Designed for heavy-duty commercial HVAC applications, this high-performance valve integrates three essential functions—a shut-off valve, a non-slam check valve, and a calibrated balance valve—into a single, compact body to simplify piping and installation.\u003c\/p\u003e\u003cp\u003eThe 3DS-8B mechanism utilizes a precision-engineered disc and spring assembly that provides bubble-tight shut-off while preventing water hammer and backflow. By combining these critical functions, the valve allows for efficient system balancing, maintenance isolation, and flow modulation without the need for additional individual components, reducing total pressure drop across your hydronic circuit.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eFlow Control:\u003c\/b\u003e Integrated balancing features allow for precise adjustment of system flow rates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNon-Slam Operation:\u003c\/b\u003e The internal spring-loaded check mechanism eliminates noise and damaging pressure surges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSystem Isolation:\u003c\/b\u003e Provides reliable bubble-tight shut-off for streamlined maintenance and service.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePressure Efficiency:\u003c\/b\u003e Optimized internal geometry significantly reduces turbulence and total head loss.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial hot and chilled water systems, high-rise building risers, and primary pump discharge applications where space-saving multi-function valve performance is required.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43125812461662,"sku":"132164","price":5820.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/132164_image_453a235f-0659-45ec-a2b3-aa4e381bc2b6.png?v=1786037813","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-132164-3ds-8b-8-triple-duty-valve","provider":"National Boiler Supply","version":"1.0","type":"link"}
