The Trapped Pressure VB9 Unloader Valve with Pressure Switch is designed to improve the safety, performance, and efficiency of high-pressure washing systems. This innovative valve reduces pump pressure to zero while trapping line pressure within the high-pressure hose, ensuring uninterrupted operation and protection of the system components.

Equipped with a pressure switch and electrical wiring, the VB9 unloader valve offers a comprehensive solution for precise pressure control and monitoring. The fixed bypass port ensures smooth and efficient operation. Built to handle demanding applications, it supports a maximum pressure of 220 bar (3000 psi) and a flow rate of 30 liters per minute at 90 C, making it ideal for high-demand industrial and commercial cleaning tasks.

Key Features:

•  Trapped Pressure Design: Reduces pump pressure to zero while keeping pressure in the high-pressure hose for optimal performance and protection.
•  Pressure Switch: Comes with electrical wiring and pressure switch for enhanced control and safety monitoring.
•  Durable Construction: Features a fixed bypass port and 3/8" female inlet and outlet connections for reliability in tough environments.
•  High-Pressure Capacity: Handles up to 220 bar (3000 psi) and a flow of 30 liters per minute at 90 C, making it suitable for demanding cleaning tasks.
