Dn-25 sliding brass wing valve

DN25 brass globe-type valve with handwheel

🔧 The DN25 (1") handwheel-operated valve is used to open and shut off water or gas flow in a pipeline. Unlike a ball valve, which operates with a single 90° turn, this valve uses a multi-turn mechanism.

This construction allows the opening position to be changed gradually, providing more controlled operation. The valve can be installed in water-supply systems, near meters, filters and other engineering equipment.

🔄 How the valve mechanism works

Turning the handwheel moves a stem and shut-off element inside the body. Rotating it in one direction gradually closes the flow passage, while turning it in the opposite direction opens it.

🖐️ Compact wing-style handwheel

The wing-shaped handwheel provides a convenient grip without requiring a long lever. This makes the valve suitable for confined installation areas.

🔩 Brass body

The body is made of brass, a material widely used for plumbing shut-off valves. The DN25 size corresponds to a 1-inch connection.

⚠️ Before installation

Verify the following from the product marking or data sheet:

• exact thread arrangement;
• permitted working pressure;
• temperature range;
• shut-off element and seal materials;
