This model combines a Lite-Rite manual gas cock, Pilotstat safety shutoff, millivoltage-operated automatic valve, and adjustable pressure regulator into one control unit. It functions without external electrical power, drawing energy from a thermopile generator heated by the pilot flame. Designed for flexibility, it mounts in any position up to 90° from vertical and includes multiple tapped ports for convenient piping. The valve is UL and CSA certified for reliability and safety compliance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSelf-Powered Operation: Works with a 750 mV PowerPile generator, eliminating external electrical power requirements.\u003c\/li\u003e\n\u003cli\u003eIntegrated Safety Design: Combines manual gas cock, automatic valve, and Pilotstat safety shutoff in one assembly.\u003c\/li\u003e\n\u003cli\u003eComplete Flame Failure Protection: Shuts off main and pilot gas flow immediately upon pilot flame loss.\u003c\/li\u003e\n\u003cli\u003eAdjustable Pressure Regulator: Factory set to 3.5 in. wc with adjustable range of 3–5 in. wc for consistent performance.\u003c\/li\u003e\n\u003cli\u003eLITE-RITE Lighting Sequence: Features OFF-PILOT-ON positions for simplified startup and reliable ignition.\u003c\/li\u003e\n\u003cli\u003eUniversal Mounting Capability: Installs in any orientation within 0–90° of vertical, accommodating various system layouts.\u003c\/li\u003e\n\u003cli\u003eService-Friendly Construction: All adjustments and terminals accessible from the top of the control for easy setup and maintenance.\u003c\/li\u003e\n\u003cli\u003eDurable Straight-Through Body: Cast metal housing with 3\/4″ NPT inlets\/outlets and 1\/2″ NPT side taps ensures long service life.\u003c\/li\u003e\n\u003cli\u003ePilot Flow Adjustment: Built-in screw provides fine control for pilot flame tuning.\u003c\/li\u003e\n\u003cli\u003eComprehensive Certification: UL Component Recognized, CSA and AGA Design Certified for safety and performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe VS820A1054 delivers the dependable performance, safety, and convenience required for self-powered natural gas heating systems.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49105122689280,"sku":"VS820A1054","price":1095.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/shopping_5_ec7f4a4d-dd17-48d1-a5d6-66ec3e2bd9de.webp?v=1785540749","url":"https:\/\/alotechparts.com\/products\/vs820a1054-honeywell-powerpile-millivolt-combination-gas-valve-34-npt-for-natural-gas","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
