A Paddle Blank is a safety device used in piping systems to provide positive isolation of a section of a pipeline. It consists of a solid metal plate designed to be installed between two pipe flanges, creating a physical barrier that completely shuts off the flow of media.

Unlike valves that may leak over time, a paddle blank guarantees a 100% leak-proof seal, making it essential for maintenance, safety, and testing operations.

Key Features & Benefits:

Positive Isolation: Provides absolute shut-off by creating a metal barrier, ensuring zero leakage for maximum safety.

Visual Identification: The extended handle clearly indicates whether the line is open (if used with a spacer) or closed (blank installed).

Versatility: Suitable for a wide range of industries and media, including liquids, gases, and steam.

Durability: Engineered to withstand high pressures and temperatures, with no moving parts to wear out.
