DYNAJET dry-closing high-pressure guns

Expert knowledge high-pressure innovations

DYNAJET high-pressure guns always have an internal tightly-closing valve at a working pressure of up to 1,000 bar. The water jet is interrupted immediately when the DYNAJET guns are released. This makes working a lot easier and saves on water too.

The DYNAJET HELI valve

Dry-closing high-pressure guns always need an unloader valve, such as the HELI valve. Pressure peaks are generated when the gun is released. Because of the direct connection of motor and pump, water is pumped during working breaks. Due to these pressure peaks, the valve automatically switches to bypass to relieve the gun. The HELI valve reduces the pressure in the hose to a small residual level. When the gun is activated again, the pressure builds back up with a slight delay, which makes handling noticeably smoother and easier.
