Gate valves
Flanged Gate Valve PN16 (Resilient Seat, GGG-50)
The standard gate valve for professional water networks. Manufactured in GGG-50 ductile iron with a 250-micron epoxy coating, its resilient-seated wedge and stainless steel stem guarantee total reliability at PN10 and PN16 working pressures.

This gate valve is the mainstay of any modern water supply or irrigation network, designed to offer impeccable performance and exceptional durability in the most common working conditions (PN10/PN16). It combines the same high-end features as our high-pressure models, making it the quality standard for all types of projects.
Its construction is based on a robust GGG-50 ductile iron body, a non-rising AISI-420 stainless steel stem and a resilient-seated wedge that ensures 100% tight shut-off. The full-bore design minimises head loss and prevents debris build-up.
Protected with a 250-micron layer of epoxy paint inside and out, and with a triple-seal system on the spindle, this valve is built to be installed and forgotten, guaranteeing decades of maintenance-free service.
