Gates, valves, and flow control components for agricultural irrigation mainline and surface irrigation systems. From alfalfa valves and hydrants to butterfly valves, check valves, and foot valves - find the right valve for your application here.

  • Alfalfa valves - above-ground shutoff valves for gated pipe and portable equipment connections (Waterman and Fresno compatible)
  • Hydrants - above-ground connection points for supply hoses, big gun carts, and wheel line laterals
  • Butterfly valves - cast iron and in-line butterfly valves for mainline shutoff and flow control
  • Foot valves - aluminum flanged foot valves for pump suction lines - maintains prime and prevents backflow (6", 8", 10")
  • Check valves - prevents backflow in mainline and pump discharge applications
  • Ball valves - compact shutoff valves for smaller line sizes
  • Navigator flow control valves - for precise water management on gated pipe runs
  • Valve openers and stubs - operating tools and connection hardware for alfalfa and surface irrigation valves
