In the early 50s, Marotta offered its first high-pressure liquid and gas solenoid valves.","categories":["MANUFACTURER","SERVICE_PROVIDER"],"employeeCountRange":"FROM_251_TO_500","foundingYear":1943,"digitalPresence":{"linkedinUrl":"https://www.linkedin.com/company/marotta-controls","facebookUrl":"https://www.facebook.com/MarottaControls/","twitterUrl":"https://twitter.com/MarottaControls/","crunchbaseUrl":"https://www.crunchbase.com/organization/marotta-controls","dnbUrl":"https://www.dnb.com/business-directory/company-profiles.marotta_controls_inc.4beba8ecca30bc17d529717c4ca2a163.html"},"keywords":["Aerospace","Consumer","Navigational, Measuring, Electromedical, and Control Instruments Manufacturing","Consumer Goods","Other Fabricated Metal Product Manufacturing","Valves and pipe fittings, Process control instruments","Consumer Electronics","Marine Technology","Fabricated Metal Product Manufacturing","Manufacturing","Electronics"],"websiteUrl":{"entry":"https://marotta.com/","target":"https://marotta.com/"},"logo":{"internalName":"27bbcf24a179d493b6928aa665c02f_1648280759.jpg","name":"27bbcf24a179d493b6928aa665c02f_1648280759.jpg","url":"https://api.platform-production.ensun.io/file/external-company-logo/649e646803f8bf35153ee88e"},"certifications":[],"location":{"_id":"64b66c095cca02372672bdc0","city":"Montville Township","state":"New Jersey","country":"United States","countryCode":"US"},"industries":[{"_id":"60dc4354637b44ca344b2cb9","name":"Consumer Electronics"},{"_id":"60dc4354637b44ca344b2cbe","name":"Hardware"},{"_id":"60dc4354637b44ca344b2cb4","name":"Science and Engineering"},{"_id":"61d5f4200864ec4168981964","name":"Others"},{"_id":"60dc435c637b44ca344b2cda","name":"Consumer Goods"},{"_id":"60dc4354637b44ca344b2cbf","name":"Manufacturing"}]}},{"page":{"__typename":"CrawledPage","_id":"64a1fe7d9d1a9bdff4313530","url":{"entry":"https://www.physikinstrumente.co.uk/en/products/piezoelectric-transducers-actuators/stack-actuators","target":"https://www.physikinstrumente.co.uk/en/products/piezoelectric-transducers-actuators/stack-actuators"},"content":[{"type":"p","text":"PICA piezoelectric linear actuators in stacked design are very reliable and feature a large specific displacement.
