Supplier Fisher Type 167DAS-13/CBF Switching Valve, Jakarta
WWW.DISTRIBUTORALATINDUSTRI.COM | Supplier Fisher Type 167DAS-13/CBF Switching Valve, Jakarta | Fisher Type 167DAS-13/CBF Switching Valve is a pneumatic switching valve designed to automatically switch or route instrument air signals when a preset control pressure is reached. It is commonly used in pneumatic control systems for valve sequencing, interlocking, signal switching, and fail-safe applications. The valve provides reliable operation in demanding industrial environments such as oil & gas, petrochemical, power generation, and chemical processing plants
Supplier Fisher Type 167DAS-13/CBF Switching Valve, Jakarta
The valve is spring-loaded and pressure actuated, allowing it to change the flow path of compressed instrument air between output ports when the inlet control pressure reaches the preset switching point.

Operating Principle
The Fisher Type 167DAS-13/CBF Switching Valve uses a diaphragm and spring mechanism to monitor the control pressure. As the inlet pressure increases and reaches the preset spring setting, the internal spool or valve mechanism shifts, redirecting the pneumatic output to another port. When the pressure falls below the reset value, the valve returns to its original position, providing reliable pneumatic signal switching.
