American Ligao Rego LV-4403C4 High Pressure Gas Regulator

Reasonable price, good effect and high performance application.
Applicable to both liquid and gas media.
Compact design, easy to install. *The indirect acting design helps the regulator deliver constant pressure even as tank pressure drops.
Indirect acting design provides better performance, even in very low temperature environments and very low tank pressures, as well as large flow requirements.
Stable output pressure, especially in low temperature weather, contributes to the stability of the function of the secondary regulator, ensuring the best performance.
Equipped with 1/4 inch female threaded port for easy connection of pressure gauges.
The molded diaphragm is held between the body and the bonnet and has a sealing O-ring.
Fully painted with bright red paint, this paint has anti-corrosion protection function.
A choice of four adjustable ranges for optimal performance.
The connection between the valve cover and the valve body, all assembly work is completed in the United States.

How do gas pressure regulators work?

There are several different types of gas regulators, but they all work on the same principle.
The simplest type is the single-stage regulator, which reduces the gas pressure in the cylinder to the level required by the equipment in one go.
The basic components of each regulator include a spring, a thin flexible rubber metal disc called a diaphragm, and a valve.
While not every gas regulator has a pressure gauge, we have included them as well to help show how the pressure changes as the gas enters and leaves the regulator.

Step 1: The gas enters the regulator When you connect the gas regulator to the cylinder and open the cylinder valve, high pressure compressed gas rushes into the valve cavity through the inlet. ,
Step 2: The gas will soon fill the valve chamber, as indicated by the inlet pressure on the left.
Step 3: Diaphragm moves down When you turn the gas regulator control button clockwise to increase gas flow, it presses down on the spring, which forces the diaphragm down and pushes the valve stem open.
Step 4: The gas enters the low pressure chamber Opening the valve stem allows gas to flow into the low pressure chamber. Now, the gas pushes the diaphragm up, creating an opposite force on the spring.
Step 5 : Diaphragm Stabilization When the upward force created by the gas pressure under the diaphragm reaches the same level as the downward force exerted by the spring, the diaphragm stops moving and becomes stable. This allows the gas to start flowing into the device at a smooth, even rate.
Step 6 : Cylinder Pressure Drop After a while, as the gas runs out, the pressure in the cylinder begins to drop. This has a knock-on effect on the pressure in the valve chamber, which also begins to weaken. When the force of the upward pressure from below decreases, the diaphragm begins to move downward, pushed by the spring. This makes the valve wider and allows more gas to enter the low pressure chamber.
Step 7 : Outlet Pressure Rise As the gas condenses in the low pressure chamber, the outlet pressure begins to rise, as indicated by the gauge. There is now almost no gas left in the intake.
Step 8: Cylinder Bleed When the cylinder runs out of gas, or when the cylinder valve is closed because you have finished using the device, the air inlet closes and both gauges return to zero when the last gas leaves the regulator.
