日本スターテクノ Product Lineup

Our representative technology is the dome-shaped porous backpressure regulator, and we offer models that accommodate a wide range of Cv values, maximum pressures, and temperatures. Equilibar also has a rich product lineup, including electronic regulators, pressure-reducing regulators, special valves and regulators, and vacuum regulators, providing optimal solutions for even the most complex situations.

We solve critical performance issues for laboratories and gas analysis systems around the world. They are particularly popular in applications such as catalyst research and reservoir core analysis. Equilibar features a design in the Research Series with multiple trim styles and a variety of diaphragm materials, accommodating many demanding research environments. The back pressure regulators in the Research Series handle a very wide range of flow rates, pressures, and temperatures. Materials include Hastelloy, SS316L, PTFE, and FFKM (Kalrez). The maximum temperature range for research back pressure regulators is standard at 150°C, with a maximum of 200°C using Viton seals and metal diaphragms, and up to 325°C with Kalrez seals and metal diaphragms. For extreme temperatures, the High-Temperature (HT) model can be used in processes up to 450°C.

Designed for pilot scale and manufacturing scale, these models are widely used for electrolysis, fuel cell testing, continuous API manufacturing, pressure bypass control, and high-resolution flow control. Trim and body materials can be customized to meet process requirements. Common stock materials include SS316L and PVC, but depending on the application, GS backpressure regulators can also be made from materials such as aluminum, Hastelloy C276, Monel, PTFE, and PEEK. O-ring and diaphragm materials are also available in various materials to suit process needs.

Equilibar offers two form factors within this size range: the IC Industrial Collection and the BD Series, each with its own unique advantages. The optimal choice depends on the application requirements, so please consult with our application engineers regarding that. Both models are designed with Equilibar's dome-loaded porous technology, enabling precise control across a wide flow range. Port sizes are available as standard from 1.5 inches to 4 inches, with custom sizes available upon request.

By upgrading to an SS316 diaphragm and Kalrez O-ring, the operating temperature range can be extended to 300°C/527°F. Using a metal diaphragm also allows the pressure range to be increased to a maximum of 10,000 psig/689 bar(g). The standard PTFE/glass composite diaphragm can be used under conditions of low pressure up to 232°C (450°F), but considering the mechanical stress reduction of PTFE at high temperatures, the SS316 diaphragm is more practical for most high-temperature applications. In some applications, diaphragms made of Hastelloy C276 are also available.

It demonstrates high precision performance in high-pressure applications up to 10,000 psig / 689 bar(g). Equilibar's high-pressure regulators are available in standard low-flow models for applications such as high-pressure reactors and ultra-low-flow models for applications like high-pressure core testing. They achieve high precision and stable control for liquid, gas, and multiphase fluids. Equilibar has announced the U20L, a new ultra-low-flow BPR with a rated pressure of 20,000 psig / 1375 bar(g), integrated into DCI Test Systems' ABPR-20. The BPR shown on the right, H10P, has a rated pressure of 10,000 psig / 689 bar(g). Since Equilibar regulators are dome-loaded, the dome reference port requires a pilot setting reference pressure equal to the desired inlet pressure (at a 1:1 ratio). This pilot setting pressure is typically supplied from a high-pressure inert gas cylinder, such as nitrogen. Customers usually control this reference setting pressure using a manual pressure-reducing regulator, but there are other methods to apply pressure load to the dome of the Equilibar BPR.

The BR series back pressure regulators with block resistance. This series is particularly ideal for specialized applications such as supercritical CO2 (SCO2) extraction, but is also useful in any process where clogging, blockage, or freezing may occur. This series integrates unique design features that allow customers to achieve precise control by reducing the Joule-Thomson effect as supercritical process fluids pass through the unit. The main design feature of this regulator series is a downstream expansion cavity that continuously increases the cross-sectional area to eliminate convergence points caused by ice accumulation. Furthermore, this large thermal capacity increases the heat transfer area for heating the discharge fluid in multiple ways. Finally, this series has specially designed O-ring grooves to reduce stress during rapid depressurization, extending the lifespan of the O-rings. This series offers several custom fitting options, including outlet flanges, tube stubs, or NPT fittings.

The Mighty Mite back pressure regulator, first released by Globe Company in the 1960s, has been a staple product used in a wide range of fluid control applications, from amateur rocketry to petrochemical research. However, in recent years, many customers in the field of chemical research have reported issues regarding the supply and service of these products. By 2015, customers were faced with the situation of these products being completely withdrawn from the market. If you are looking for a product that can be replaced with exactly the same shape as existing equipment, Equilibar's replacement diaphragms and BPRs (back pressure regulators) will meet your needs. We offer three models with different Cv values and pressure ranges.
