{"product_id":"armstrong-gd-45-live-steam-pressure-regulator","title":"Armstrong GD-45 Live Steam Pressure Regulator","description":"\u003cdiv\u003e\u003cp\u003eThe Armstrong GD-45 Direct-Acting Pressure-Reducing Valve is a 1-inch live steam regulator that steps downstream pressure down from an inlet range of 15–300 psi to a controllable setpoint of 3–15 psi, making it suitable for steam lines and non-corrosive gas services. It operates with a minimum differential of 7 psi and is rated for service up to 450°F, enabling reliable regulation in boiler rooms and distribution networks. Built for durability in demanding steam service, the GD-45 features a ductile iron body (ASTM A536), a hardened stainless steel valve seat (AISI 420), and a phosphor bronze bellows (ASTM B103), with a flow coefficient (Cv) of about 2.5 for the 1-inch size; 1\/2\" and 3\/4\" variants are also available to fit different piping layouts. Typical applications include maintaining stable downstream pressure for turbines, condensate-return systems, and other process equipment fed from live steam, where precise pressure control protects equipment and instrumentation. The regulator is part of Armstrong’s GD-45 family of direct-acting pressure-reducing valves designed specifically for steam, air, and non-corrosive gases, offering 1\" nominal connections and a compact footprint that supports retrofit into existing steam headers. \u003c\/p\u003e\u003c\/div\u003e","brand":"Armstrong","offers":[{"title":"New","offer_id":51660111708462,"sku":null,"price":715.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ce0dced9-ba6c-450d-b1e9-34a742c191ab.jpg?v=1769533109","url":"https:\/\/plgautomation.com\/products\/armstrong-gd-45-live-steam-pressure-regulator","provider":"PLG Automation ","version":"1.0","type":"link"}
