Pressure Regulators

Pressure Regulators are manufactured with non-corrosive, high quality plastic and brass, that withstands all fertilizers and chemicals in common use providing years of trouble-free operation. The one-piece sealed regulating unit - different for each pressure option - is field replaceable and easy to maintain. Available in several sizes, pre-set pressures, and flows from .25 to 175 GPM.

Product Advantages

  • Instant response to variations in pressure assuring that outlet pressure will remain constant regardless of inlet pressure.
  • Non-corrosive, high quality plastic and brass bodies withstand commonly used fertilizers and chemicals.
  • Sealed regulating unit with stainless steel spring and a screw are field replaceable and easy to maintain.
  • Built-in operating indicator visually shows when proper outlet pressure is achieved (except 3/4" low flow).
  • Flow ranges from .25 to 175 GPM

Applications

  • For use in drip and sprinkler irrigation systems.

Pressure Regulating Unit

  • Quick and simple to change pressures
  • One-piece sealed pressure regulating unit for each pressure option
  • Pressure regulator body remains the same
  • No spring colors to remember

Example :

  • Given Flow Rate = 63 GPMNominal Required Pressure = 20 psi
  • Using Pressure Regulator Model 2” x 6 will result in 10.5 GPM per regulating unit.
  • 10.5 GPM per regulating unit will result in an output pressure of 18 psi. (See chart at right)
  • Headloss of 2” x 6 Pressure Regulator at 63 GPM is 5 psi. (See chart at left)
  • Design pressure at inlet of Pressure Regulator should be 18 ÷ 5 = 23 psi
