Pressure Regulators are a very important part of your Irrigation System. Drip Systems need a properly matched pressure regulator to ensure that the system is run safely. We carry Senninger and Netafim Pressure Regulators. These are standards in the industry.
ToroAg says: Pressure Regulators are installed to protect downstream components from excessive pressures. They are especially important in drip irrigation systems because the plastic and PE construction materials typically have lower pressure ratings than conventional sprinkler systems.
