The valve uses a diaphragm that is both weight-loaded and spring-loaded, ensuring a firm, positive close on every cycle. Maximum closing time is two seconds. On loss of power, the valve closes automatically, making it suited for final shutoff service. Opening time is field-adjustable using various sized bleed orifices or an adjustable bleed valve. The body is cast aluminum in a straight-through valve pattern. Licensed HVAC technicians and gas-fitting professionals are the primary installers of this valve.\u003c\/p\u003e\n\u003cp\u003eThe v88a1691\/u is rated for use with natural gas, LP gas, and manufactured gas, making it a versatile fit across residential and light commercial heating applications. The 24 VAC control signal aligns with standard low-voltage thermostat and control-board wiring used in forced-air furnaces and similar gas appliances. The straight-through body pattern simplifies in-line installation in gas train piping. A valve position indicator is available as an accessory for installations where visual confirmation of valve status is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.5-inch valve body in a straight-through pattern for direct in-line installation\u003c\/li\u003e\n  \u003cli\u003eDiaphragm is both weight-loaded and spring-loaded for a firm, positive close\u003c\/li\u003e\n  \u003cli\u003eTwo-second maximum closing time for fast shutoff response\u003c\/li\u003e\n  \u003cli\u003eCloses automatically on power failure — suitable for final shutoff service\u003c\/li\u003e\n  \u003cli\u003eField-adjustable opening time via bleed orifice selection or adjustable bleed valve\u003c\/li\u003e\n  \u003cli\u003eCompatible with natural gas, LP gas, and manufactured gas\u003c\/li\u003e\n  \u003cli\u003eCast aluminum body for lightweight, corrosion-resistant construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 24 VAC low-voltage gas-fired heating system service.

Shut off the manual gas supply and de-energize the 24 VAC control circuit before removing the existing valve. Verify gas type, inlet pressure, and flow direction before installing the replacement valve. Leak-test all connections with an approved gas-leak detection solution after installation and before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Size\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Pattern\u003c\/strong\u003e: Straight-through\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClosing Mechanism\u003c\/strong\u003e: Weight-loaded and spring-loaded diaphragm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Closing Time\u003c\/strong\u003e: 2 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Gas Types\u003c\/strong\u003e: Natural gas, LP gas, manufactured gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFail Position\u003c\/strong\u003e: Closes on power failure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: v88a1691\/u\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51467849957682,"sku":"V88A1691\/U","price":746.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/V88-2.jpg?v=1783912743","url":"https:\/\/voomisupply.com\/products\/honeywell-v88a1691-u-1-5-in-diaphragm-gas-valve-24v","provider":"Voomi Supply","version":"1.0","type":"link"}
