Self-Closing Valves Bronze With Weight For Measuring Pipes DIN PN 2.5

TECHNICAL CHARACTERISTICS

Self-closing valves with “weight” are most often used in water or fuel systems, in which the valves are normally “closed”. The valve is opened by lifting the weight, relying on it to subsequently self-close again. The latter is used to avoid “forgetting” the valve in the open state – for process safety. Seal – metal / metal.

WORKING FLUIDS / MEDIUM

Water, thermal oil, fuels, oils, flammable hydraulic oils, non-flammable hydraulic oils, petroleum, boiler feed water, condensate and seawater.

EXECUTION

Other materials upon request

• The installation is carried out in a position that ensures the correct operation of the valve (such that when the lifting force ceases, the valve closes itself by gravity).
• It is possible to have a version for operation via a pedal with a lever mechanism.

Dimensions: DN-32-80


Description

Our bronze self-closing valves with weight are precision-engineered for measuring pipes in industrial applications, adhering to the stringent DIN PN 2.5 standards. Crafted from high-quality bronze, these valves ensure durability, corrosion resistance, and reliable performance in demanding environments. The self-closing mechanism, enhanced by an integrated weight, provides automatic shut-off to prevent fluid loss and maintain system integrity, making them ideal for flow measurement and control systems.Key features include:Constructed from robust bronze for long-lasting service lifeSelf-closing action with weight for automatic operation without external powerComplies with DIN standards for pressure rating PN 2.5, ensuring safety and compatibilityDesigned for easy installation in measuring pipe setups, reducing downtimeResistant to wear and corrosion, suitable for various industrial fluidsThese valves are essential components in industries such as water treatment, chemical processing, and HVAC systems, where accurate flow measurement and leak prevention are critical. Their design minimizes maintenance needs and enhances operational efficiency, providing a cost-effective solution for your piping infrastructure. Trust in our valves to deliver consistent performance and meet the highest industrial standards.
