INSTRUM pressure regulators – The Original!

We apply pressure … in tanks, reactors, vessels, centrifuges and continuous agitated reactors in the process engineering industry.

INSTRUM is working successfully world-wide for more than 30 years in the development, construction and manufacturing of pressure regulators for tank blanketing and inerting. INSTRUM pressure regulators can be generally used in liquids and gases, particularly in corrosion-proof applications.

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.

INSTRUM® Low pressure regulators and relief valves

Inertization process

One important part in the product range is the low pressure regulators. They have typically big diaphragms …

Tank Blanketing system

Overpressure and Vacuum protection in tanks and tank storage

One understands the combinations of valves under the Tank blanketing system, which are used especially for langer tanks and tank storage to protect against unacceptable pressure and vacumm situations and also inertiate if necessary.The structural protection against impermissible overpressure or vacuum in these cases usually implemented with weight-loaded valve systems, s.a. Overpressure and Vacuum protection.

System for Sterile Applications

Safe Sterlisation Instrum® Stainless Steel Pressure Regulator

When blanketing in sterile areas further design features are required in addition to the high, electropolished surface quality and the materials required especially for the food and pharmaceutical industries. INSTRUM® stainless steel pressure regulators offer GMP-compliant design to minimize or eliminate germinated zones.

Precision Pressure regulator for liquids

Pressure reducing and excess pressure valve

Our precision pressure regulators for liquids are especially characterised by the fact that they fulfill application-specific requirements with regard to highest control quality with compact size and admission pressure independency.

Safe Sterlisation Instrum® Stainless Steel Pressure Regulator

Balancing and adjusting fluctutating pressure

Precision pressure regulators for corrosive media are mainly used where fluctuating pressures need to be equalized. A diaphragm is used to measure the pressure and compare it with the set point. The resulting forces are used to continuously and automatically readjust the seat of the valve.
