True Union Ball Valve

True union ball valves combine a full-bore flow path with a removable union connection at both ends, giving plants a valve that delivers strong pressure performance while remaining easy to service or remove from the line.

Key features:
• Full bore design with thicker wall thickness supports pressure ratings up to PN16 in UPVC, CPVC, and PVDF materials.
• An optional locking device secures the handle in the fully open or fully closed position for operational safety and lockout procedures.
• Sizes DN15-50 are rated for full vacuum service, extending suitability into negative-pressure applications.
• Body length exceeds HG-standard design requirements, allowing a thicker ball, thicker PTFE seal, and stronger inner plug and thread for greater long-term durability.
• The valve can be converted from manual to automatic (pneumatic or electric) actuation without replacing the body, protecting the initial installation investment as automation needs evolve.
• A bottom stand with an insert hole allows the valve to be secured to a bench or panel using only a metallic insert, without additional bracketry.
• Removing the handle and placing the raised lugs into the carrier allows quick, tool-light disassembly for maintenance.

Field experience shows that installation errors in factory piping can place uneven stress on union nuts, leading to leakage or nut damage over time in larger sizes. For this reason, the union connection style is recommended for use up to DN50, with larger diameters better served by flanged ball valve designs.

Typical applications include process skids, water treatment systems, vacuum lines, and installations that may later be automated, making this valve a flexible choice for engineers who want the option to upgrade actuation methods without redesigning the piping.
