LD Union Ball Valves

LD union connections and ball valves

LD union connections and ball valves are practical components for modern water supply and heating systems where easy installation and servicing are important. The union-nut design allows a radiator, pump, manifold or other item of equipment to be disconnected without rotating or dismantling the entire pipe run. This saves time during initial installation and makes future maintenance considerably easier.

Suitable products in the LD Pride range use a robust brass body with a nickel-plated exterior. The plated surface helps protect the fitting in humid plant rooms and maintains a neat appearance. Sealing elements used around the ball and seats are designed to provide reliable shut-off when the valve is selected and installed correctly.

Typical applications

LD union ball valves can be used on hot and cold water services, radiator connections, boiler systems, underfloor-heating manifolds, pump connections and technical pipework. Their modular construction is especially useful wherever a component may need to be removed or replaced without disturbing the rest of the installation.

Models may be available in straight or angle configurations, with different thread sizes and handle options. A butterfly handle is convenient in restricted installation spaces. Pressure and temperature ratings depend on the exact diameter and article number. Some LD Pride union models in DN15–DN25 are rated PN40, while other sizes or configurations may have different limits. The technical data for the selected product must therefore be checked before installation.

Selection and installation

Choose the valve according to pipe diameter, male or female thread arrangement, straight or angle layout, working medium, pressure and temperature. Correct thread sealing, stress-free pipe alignment and controlled tightening of the union nut help preserve sealing performance and service life.

LD union ball valves are a convenient choice for domestic and professional installations that require neat assembly, fast servicing and dependable isolation. Euroclima offers LD union valve options for different system layouts and connection sizes.
