Cryogenic Globe Valves

Our selection of cryogenic globe valves are available in manual, pneumatic and electric actuation types and can be used for on/off (shut off), flow regulating or control purposes. We can offer valves in straight-through or angle pattern configurations, from sizes DN2 to DN300, all available with a huge range of additional accessories including solenoid valves, limit switches, welding flanges, IP Positioners and more.

Our cryogenic globe valves can be made suitable for installation in any position, including in vacuum jacketed lines (VJ lines) or super insulated vacuum lines (SIVL). All valve bodies are machined from one singular piece of barstock 316L stainless steel (or specialty alloy) and comprise of a precision-engineering bellows seal for ultra-high leak integrity.

Electromagnetic Flow Meters

The MIM electromagnetic flowmeter was developed as a complete solution for measuring and monitoring small to medium flow rates of conductive liquids in systems. This flow meter operates based on the electromagnetic measurement principle (also referred to as magnetic inductive).MIM Electromagnetic Flow Meters

According to Faraday’s Law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field. The electrically conductive measuring agent acts as a moving conductor. The voltage induced is proportional to the flow velocity and is therefore a value for the volumetric flow rate.

For the flow meter to function correctly, the flowing media must have a minimum conductivity of ≥ 20 µS/cm. The induced voltage is picked up by the two sensing electrodes which are in contact with the measuring agent and sent to the measuring amplifier. The flow rate will then be calculated based on the cross-sectional area of the pipe. A key advantage of this operating principle is that the flow measurement is not dependant on the process liquid and its material properties such as density, viscosity and temperature. Typically, with an electromagnetic flow meter there are no moving parts in the measuring device and this can be a critical benefit to many industrial applications.

Pressure Sensors for Refrigeration Systems

Due to the worldwide rising energy costs, the energy-efficient operation of refrigeration systems becomes a ‘must’ for all installers, integrators and contractors working in this field. According to estimates from third-party sources, more than 90% of the refrigeration systems worldwide are still not yet equipped with continuous control technologies.

Most of these systems have been optimised and pre-set for certain operating states and refrigeration capacity – which means that they operate outside the ‘optimum’ in all other operating states, whenever less capacity is required. This will often result in a waste of valuable energy. At a point soon, systems without any closed-loop control will no longer be acceptable within the industry.

Therefore, manufacturers and integrators of refrigeration systems are increasingly looking to utilise electronic pressure sensors to control pressure and thus the resulting temperature of the refrigerant with high precision. Our R-1 pressure sensor has been developed specifically for this use and in practice achieves substantial savings in electricity costs for the operators.
