Single Block And Bleed Valves

are compact, high-integrity isolation solutions designed to replace multiple valve assemblies with a single, space-saving unit. These valves incorporate an isolation valve (block) and a bleed valve in one body, allowing safe removal of instrumentation or venting of trapped media without disturbing the main process line.

Our SBB valves are precision-engineered to meet stringent performance standards and are suitable for oil & gas, chemical, refineries, power generation, and offshore/onshore applications where high pressure, high temperature, and system integrity are critical.

Available in a variety of configurations, pressure classes, and end connections, Metalok SBB valves are machined from high-grade materials such as SS 316, Monel, Hastelloy, Inconel, and Duplex, ensuring long service life in aggressive environments.

Integrated Block and Bleed Function
Combines isolation and bleed in a single valve for efficient pressure release and maintenance.
Compact Design
Reduces space, weight, and potential leak paths compared to traditional multi-valve assemblies.
High Pressure Capability
Rated up to 10,000 PSI, suitable for critical high-pressure applications.
Soft or Metal Seats
Available with PTFE, Graphite, or metal-to-metal seating based on service conditions.
Multiple End Connections
Offered with NPT, BSPT, Flanged, Socket Weld, Butt Weld, or Double Ferrule Tube Ends.

Enhanced Safety
Provides a secure means of venting pressure before maintenance or disassembly.
Reduces Leak Points
Single body construction minimizes threaded connections and potential leakage.
Saves Installation Space
Combines multiple valves into one, reducing weight and system complexity.
Simplifies Maintenance
Allows easy isolation and pressure relief without disrupting the process.
Improves System Reliability
Fewer connections and moving parts enhance operational integrity.
