INTERPUMP K1 ZERO UNLOADER VALVE
Code: 1976
Product detailed description
The INTERPUMP K1 ZERO-PRESSURE UNLOADER VALVE – 250 BAR / 41 L/MIN is a compact and advanced bypass valve designed by Interpump, a leading name in high-pressure cleaning technology. Built to operate at pressures up to 250 bar and flow rates of 41 liters per minute, this valve incorporates a zero-pressure system that automatically discharges residual pressure from the delivery line when the spray gun is closed.
This safety-enhancing feature makes the K1 especially suitable for non-professional users in environments such as self-service car wash systems, compact pressure washers, and portable cleaning units. The design minimizes risk and increases operator comfort by eliminating sudden recoil or pressure retention in the hose.
Designed for small-scale applications across sectors such as automotive cleaning, agriculture, and light municipal cleaning, the Interpump K1 ensures professional-grade control in user-friendly systems.
Applications:
-
Self-service car wash stations
-
Compact and portable pressure washers
-
Automotive and agricultural cleaning setups
-
Light-duty municipal cleaning tasks
-
Cleaning systems designed for public or semi-professional use
With its Interpump engineering quality and integrated zero-pressure system, the K1 valve delivers safety, ease of use, and performance in compact high-pressure cleaning systems.
