The start of a new year always brings an uptick in inquiries at Equilibar. We invite engineers and researchers to check out our product brochures for in-depth information about our innovative fluid control valves and back pressure regulators. See our product literature page or read on for a round-up of our most popular offerings.
Research series:
Equilibar® Research Series back pressure regulators and flow control valves solve critical performance problems for laboratory, gas analysis and other challenging scenarios. They are especially popular for applications such as catalysis research and reservoir core analysis.
Equilibar has several different trim styles and many different diaphragm materials in the Research Series designs. Research Series back pressure regulators and flow control valves work through an incredibly wide range of flow, pressure, and temperature. Materials include Hastelloy, SS316L, PTFE, and FFKM (Kalrez), to name a few.
Maximum temperature ranges are standard 150°C, with the capability to go up to 200°C (with viton seals and metallic diaphragm) and 325°C (with Kalrez seals and metallic diaphragm). In extreme temperature cases, High Temperature (HT) models can be used in processes up to 450°C. They are available in port sizes of 1/16″, 1/8″ and 1/4″ to accommodate most low flow / low dead volume requirements.
Sanitary devices:
The Equilibar® FD Series valves are machined from stainless steel or Hastelloy and are suitable for use in industries such as personal care products, food and beverage and pharmaceutical manufacturing. Equilibar back pressure regulators can be used for pressure control or automated flow control operations.
The Equilibar® SD Series single use back pressure regulators are designed for use in the rapidly expanding single use technology (SUT) field for the biopharmaceutical industry. The disposable SD body and diaphragms are made from USP Class VI polymers and are inserted into a permanent stainless steel support housing with wing nut closure for quick and easy assembly.
Both sanitary valve series feature Equilibar’s patented dome-loaded multiple orifice technology delivering instantaneous control, frictionless operation, superior precision, and exceptionally wide flow rate range . They offer advantages for sanitary fluid control applications in consumer products and biopharmaceutical production such as gradient chromatography, tangential flow filtration, and liquid dosing.
General service:
Equilibar’s GS valves and regulators provide stable pressure control for gases, liquids, and mixed-phase fluids in inlet/outlet port sizes from 1/4″ to 1″. Common materials in stock are SS316L and PVC; depending on application needs, other materials available for order are Hastelloy C276, Titanium, Monel, Zirconium, Aluminum, CPVC, PVDF, PTFE and PEEK.
The GS Series comes in different trims to suit process parameters. A GR trim is more efficient for the lower pressures and NR is more robust for higher pressures.
Common applications for the GS Series include fuel cell testing, continuous API manufacturing, pressure bypass control and high resolution flow control.
Industrial service:
Equilibar’s BD Series back pressure valves with pipe sizes from 1.5″ up through 4″ handle higher flow applications. The BD Series has external elbows attached to the bottom to save significant space compared to side-ported cylindrical designs. Stainless steel and aluminum valve bodies are welded to commercial pipe elbows, while PVC valves are glued to commercial elbows. If desired, flanges can be welded to the elbows as an option. Aluminum elbows are square in shape while stainless steel and PVC are rounded.
BD valves are used for gases, liquids, and mixed phase applications. For liquid applications, an application engineer will discuss the downstream piping design to make sure that water hammer (resonance) does not cause an issue.
Vacuum controllers:
Like our unique back pressure regulator technology, the Equilibar® vacuum regulator (EVR) uses multiple orifices sealed by a flexible diaphragm instead of a single large valve seat and is dome-loaded by a pilot regulator setting the vacuum setpoint. As flow requirements change, the diaphragm moves a few millimeters to open and close over some or all of the orifices, providing instantaneous and frictionless control. The pilot setpoint pressure may be set with a manual or electronic vacuum pilot regulator.
EVR is available from 1/4″ to 4″ port sizes. Starting at $600, they offer a good option for complex vacuum applications where conventional solutions have not worked.
Additional offerings:
Equilibar also offers electronic regulators and many styles of pressure reducing regulators. Specialty devices include supercritical valves, Mity Mite replacement valves and others. For more information please contact one of our application engineers. They are excited to work on new projects for 2021!
