14 PUMPSValve expansionFor several years now, the processingindustry has been increasingly lookingfor alternatives to pneumatic actuators.Electric valves are an option. These haveparticular appeal on account of their costefficiency and performance. The reduced riskof contamination and the application in a widevariety of plants are also positives in favour ofelectrically operated valves. The valvemanufacturer GEMÜ is responding to thesecustomer requirements by further expandingits selection of motorized valves with thelaunch of the GEMÜ eSyLite, eSyStep andeSyDrive valves.A low-cost plastic diaphragm valve forsimple and cost-sensitive applications isavailable in the form of the GEMÜ R629eSyLite. It constitutes a cost-effectivealternative to solenoid valves made of plasticor motorized plastic ball valves.The GEMÜ eSyStep valves are designed forstandard open/close and simple controlapplications. With regard to the actuator, thisis a compact spindle actuator with step motor.Via the interface in the housing cover, thevalve can be extended with additionalaccessories such as diverse electrical positionindicators or travel sensors to provide extrafunctions. GEMÜ eSyStep valves are availablein globe valve, angle seat globe valve anddiaphragm valve versions made of metal andplastic but adapting to M-block valves is alsopossible.The GEMÜ eSyDrive valves are availablefor variable and complex open/close andcontrol applications in conjunction with highrequirements on performance and service life.The actuator is based on the hollow shaftprinciple. Both the ethernet-based eSy-webinterface, in conjunction with an integratedweb server, and the Modbus-TCPcommunication interface, enable the exchangeof parametrization and diagnostics data andthe networking of several devices. If necessary,users can also benefit from a range ofintegrated functions such as stroke limitersand speed settings.This provides customers with a wideproduct range of electric valves both forindustrial processes and for applications withparticularly high purity and hygienerequirements. With the different GEMÜeSyLite, eSyStep and eSyDrive ranges, valvesolutions are available for every price andfunction segment.Finishing - January/February 2020
