Sku#: VHS40-N04-Z-D
The SMC VHS40-N04-Z-D pressure relief valve is built for industrial pneumatic systems that require reliable pressure relief, controlled air shutoff, and energy isolation. As part of SMC’s VHS-D series, this 3-port pressure relief valve is commonly used with SMC AC-D modular F.R.L. air preparation equipment and helps provide a simple way to isolate and release downstream pressure during service or maintenance.
This model includes a VHS40 body size, 1/2 in. NPT port size, and psi unit labeling. The single-action handle operation makes the valve easy to use, while the lockable design supports energy isolation procedures in pneumatic systems. SMC’s VHS-D series also offers multiple configuration options, including different body sizes, thread types, port sizes, handle options, flow directions, and silencer options depending on the application.
The VHS40-N04-Z-D is a good fit for OEM equipment, production machinery, pneumatic control panels, and general factory automation systems where dependable air preparation components are needed. When used as part of a properly designed pneumatic system, this valve helps operators and maintenance teams manage compressed air safely and efficiently.
