4" Stainless Steel Check Valve with Viton O-Ring - 1000 Series

Why pay more for a no-lead brass valve?! 
BUY - Stainless Steel

• More Strength
• More Corrosion Resistant

Water wells need a check valve installed above the pump between lengths of drop pipe. The NO-SPIN POPPET is very important and the valve must hold the weight and be corrosion resistant. A stainless steel check valve (with no lead) is the answer.

• All parts stainless steel - spring, lock nut on poppet and nut retaining cup locks spring to nut.
• Guide bearing of Delrin® around poppet stem for straight operation and eliminates wear.
• No-Spin Poppet for demanding installation directly above submersible pump.
