A gas regulator is a device that controls the output pressure of gas. It is connected to the main valve of a gas tank and has an adjustment screw that controls the spring to open and close the valve in small increments. The regulator can be tightened by either turning the screw clockwise or counterclockwise. There are two ways to adjust the gas regulator: by turning it counterclockwise or clockwise. Then, adjust the pressure output according to the needs.

Propane
The heart of your propane gas vapor system is the propane gas regulator. Though the regulators vary widely between manufacturers, there are some basic parts that are common to all of them. These components include a body and cover that are usually color-coded for different types of services. The outlet port is the point where the vapor from your source gas enters your regulator, while the orifice controls the amount of vapor that passes through.

If your propane supply is not adequate to fuel your propane appliance, you can install an automatic changeover regulator. It automatically switches to the second tank when the first one runs out of propane. In addition, the regulator changes color when the first tank is drained. Its outlet is 3/8'' NPT female.

Dual-stage
A dual-stage gas regulator is a high-purity device designed for use in industrial applications that require the regulation of pressure to a particular level. This type of regulator has upstream and downstream pressure gauges as well as a relief valve. A wide variety of cylinder connectors and outlet connections allow the user to easily adjust the regulator to the correct working pressure for the application. A dual-stage gas regulator is also suitable for welding.

The two-stage model is highly versatile and covers the entire spectrum of service requirements. These units are suitable for fusion welding as well as high-integrity laboratory applications. They have adjustable spring compression and are UL144 certified. These regulators are made in Italy and feature high-quality construction and strict quality control. These devices are rated for pressures from 160 to 500 MJ/h. They come in different sizes.

Diaphragm
Gas regulators have a set spring that controls the flow rate and maintains the downstream pressure. These regulators work by detecting the pressure downstream and altering the spring valve so that gas can flow to the inlet. A similar mechanism can also be found in umbrellas, which use a diaphragm that prevents water from flowing on people. Similarly, a gas regulator has a set spring that regulates the outlet pressure, and a spring that acts as a diaphragm.

The GENTEC(r) R53SL Series Single-Stage Tied Diaphragm Regulator has a specially designed link that prevents valve seat creep, which can reduce the performance and life of the diaphragm. It also features a high-flow mesh filter that is installed before the gas enters the seat. This filter is attached to the seat and can be easily swapped during maintenance. The filter will catch any debris before entering the seat, thus preventing the diaphragm from being overloaded with debris.

Filter
A gas regulator filter removes particulate matter from the flow of fluid or gas. The preferred embodiments are made of fiber glass which is non-flammable, non-hydroscopic, chemically inert, and inexpensive. The filter has a high capacity to trap particles, and is often a toroid shape. It is easy to install, and provides a durable, effective filter. In general, the filter is composed of a continuous glass filament or yarn woven into a woven pattern.
