Double block and bleed valve block
Modular double block and bleed valve blocks are an ideal solution for compact shut-off and bleed valves in a one-piece forged housing and with a wide range of end connections, housing forms and valve variants. They form the interface between process and measuring instrument and allow the shut-off, bleeding and protection of instruments or transducers. The compact design reduces not only weight and costs, but also the number of possible leak points in the system.

Modular Valves for Single Shut-off – SB Series
The modular Hy-Lok SB Series double block valves serve for simple shut-off and bleeding of pressure measuring instruments. They are installed directly on the process flange or boiler. Instruments can be installed directly on the valve outlet or alternatively connected via pressure gauge or transmitter pipelines. The double block & bleed valve blocks serve also to protect instrumentation during the process.
Hy-Lok SB Series double block valves are designed for different instrument configurations.
The double block valves serves for simple shut-off, the instruments are designed for high pressures and temperatures. In addition to the valve block, Hy-Lok offers instruments such as shut-off valves (ball cocks) as well as globe valves and mounted valves as needle valves.
