What Are Monoblock SBB & SB Valves?

Indra Monoblock SBB and SB valves provide a compact and reliable solution for instrument isolation and venting, integrating shut-off and bleed functions into a single body. Designed for direct mounting to pressure instruments, they reduce installation complexity while ensuring high integrity and safe operation in high-pressure services.

The one-piece forged body provides superior strength and durability. The series accommodates threaded, flanged, butt-weld, socket-weld, and hub connection options, including mixed inlet/outlet combinations, for easy integration with process lines and pressure instruments across any installation requirement.

Key Features

One-Piece Forged Body

Superior strength and durability, rated up to 15,000 PSI, eliminating internal weld points and ensuring pressure boundary integrity under extreme conditions.

Connection Versatility

Accommodates threaded, flanged, butt-weld, socket-weld, and hub inlet/outlet combinations, including mixed configurations, for easy integration into any process system.

Hub Connection

Compact, clamp-style mechanical interface designed for high-pressure and subsea service, providing significant weight reduction and superior vibration resistance.

Compact System Replacement

Streamlined alternative to multi-valve "Christmas tree" manifolds, reducing weight, installation effort, and system complexity while enabling direct instrument mounting.
