Poly or Stainless Irrigation Injection Check Valve

Irrigation injection Check Valves prevent backflow, siphoning and bleed through of product. John Blue offers check valves in both poly and 316 stainless steel. We just recently introduced a bleeder valve to compliment your John Blue Irrigation Check Valves. With the added bleeder valve you can bleed air from your distribution lines which can help prime your chemical injection pump.
