The UK’s leading authority on electric actuators and solenoid subassemblies, Magnet Schultz Ltd (MSL), is highlighting the availability of its compact proportional solenoid-controlled pneumatic valve range designed for the efficient regulation of air flows in medical ventilators as well as gas flow regulation across a broad range of other applications and industry sectors.Available in 16mm and 20mm diameter variants, the compact VPRM solenoid valve allows precise proportional control of air, and the mixing of air and gas, in respirators and medical equipment. The 16mm model is already being used in paediatric ventilators, where the advantages of fully proportional, direct-acting air flow control are ideally suited to the critical and delicate application.
As well as ventilators and medical respiratory equipment, the VPRM units are ideal for heavier duty air flow applications such as air pressure and air volume control in spray painting equipment. In addition, the valves can be used with other gases, opening up precise promotional control options rather than a typical on/off function in applications that include dosing of inert gas in welding, gas regulation in vehicle exhaust systems, and in fuel cells for building and automotive energy generation, among others.
The 16mm diameter VPRM unit is available in pressure supported open, closed and pressure balanced configuration. The 20mm diameter VPRM unit offers pressure supported open and pressure balanced configurations.
The compact VPRM units handle 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. The standard specification VPRM valves in stock at Magnet Schultz Ltd operate from a 12V DC supply,with voltages from 6V to 24V DC also available.
