Hollow Jet Valve

Paint Coating : Electrostatic epoxy powder (RAL 5005 or 5015) with min. thickness 250 micron.

Hallow screw type :

These valves are divided into two main groups manual and electrical. Both types come with a balancer chamber inside the valve (inside of the piston). Water goes into the chamber piston through the holes which are located on the face of the piston so it will reduce the hydrostatics pressure on the opposite surface of the piston, this means that pressure adjusting needs less force to obtain the minimum adjustment. Comparing Hallow jet valves with other valves, the adjustment force in Hallow jet valves is much less than others when the piston is thoroughly closed, all the packings are absolutely sealed. The movement of the piston governs by means of a screw that is under control. The Hallow jet screw type will apply either a manual or electrical actuator which works via conic gears (bevel gear), stem, and stem nut.
