The AR40236 Jetter Valve from Annovi Reverberi is designed to convert standard triplex plunger pumps into powerful sewer cleaning systems. Made in Italy and built for durability, this pulsator valve fits XW Series pumps and operates at a maximum pressure of 4000 PSI. Its innovative design features an adjustable lever that allows users to easily switch between standard and jetting modes by turning the handle. When fully engaged, the valve disables the center valve of the pump, creating a pulsating action that enhances the jetting effect needed for efficient pipe and sewer cleaning. Ideal for professionals seeking versatility and performance, the AR40236 is a reliable solution for demanding pressure washer applications.
