn the adjusting screw on top. The spring pushes down on the diaphragm assembly, which positions the pilot plug. The pilot plug then allows gas from upstream to push down on the diaphragm. The flow through this regulator is from underneath the plunger.
