Product Introduction
Pointed valves are very similar to linear blind valves. Also called gas shut-off valve for glasses. It can design two types: open and completely sealed. These valves can be manufactured in very large designs and are completely custom designed and manufactured depending on the process conditions. They can be closed or open and reach sizes up to 120 inches. Commonly used in gas blast furnaces or other low-pressure systems, they provide complete and reliable shut-off of downstream flow, providing 100% “human safe” closure.
Yi He googles that the valve uses a variety of seal materials depending on the operating temperature and environment - from elastomeric seals (e.g. CR, FKM/FPM, VMQ) to fiber gaskets and seal systems consisting of a soft sealing material with an additional metal seal. For valve body materials such as carbon steel, stainless steel, or customer specification.
◆ Nominal diameter: from 400 to 2800 mm
◆ Conditional pressure:0.05-0.25 MPA
