Gate Valve Gear Operated With Extended Stem API600
Gate valve is one of the most common on-off valves. It uses the up and down movement of the gate plate to connect (fully open) and cut off (fully closed) the fluid medium in the pipeline.
I. Purpose and Characteristics
Gate valve is one of the most common on-off valves. It uses the up and down
movement of the gate plate to connect (fully open) and cut off (fully closed)
the fluid medium in the pipeline. It is widely applicable to pipelines of
various systems in petroleum, chemical, hydraulic, and thermal power stations to
cut off or connect pipelines.
1. Low fluid resistance. The sealing surface is less scoured and eroded by
the medium (the gate plate has a high opening height).
2. Opens powerfully. Has good sealing performance. The medium flow direction
is not restricted, without disturbing flow or reducing pressure.
3. Simple in shape. Good in manufacturing technology and has a wide range of
applications.
II. Product Implementation Standards
American standard gate valves comply with API600/API6D standards.
Casting gate valves comply with ISO10434.
American standard valves comply with ASME B16.34 standards.
Structural length complies with ASME B16.10 standards.
Flange dimensions comply with ASME B16.5 standards.
Butt welding complies with ASME B16.25 standards.
Testing and inspection comply with API598/API6D standards.
