    I have had an great experience ordering from Wolfy! The communication was always quick and clear. Adding parts to your order after you made your payment is also accepted by Wolfy. They are also willing to hold your order for a little bit if you need time to decide what additional parts you would like to add. I ordered compression fittings.

Product Description

A stainless steel pressure regulator is a device used to control and maintain pressure in a system. It is typically used in applications where precise pressure control is necessary, such as in industrial settings or scientific laboratories. Stainless steel is an ideal material for pressure regulators because of its strength, durability, and resistance to corrosion.

The basic design of a stainless steel pressure regulator consists of three main components: a diaphragm, a spring, and a valve. The diaphragm is a flexible membrane that separates the high-pressure side of the regulator from the low-pressure side. The spring applies a force to the diaphragm, which opposes the pressure on the high-pressure side and controls the opening and closing of the valve. As the pressure on the high-pressure side changes, the diaphragm flexes and the valve opens or closes to maintain a constant pressure on the low-pressure side.

Features of stainless steel pressure regulator 

1. Corrosion resistance: Stainless steel is highly resistant to corrosion, making it a good choice for use in harsh environments or with corrosive fluids or gases.

2. Precision control: Stainless steel pressure regulators are designed to provide precise control over the pressure and flow rate of gases or liquids. They can maintain a constant pressure within a narrow range, even as the input pressure or flow rate changes.

3. Wide range of pressure settings: Stainless steel pressure regulators are available with a wide range of pressure settings, from low pressures of a few psi to high pressures of several thousand psi.

4. High flow rates: Stainless steel pressure regulators are designed to handle high flow rates, making them suitable for use in applications where large volumes of gas or liquid need to be controlled.

5. Versatility: Stainless steel pressure regulators can be used with a wide range of fluids and gases, including corrosive and high-purity gases. They can also be used in a variety of applications, from industrial processes to laboratory research.

6. Durability: Stainless steel pressure regulators are built to last, with rugged construction and high-quality components that can withstand the demands of tough industrial environments.

7. Safety features: Stainless steel pressure regulators may include safety features such as pressure relief valves, which protect against overpressure events that could damage equipment or cause injury.


Typical applications


1) Laboratory

2) Gas analysis

3) Process contral

4) Gas bus-bar

5) Testing equipment

Stainless steel pressure regulators may be used in a wide range of applications, including process control, gas and liquid chromatography, pharmaceutical manufacturing, and semiconductor fabrication. They are available in a variety of sizes, pressure ranges, and flow capacities to meet the needs of different applications. When selecting a stainless steel pressure regulator, it is important to consider factors such as the application requirements, the pressure range, the flow rate, and the compatibility with the fluid or gas being controlled.
