This steel wedge gate valve, DN 400 PN 1.6 MPa, is a pipeline shut-off valve with an extended spindle prepared for drive (actuator) mounting, intended for large-diameter water, steam and process lines. The valve is rated to seal tightness class A — the highest standard leakage class, permitting no visible leakage — with an assigned service life of 30 years and an assigned resource of 1500 open-close cycles.
The maximum torque required to operate the gate is 710 N·m, a figure that lets buyers size electric actuators precisely. Extended-spindle construction suits buried and chamber installations in district heating and water networks, where the operating mechanism must reach ground level.
Sold from two units, the valve addresses utility companies, pipeline construction contractors and industrial plant builders. Wedge gate valves remain the default shut-off architecture for large mains because of full-bore flow and decades-long service expectations, which this specification reflects directly.
