F4 Resilient Seat Wedge Gate Valve - PN16
Resilient seat wedge gate valves designed to EN1074, flanged to EN1092-2 PN10/PN16, with face-to-face according to EN558 S14 and rated to 16 Bar.
These robust gate valves have an elastomer encapsulated wedge for superior sealing, suitable to shut off or isolate water and neutral fluid pipelines.
The valves are manually operated by rotating the handwheel or stem cap to articulate the wedge long a non-rising threaded stem, they can also be fitted with an intelligent electric actuator or a gearbox.
