    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

Product Description of Nitrogen Pressure Reducer High Pressure Gas Regulator Dual Stage Gas Regulator


Two-Stage Pressure Regulator Using Pressure


Two-stage pressure regulators are typically used in applications where a consistent and precise output pressure is required, regardless of fluctuations in the input pressure. The two-stage design provides greater precision and stability over a wider range of input pressures compared to single-stage regulators.

The specific pressures for the use of two-stage pressure regulators can vary depending on the application and the type of gas being regulated. However, some general pressure ranges for two-stage pressure regulators include:

  • Inlet pressure range: typically between 500 and 3000 psi (pounds per square inch)
  • Outlet pressure range: typically between 0~25,0~50,0~100 and 0~250psi
  • Delivery pressure range: typically between 0 and 15 psi


Features and Advantages of Two-Stage Pressure Regulators


  • Greater precision and stability: Two-stage pressure regulators are designed to provide a more precise and stable output pressure over a wider range of input pressures. This is achieved through a two-stage design that reduces the pressure in two steps, resulting in a more consistent and accurate output pressure.
  • Consistent flow rates: Two-stage pressure regulators are able to maintain a consistent flow rate, even when there are fluctuations in the input pressure. This is important in applications where a consistent flow rate is required, such as in gas chromatography, welding, and other industrial processes.
  • Better performance in low-pressure applications: Two-stage pressure regulators are often used in low-pressure applications, where a single-stage regulator may not be able to provide the necessary precision and stability. The two-stage design of these regulators allows for better performance in these types of applications.


  • Improved safety: Two-stage pressure regulators are designed with safety features such as pressure relief valves and gauges that allow for easy monitoring of the pressure levels. This helps to ensure that the regulator is operating safely and within the recommended pressure range.
  • Versatility: Two-stage pressure regulators can be used with a wide range of gases, including oxygen, nitrogen, argon, helium, and CO2. This makes them a versatile choice for a variety of industrial and laboratory applications.

Overall, the features and advantagesof two-stage pressure regulators make them a popular choice for applications that require precise and stable control of gas pressure. They offer improved performance, safety, and versatility compared to single-stage regulators, making them a valuable tool in many industries and laboratory settings.

Q1. What products can you provide?

Re: High pressure regulator, cylinder gas regulator, ball valve, needle valve, compression fittings(connections).


Q2. Can you make the products based on our requests, such as connection, thread, pressure and so on?

Re: Yes, We have experienced techincal team and can design and produce the products according to your requirements. Take a pressure regualtor for example, we can set the range of pressure gauge according actual working pressure, if the regulator is connected to a gas cylinder, we can add an adaptor such as CGA320 or CGA580 to connect the regulator with the cylinder valve.


Q3. What about the quality and price?

Re: Quality is very good. Price is not low but pretty reasonable at this quality level.


Q4. Can you provide samples to test? For free?

Re: Of course, you can take several to test firstly. Your side shall bear the cost due to its high value.


Q5. Can you operate OEM orders?

Re: Yes, OEM is supported though we also have our own brand named AFK.


Q6. What payment methods for chose?

Re: For small order, 100% Paypal, Western Union and T/T in advance. For bulk purchase, 30%T/T, Western Union, L/C as deposit, and 70% balance paid before shipment.


Q7. How about the lead time?

Re: Usually, delivery time is 5-7 working days for sample, 10-15 working days for mass production.


Q8. How will you ship the goods?

Re: For small amount, international express is used mostly such as DHL, FedEx, UPS, TNT. For large amount, by air or by sea. Besides, you also can have your own forwarder pick up the goods and arrange the shipment.
