Quick Closing Valve Ductile Iron Straight Flange DIN PN 16
TECHNICAL CHARACTERISTICS
Quick-closing valves are most often used in fuel systems where there is a need for immediate shut-off of the flow. The built-in universal universal cylinder for mechanical, hydraulic or pneumatic activation provides automatic remote control of the valve. In the event of a fire or a dangerous increase in ambient temperatures, the valve automatically closes by additional protection, installed in accordance with SOLAS Ch. 11-2 / Reg. 4 / 2.2.3.4, which requires valves installed on tanks containing flammable liquids to immediately cut off all flow in the event of a fire.
WORKING FLUIDS / MEDIUM
Fuels, oils, aggressive liquids
EXECUTION
End stop for position indication.
Dimensions: DN-50-150
