Self-Closing Valves Malleable Iron Angle With Weight DIN PN 16

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

• Steel 1.0619
• Various flange connection standards – ANSI / JIS
• 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).

Dimensions: DN 15 – 80


Description

The Self-Closing Angle Valve in malleable iron is engineered for superior durability and reliable performance in demanding industrial applications. Designed to meet DIN standards and rated for PN 16 pressure, this valve ensures safe and efficient fluid control with its self-closing mechanism, which automatically shuts off flow when released, preventing leaks and enhancing operational safety. Its robust construction from high-grade malleable iron provides excellent resistance to corrosion, mechanical stress, and high temperatures, making it ideal for use in water supply, heating systems, and industrial pipelines.Key features of this valve include:Self-closing action for automatic shut-off and leak preventionConstructed from malleable iron for strength and longevityComplies with DIN standards and PN 16 pressure ratingAngle design for easy installation in tight spaces and directional flow controlSuitable for water, steam, and non-aggressive media applicationsIdeal for plumbing, HVAC, and industrial systems, this valve offers easy maintenance and compatibility with various pipe configurations. Its precision engineering ensures smooth operation and long service life, reducing downtime and maintenance costs. Upgrade your fluid handling systems with this dependable, high-performance self-closing angle valve.
