WOFLY Dual Regulator R31 and Single Regulator R41 Pressure Regulators: Precise Pressure Control, Building a "Safety Line" for High-End Gas Applications

In the transmission and application of high-purity gases and special gases, pressure regulators are key components to ensure system pressure stability and safeguard equipment and personnel. Among them, Singlepressure regulators and Dual pressure regulators, like "twin stars of pressure regulation", play irreplaceable roles in different links. The R31 Dual pressure regulator and R41 Singlepressure regulator launched by Shenzhen Wofly Technology Co., Ltd. WOFLY have become "sharp tools for pressure control" in many high-end fields due to their exquisite craftsmanship and precise performance.

1. Single and Dual Pressure Regulators: The "Golden Partner" of Pressure Regulation

(1) Core Functions

•Single Stage Pressure Regulator: It is directly connected to the gas source (such as high-pressure gas cylinders, gas manifolds), undertaking the task of "preliminary pressure reduction". It reduces high-pressure gas (usually several thousand psig) to a relatively moderate pressure range (such as several hundred to one thousand psig), providing the "first pressure buffer" for downstream equipment.

•Dual Stage Pressure Regulator: On the basis of the Single pressure regulator, it further precisely adjusts the pressure to the low pressure required by the terminal equipment (usually tens to hundreds of psig), realizing "fine pressure control" and ensuring the stability and accuracy of pressure during experiments and production processes.

(2) Key Differences

Dimension SinglePressure Regulator (Taking R41 as an Example) Dual Pressure Regulator (Taking R31 as an Example)

Pressure Reduction Structure Piston-type pressure reduction structure Double-stage diaphragm-type pressure reduction structure

Pressure Accuracy Focuses on "rough adjustment" to ensure the stability of the downstream pressure range Focuses on "fine adjustment" to achieve high-precision pressure control

Application Position Downstream of the gas source, supplying pressure for the Dual pressure regulator Upstream of terminal equipment, directly supplying gas to the equipment

Pressure Resistance Suitable for higher inlet pressure (e.g., 6000psig) Relatively moderate inlet pressure (e.g., 3000psig)

2. WOFLY R41 SinglePressure Regulator: The "Stability Pioneer" for High-Pressure Gas Sources

The R41 Singlepressure regulator of Shenzhen Wofly Technology adopts a piston-type pressure reduction structure, designed specifically for the scenario of "high-pressure input and stable output", and serves as a "pressure bridge" between high-pressure gas sources and downstream systems.

(1) Product Highlights

• Structure and Material: The main body is made of 316L stainless steel or brass. It has a built-in 316L (10μm) filter, and the valve seat is made of PCTFE material, ensuring corrosion resistance and cleanliness in high-purity gas and corrosive gas environments. With a weight of only 0.8kg, it takes into account both strength and portability.

• Performance Parameters: The maximum inlet pressure can reach 3000 and 6000psig, and the outlet pressure range covers multiple ranges such as 0~250 and 0~500. The operating temperature is -10~165℉ (-23~74℃), and the leakage rate reaches the "bubble-tight testing" level. The Cv value is 0.06, and it can still supply gas stably under high-pressure working conditions.

(2) Typical Application Scenarios

With its high-pressure adaptability and stable output capability, R41 is widely used in:

• Laboratory Gas Analysis: It provides "first-level pressure regulation" for analytical equipment such as gas chromatographs and mass spectrometers, ensuring the stability of carrier gas and reaction gas pressure and guaranteeing the accuracy of analysis results.

• Process Control: In the high-purity gas transmission process of semiconductors and microelectronics, it provides pressure support for gas mixing and purification links, avoiding the interference of high-pressure fluctuations on precision processes.

• Gas Manifold System: As the "pressure hub" of the multi-cylinder centralized gas supply system, it uniformly reduces the pressure of high-pressure gas sources and supplies gas for subsequent Dual pressure regulators or terminal equipment.

3. WOFLY R31 Dual Pressure Regulator: The "Pressure Control Expert" for Precision Gas Use

The R31 Dual pressure regulator adopts a double-stage diaphragm-type pressure reduction structure, which is the guarantor of "pressure accuracy" for terminal equipment, especially suitable for scenarios with strict requirements for pressure stability.

(1) Product Highlights

• Design and Material: Five-stage valve body design + metal-to-metal diaphragm sealing, realizing "double-stage pressure reduction + fine sealing". Core components such as the main body, diaphragm, and spring are made of 316L stainless steel. It has a built-in filter element, supports panel or wall mounting, and can be optionally equipped with needle valves and diaphragm valves as outlet valves, adapting to diverse installation and use requirements.

• Performance Parameters: The maximum inlet pressure is 3000 and 5000psig, and the outlet pressure accuracy can reach subdivided ranges such as 0~25 and 0~50. The operating temperature is -40~165℉ (-40~74℃), and the helium leakage rate is ≤2×10⁻⁹ atm cc/sec He. It can still maintain extremely low leakage in high-purity and corrosive gas environments. The Cv value is 0.06, and the weight is 1.4kg, taking into account both accuracy and reliability.

(2) Typical Application Scenarios

The high-precision pressure control capability of R31 makes it a "standard configuration" in the following fields:

• Gas Chromatography (GC) and Gas Lasers: It provides "precise" pressure control for chromatographic column carrier gas and laser generating gas, ensuring the stability of separation effect and laser power.

• Testing Equipment: In the airtightness and pressure resistance tests of auto parts and aerospace components, it precisely adjusts the pressure of test gas to ensure the authenticity and repeatability of test data.

• Petrochemical Industry: In fine chemical links such as catalytic reaction and gas purification, it provides stable pressure for reaction gas and protective gas, helping to optimize processes and improve product quality.

4. Wofly Technology: Leading the Pressure Regulator Track with Technological Innovation

Shenzhen Wofly Technology Co., Ltd. has been deeply involved in the field of gas pipelines and control equipment for many years. The R31 and R41 pressure regulators are a concentrated embodiment of its "precise pressure control" technology. Through material upgrading, structural optimization, and process innovation, the two products solve the pain points of traditional pressure regulators such as "insufficient pressure resistance, high leakage rate, and lack of accuracy", providing a reliable solution for the safe and efficient application of high-purity gases and special gases.

From trace gas analysis in laboratories, gas supply in Class 100 clean rooms of semiconductor factories, to harsh working conditions in the petrochemical industry, Wofly R31 and R41 pressure regulators, with the cooperation mode of "Singlerough adjustment to stabilize the gas source and Dual fine adjustment to ensure accuracy", have become a strong backing for "gas pressure control" in various industries. In the future, as the requirements for gas purity and pressure control in fields such as new energy and biomedicine are further improved, Wofly Technology's pressure regulator products are expected to demonstrate value in more high-end scenarios and contribute to the "intelligent gas control" of China's high-end manufacturing industry.
