HS Series Shut-off Valve

HS series shut-off valve is a safety device for gas transmission systems, particularly in pressure regulating stations. They automatically cut off gas flow when system abnormalities cause pressure to reach predetermined setpoints (over-pressure or under-pressure), providing critical protection. Suitable for natural gas, manufactured gas, liquefied petroleum gas (LPG), and other non-corrosive, pretreated stable gases.
