{"title":"Válvulas De Bola De Latón Neumáticas","description":"\u003cp\u003eExplore Tameson's wide range of 2-way pneumatic brass ball valves from leading global manufacturers. These valves control the flow of media - liquids or gases - using a rotating ball with a bore. A pneumatic actuator connects to the valve and converts compressed air into mechanical motion, rotating the ball 90° (a quarter turn) to open or close the valve. A pneumatic actuator is either single-acting or double-acting; single-acting actuators, also known as fail-safe, use a spring to return the valve to its normal position if air pressure is lost. For larger valves, pneumatic actuation is often more cost-effective than electric actuation.\u003c\/p\u003e\u003cp\u003eA 2-way pneumatic ball valve has two ports - an inlet and an outlet - and a ball with a bore. Because the actuator rotates the ball 90°, these valves are also called quarter-turn, on\/off, or shut-off valves. When the valve is open, media flows from the inlet, through the bore, to the outlet. When the valve is closed, flow is blocked. They're commonly used to remotely control fluid flow, such as in water lines or compressed air systems.\u003c\/p\u003e\u003cp\u003eBrass is a copper-zinc alloy known for its strength and resistance to contaminated media, making it a reliable, low-maintenance choice for most non-aggressive media like water, gas, oils, and compressed air. However, brass is not suitable for salt water or distilled water, as it can suffer from dezincification, a process that weakens the material over time.\u003c\/p\u003e","products":[{"product_id":"g1-8-valvula-de-aguja-de-acero-inoxidable-ptfe-300-bar-nls-nls-018","title":"G1\/8'' Válvula de aguja de acero inoxidable PTFE 300 bar - NLS","description":"\u003cp\u003eVálvula de aguja de acero inoxidable muy compacta con rosca G 1\/8\". Esta válvula puede utilizarse como válvula de cierre fiable o para controlar con precisión los caudales (relativamente bajos) de gases o fluidos limpios. La válvula tiene un diámetro interior nominal de 2,5 mm. Las juntas son de PTFE. La presión máxima es de 300 bares y el rango de temperatura permitido es de -20 a máx. 200°C. Gracias a la alta calidad de los materiales y a la robustez de su construcción, la válvula es adecuada para altas presiones y fluidos agresivos.\u003c\/p\u003e","brand":"Tameson","offers":[{"title":"Default Title","offer_id":46641958289747,"sku":"NLS-018","price":28.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0599\/4830\/2533\/files\/nls-012-1.414381c2.jpg?v=1727936064"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0599\/4830\/2533\/collections\/7300.64b232ef_d4feea95-2f3f-4248-b8ec-13597660af95.jpg?v=1774544262","url":"https:\/\/tameson-es.myshopify.com\/collections\/valvulas-de-bola-de-laton-neumaticas.oembed","provider":"Tameson.es","version":"1.0","type":"link"}
