The Griswold 2230H is a heavy-duty, normally closed pressure reducing valve designed for irrigation master-valve and remote-control applications. Built for reliable field performance, it provides accurate pressure regulation across varied terrain and is serviceable without removing the valve body.

  • Operating range: 3 to 200 PSI working pressure; regulating range 5 to 125 PSI for stable downstream pressure.
  • Construction: Cast iron body with bronze internal components and stainless-steel guided diaphragm-disc for long service life.
  • Connection size: 1 in. FIPT (female pipe thread) suitable for standard NPT plumbing installations.
  • Electrical: Solenoid coil designed for 22–28 VAC operation; low current draw (approximately 0.10 A at 24 VAC) for long wire runs and controller compatibility.
  • Field features: Lightning-protected, slow-close action with no water hammer, fully serviceable diaphragm assembly, and consistent performance on slopes or hilly sites.

The 2230H combines Griswold’s proven diaphragm-guided design and a watertight, epoxy-molded solenoid for dependable on/off control and pressure reduction in commercial or residential irrigation systems.
