This valve is widely used in urban gas, central heating, heat exchanger, steel works and various industrial equipment.
The length of the valve body and the height of the stem can be adjusted according to the construction and design requirement
of the pipeline.
The valve is integral welding and there will be no leakage. There are two connections: welded and flanged.
The operations are handle and gear (vertical/horizontal).
The warranty is 12 months under normal operation after installation.
Design standard:API 608-2002.Flanges according to DIN 2501 PN 10/PN 16/PN25/PN 40;GOST 12815(PN 10/PN 16/PN25/PN 40).
