It features a rising stem and barstock body with a non‑rotating stem to reduce wear on the stem and seat, and it uses a 0.187 in (4.75 mm) orifice with a flow coefficient (Cv) of about 0.65 for predictable throttling. Standard packing is PTFE and rated up to 450°F (232°C); higher‑temperature options TG (to 600°F\/316°C) and GY (to 650°F\/343°C) are available for elevated service temperatures. The SW4071 is part of Parker Autoclave Engineers’ SW Series Low Pressure Valves, with tubing engagement options described for 1\/4 in to 1\/2 in tubing and a 2‑way straight configuration suitable for precise gas or liquid control in demanding environments. Typical applications span chemical and petrochemical processing, laboratory research, and oil and gas fluid handling where reliable, bubble‑tight shutoff and smooth metering at high pressure are essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"Autoclave","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660355633454,"sku":null,"price":5068.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2cf0010e-57a1-438b-99b3-7b66f5b8bcd7.jpg?v=1769536672","url":"https:\/\/plgautomation.com\/products\/autoclave-engineers-sw4071-low-pressure-needle-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
