Gate valves are shut-off valves typically used in plants and pipelines; they channel fluids under pressure; not suitable for flow regulation as they would cause strong turbulence and vibrations.
The metal seal gates (seats in steel, bronze, brass) are full bore; the wedge adheres to the seats only when the closing is completed; sealing is guaranteed by the contact of the metal sealing ring placed on the disc and by the one placed on the body seat.
In valves with rubber wedges, which are also full bore, maintenance-free, the cast iron wedge has an elastomeric EPDM coating; in this case the sealing is guaranteed by the compression of the wedge lining in the seat arranged inside the body.
