Quick-Closing Valve Malleable Iron Angle Flanged 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
The QUICK-CLOSING VALVE in malleable iron is engineered for high-performance fluid control in demanding industrial environments. Designed to meet DIN standards with a pressure rating of PN 16, this angle valve ensures reliable shut-off and efficient flow regulation. Its flanged connections provide secure, leak-proof installation, making it ideal for pipelines requiring frequent operation and durability under pressure.Constructed from high-grade malleable iron, the valve offers exceptional resistance to mechanical stress and corrosion, extending service life in applications such as water supply, heating systems, and industrial processing. The quick-closing mechanism allows for rapid response in emergency situations, minimizing downtime and enhancing operational safety. This valve is suitable for use with water, oil, gas, and other non-aggressive media.Key features include:Robust malleable iron body for longevity and impact resistanceFlanged ends compliant with DIN standards for easy integrationPN 16 pressure rating, suitable for medium-pressure systemsAngle design optimizing space and reducing flow resistanceQuick-closing action for efficient flow control and safetyIdeal for HVAC, plumbing, and industrial installations, this valve combines technical precision with ease of maintenance. Its design ensures minimal pressure drop and high flow capacity, supporting efficient system performance. Choose this valve for reliable, certified quality that meets rigorous industrial requirements.
