FLOW CONTROL with ASEPTIC PROCESS ADAPTATION F
or flow monitoring of aqueous or oily fluids in hygienic applications, EGE presents its new STD flow
controller with an aseptic Varivent F process adapter. The thermal sensor is suitable for use in category 2 hazardous areas. It detects flow velocities between 1cm/s and 10cm/s in water and between 3cm/s and 200cm/s in oil. Depending on the temperature class of the explosive gas mix it is exposed to, it is suitable for ambient temperatures from -20°C to 85°C. The process adapter has an IP67 protection rating and withstands pressures up to
60 bar. The flow controller is connected to the SKZ analysis
device via a PUR cable. EGE has also

launched new screw- in adapters that
enable easy installation of its flow control systems ST 418, SNS, and SCS probes and compact sensors, which can now be simply plugged in, aligned and screwed tight. The adapter is screwed into a T-piece or a welding sleeve. During installation, the plug connector
and the LED display can be freely oriented. After that, the sensor is secured in the adapter using a union nut. The connection is reliably sealed up to 100 bar. Various screw-in adapter models that are optionally available allow for universal use of the flow sensors. Standard versions are supplied with a G¼ or G½ thread. The sensors operate according to the thermodynamic principle and are suitable for monitoring liquid flow rates up to 300cm/s. n

NEW SOLENOID VALVE REGULATES FLOW
subassemblies expert, Magnet Schultz (MSL), has announced the introduction of a new compact proportional solenoid- controlled pneumatic valve range designed for the efficient regulation of air and gas flows across a broad range of applications and industry sectors. Available in 16mm and

pressure-supported open, closed and pressure balanced configuration. The 20mm diameter unit offers pressure supported open and pressure balanced configurations. The compact units handle
The 16mm diameter proportional solenoid pneumatic valve from Magnet Schultz’s latest valve range
20mm diameter variants, the new VPRM solenoid valve allows precise proportional control of air and gas in applications such as air pressure and air volume control in spray-painting equipment, dosing of inert gas in welding, gas regulation in vehicle exhaust systems, gas and oxygen mixing in respirators and
medical equipment, and in fuel cells for building and automotive energy generation, among others. In contrast to the on/off valves typically
deployed in these types of application, the VPRM units deliver the advantage of fully proportional, direct-acting gas flow control. The 16mm diameter unit is available in
16-bar static pressure in the armature space with nominal gas flow rates from 30 to 200 litres per minute. All variants feature fast response times, high linearity and low hysteresis, and a switching service life of 50 million cycles. In standard specification,
VPRM valves operate from a 12V DC supply, with electrical connection via free flexible lead ends. Voltages from 6V to 24V DC, by special order. n
