INSTRUM pressure regulators – The Original!

In vessels, reactors, centrifuges or stirred vessels in the process industry, liquids are often blanketed with an inert gas atmosphere to prevent oxidation or contamination or to ensure explosion protection.

Depending on the application and requirements, various regulators in corrosion-resistant materials are used for pressures from 1 mbar to 20 bar. These are mainly self-acting mechanical regulators that operate independently of auxiliary energy, such as pressure regulators for reduction, excess pressure, differential pressure and negative pressure, as well as breather vents for positive and negative pressure.

We offer suitable regulators made of corrosion-resistant materials for blanketing of liquids with an inert gas atmosphere. We design and build systems for tank blanketing, inerting, product transfer and sterilization, with particular focus on self actuated mechanical regulators which work without auxiliary power. These include pressure regulators for reduction, relief, negative and differential pressure, check valves for positive and negative pressure. The INSTRUM approach enables you to reduce significantly your installation and running costs while increasing operational reliability.

The high-quality and technically sophisticated systems for tank blanketing, inerting, product conveying, and sterilization allow a reduction in installation and operating costs with improved operational reliability. The environmental impact is significantly reduced.

INSTRUM® regulators are mainly used for inerting in process-related vessels and containers of typically up to 100 m³ volume. They are often also used in pharmaceutical and biotechnological plants where special approvals such as ATEX, surface finish, FDA etc. but also special design features such as CIP and SIP are required.

Valve Concepts valves are used for both tank ventilation and inerting on vessels of any size. The pilot operated systems in particular have extremely high control accuracy. This allows the smallest overpressures with very low hysteresis effects to be realized at the highest possible throughput.
