TS EN 736-1

TS EN 736-1 is a terminology standard for valves, prepared to establish common denominations for valve types and to support a uniform, systematic vocabulary across the valve family. Valves are key components in fluid systems, used to start, stop, throttle, divert, or otherwise control flow. The focus of this document is not to approve a particular valve design, but to make sure different valve types are described with the same terms in a consistent way.

Why consistent valve naming matters

In general technical use, valves can differ widely in body construction, closure element, motion pattern, and flow path geometry. Names such as gate, globe, ball, butterfly, or check valve convey both the intended function and clues about operating principle. Standardized terminology helps ensure that catalogues, drawings, maintenance documents, and procurement specifications use the same words with the same meaning. That consistency improves equipment selection, system design, and day-to-day communication.

What this standard covers

Based on the supplied scope, TS EN 736-1 specifies the denominations of valves and aims to provide a uniform and systematic terminology for all types of valves. It should therefore be understood as a terminology document centered on names and definitions of valve types. It establishes the common language of the valve family, but it does not, on the basis of the supplied scope, set performance requirements, dimensional limits, or test procedures for individual products.

• Provides a common and systematic naming framework for valve types.
• Supports consistent communication in fluid system and valve terminology.
• Helps distinguish different valve designs without confusing their names.
