Video Shows Electronic Back Pressure Control Controlling back pressure with an electronic signal is easily achieved by combining an Equilibar pilot operated back pressure control valve with an electronic air pressure regulator. This short video shows an Equilibar LF ‘low flow’ series back pressure regulator being pilot operated by a 0 to 1000psi command pressure. Click Read More

Equilibar’s line of high accuracy and high flow vacuum regulators have been available only in stainless steel 316 or in PVC plastic. Now Equilibar is offering it’s vacuum regulator designs in durable and lightweight anodized aluminum. This aluminum construction offers lower cost than stainless and superior durability over the previous PVC models. Aluminum Vacuum Regulators Offer Read More

We’re pleased to announce that we’re expanding to more than doubled our workspace. Things are a bit of a mess right now as we transition into our new workspace but we are excited because all of this extra room means more space for more products and more research!

Equilibar’s pressure control offerings have expanded rapidly over the past few years. As a result, we’ve outgrown our original part numbering system and have transitioned to a more flexible, user-friendly part numbering system. We have always offered products in a nearly unlimited number of configurations. Each of our back pressure regulators can be made from Read More

Researchers at the Technical University of Delft in The Netherlands are exploring a novel method of using Carbonated Water Flooding to increase the amount of oil that can be recovered from sandstone reservoirs and to improve the environmental impact and safety of the oil extraction process. As part of this endeavor, they used an Equilibar® back pressure regulator that is Read More

The Institute of Chemical Technology at Germany’s University of Stuttgart is leading research efforts to find improved catalysts for the production of phthalic anhydride, a primary precursor for the production of plasticizers. Previous research in this area has been limited by the need to maintain an extremely low concentration of the o-xylene reactant (<1%) in the catalytic reactor to avoid hot Read More

Equilibar announces its new patent-pending BR1 Blockage Resistance Series aimed at supercritical applications such as CO2 extraction. The video linked below shows how the new design expels ice and resists blockage, even at high flow rates with Joules Thompson cooling effects. During the buildup and expulsion of ice, the pressure is maintained in a very Read More

We are pleased to announce that Equilibar now offers direct replacements for select models of Mity Mite back pressure regulators. Mity Mite regulators were first manufactured by Grove Valve and Regulator Company in the 1960s and soon became the standard for many specialty applications. The Pressure Reducing Mity Mite regulators were quite common in experimental Read More

Equilibar’s proven and patented multi-orifice technolgy is now available in bigger packages! Introducing the HV series back pressure and vacuum valves. These valves are ideal for applications requiring small differential pressures and/or high flow rates. The unique inlet orifice arcs reduce inlet friction to provide the user with maximum control and stability. The HV series regulators Read More
