{"product_id":"smithspecialpurpose3-stagenitrogenlowpressure-16391","title":"Smith Special Purpose 3-Stage Nitrogen Low Pressure - 16391","description":"Description\n\nThis preset three-stage regulator is specially designed to deliver a highly accurate and consistent low-pressure supply of nitrogen to oil-filled power transformers. The regulator will deliver and maintain 0.50 PSIG in the headspace of oil-filled transformers. A built-in self-relieving valve set at 8 PSIG protects the system from over-pressurization due to temperature variation. Both models come with a rapid-fill bypass pressure valve allowing the rapid filling of the transformer with 6 PSIG of pressure.\n\n• This special-purpose regulator is designed to supply constant pressure nitrogen to oil-filled substation power transformers.\n\n• This regulator will maintain oil-filled transformer atmospheres at approximately .5 PSIG.\n\n• This design is constructed with a two-stage preset regulator connected to a highly sensitive single-stage regulator that maintains a .5 PSIG outlet pressure.\n\n• A built-in self-relieving valve set at 8 PSIG protects the system from over-pressurization due to temperature variations.\n\n• This unit is also designed with a purge valve that has a preset pressure of 8 PSIG which is connected to the second stage allowing quick gas filling of transformers.\n\n• This highly reliable design provides constant outlet pressure and flow.\n\n• Adjusting screws are concealed to prevent tampering.","brand":"like appliance","offers":[{"title":"Default Title","offer_id":58763971625344,"sku":"SMI16391","price":453.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/3178\/0480\/files\/SMI237-142958C_2b054863-a8fe-469d-a89b-6138b871609b.jpg?v=1787579443","url":"https:\/\/likeappliances.shop\/products\/smithspecialpurpose3-stagenitrogenlowpressure-16391","provider":" Like Appliances","version":"1.0","type":"link"}
