PRV valve

Pressure reducing regulators, also known as pressure reducing valves, are mechanical devices which achieve automated pressure control without an external power source. Pressure reducing regulators reduce a high, often variable upstream pressure to a lower steady outlet pressure despite varying flow demand from the equipment it is supplying. To match this demand, the pressure reducing regulator valve throttles, allowing more flow when demand increases and choking off the flow when demand decreases.

This session covers an overview of the sizing and selection of regulators, considerations, details to look out for when selecting self-operated and pilot-operated regulators, and resources for more information.

Spring-loaded or direct-operated regulators balance spring force with outlet pressure via a diaphragm to control regulator. It is known for its simplicity and cost-effectiveness.

Regulating valve

High-capacity regulators designed for high-pressure gas as it moves along the transmission pipeline through city gate stations & farm taps.

Regulator

We move on to pilot-operated regulators in this session. This webinar discusses the principle of operation and comparison with self-operated regulators.

The Fisher 627BM is the newest product extension to the 627-product family. The balanced trim design enables this pressure regulator to achieve a 1,500psig inlet pressure rating while using a large 9/16” orifice. With a flow rate capability that is five times the traditional 627, the 627BM can displace oversized pilot-operated regulators and parallel runs of direct-operated regulators.

Butterfly valve

These are engineered for pressure control in sanitary environments in pharmaceuticals, biotechnology, food and beverage, cosmetics, and chemical industries.

A pilot-operated regulator amplifies slight changes in outlet pressure to the main valve, offering larger flow capability and maintaining outlet pressure closer to the setpoint.

Pilot-operated regulators are inherently more accurate and handle higher flow capacities than direct-operated regulators. They are more sensitive, with the ability to flow more gas for a given change in downstream pressure. Pilot-operated regulators tend to offer larger valve body sizes as direct-operated regulators are aimed to be simple, robust and cost-effective.

What is a pressure regulator for? What does a pressure regulator do? On a very basic level, regulators provide a way to control the pressure of gas or other fluids to downstream processes or customers. Self-operated regulators work to meet or fulfill downstream demand while keeping downstream pressure constant.

Pilot-operated regulators are a two-part system with a pilot and a main valve. The pilot ( the brains) provides a small change to the main valve ( the brawn) opening or closing the main valve depending on the downstream pressure.  Pilot-operated regulators provide larger flow rates and greater accuracy capabilities to users.
