When a main header valve fails or leaks under pressure, your entire project comes to a standstill while labor costs continue to climb. With summer heat windows tightening and supply chain volatility causing long lead times on heavy iron components, waiting until a valve fails is a risk to your reputation. Securing your inventory of reliable butterfly valves now ensures you avoid back-order delays and keep your crews moving during the high-demand months. Planning ahead provides the relief of knowing your installations will pass inspection and operate without interruption when your clients need water most.\u003c\/p\u003e\u003cp\u003eThe Soval 840 Series Butterfly Valve offers a significant technical advantage over standard gate valves through its compact wafer design and superior flow control. The streamlined profile reduces the physical footprint of your manifold, saving space in tight vaults and reducing the overall weight of the piping assembly. This translates to faster installation times and less physical strain on your crew during assembly. By choosing a high-grade cast iron body with a resilient seat, you minimize long term maintenance costs and prevent the common seizing issues associated with lower-quality alternatives. Maintaining a stock of these valves gives you a competitive edge by allowing for rapid deployment and professional, high-performance results on every site.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eDuctile Cast Iron Body\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValve Style\u003c\/td\u003e\n\u003ctd\u003eWafer Type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e840 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeat Material\u003c\/td\u003e\n\u003ctd\u003eEPDM Resilient Seat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisc Material\u003c\/td\u003e\n\u003ctd\u003ePlated Ductile Iron or Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003e200 PSI Working Pressure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Standard\u003c\/td\u003e\n\u003ctd\u003eCompatible with ANSI 125\/150 Flanges\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperation\u003c\/td\u003e\n\u003ctd\u003eLever Handle with Locking Notch Plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\/Finish\u003c\/td\u003e\n\u003ctd\u003eEpoxy Coated Blue or Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThe 840 Series is available in a comprehensive range of sizes starting from 2 inch diameters up to 12 inch configurations to suit large scale commercial and agricultural headers.

Ensure the disc is in the partially open position during installation to prevent damage to the resilient seat during flange bolt tightening. No gaskets are required for the wafer style as the seat face provides the necessary sealing surface against the flanges. Always follow local plumbing codes and manufacturer torque sequences to ensure a leak free connection and optimal operation of the lever handle.\u003c\/p\u003e","brand":"Soval","offers":[{"title":"2-1\/2\"","offer_id":52327349289249,"sku":"840-025","price":119.99,"currency_code":"USD","in_stock":false},{"title":"2\"","offer_id":52327349322017,"sku":"840-020","price":99.99,"currency_code":"USD","in_stock":false},{"title":"3\"","offer_id":52327349354785,"sku":"840-030","price":139.99,"currency_code":"USD","in_stock":false},{"title":"4\"","offer_id":52327349387553,"sku":"840-040","price":219.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/840_260c5948-e3b1-4e8f-a6d3-15da93a225d0.png?v=1770660893","url":"https:\/\/asiwsupply.com\/products\/840-series-butterfly-valve-cast-iron-body-wafer-style","provider":"ASIW","version":"1.0","type":"link"}
