{"title":"2-Way Vacuum Solenoid Valves","description":"\u003cp\u003eDirect and semi-direct operated solenoid valves operate from a zero bar pressure differential, therefore they are suited for most vacuum applications. For (ultra) high vacuum, special valves are on the market with a very low leakage rate, standard solenoid valves are not appropriate in this case. Directly operated solenoid valves have a small orifice, but they are reliable and have good sealing properties. Semi-direct operated valves have an internal flexible membrane and are characterized by a higher flow rate. With a very light vacuum, the sealing properties may be somewhat less compared to a direct acting valve. The direction of flow in a valve is often indicated on the housing with an arrow, or with a 1 or IN for the inlet port, and a 2 or OUT for the outlet port. Connect the vacuum to the outlet port (ie, port 2 or OUT), so that the direction of flow is always from the inlet to the outlet port. The article Solenoid valves for vacuum provides more background information.\u003c\/p\u003e","products":[{"product_id":"nls-018-g1-8inch-stainless-steel-needle-valve-ptfe-300-bar","title":"G1\/8'' Stainless steel Needle Valve PTFE 300 bar - NLS","description":"\u003cp\u003eVery compact stainless steel needle valve with G 1\/8\" threads. This valve can be used as a reliable shut-off valve, or to accurately control (relative low) flow rates of clean gases or fluids. The valve has a nominal internal diameter of 2.5 mm. The seals are made of PTFE. The max pressure is 300 bar and the allowable temperature range is from -20 to max. 200°C. Thanks to the high quality materials and robust construction, the valve is suited for high pressures and agressive fluids.\u003c\/p\u003e","brand":"Tameson","offers":[{"title":"Default Title","offer_id":46756659003721,"sku":"NLS-018","price":28.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/1787\/6152\/files\/nls-012-1.414381c2_ca236438-60ca-4a0b-a29e-1804e5e2820f.jpg?v=1727935996"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/1787\/6152\/collections\/st-da-magneetventiel-messing-014inch-01.890d387f_f0a01a2c-9445-4f60-8b48-74e464e4b094.jpg?v=1774544892","url":"https:\/\/tamisoon.com\/collections\/2-way-vacuum-solenoid-valves.oembed","provider":"tamisoon.com","version":"1.0","type":"link"}
