Description:
The SMC VHS20-N01B-KZ is a 3-port residual pressure relief valve with 1/8 NPT ports that manually exhausts trapped air from pneumatic circuits once the main supply is shut off. Operators turn the handle to open the exhaust path while blocking the inlet, preventing unexpected startup or motion in downstream cylinders and tools. The compact body mounts directly in line and requires no external power or pilot signal. This model belongs to SMC's VHS series of safety valves used on air preparation assemblies, compressor outlets, and machine guarding systems where confirmation of zero pressure is required before maintenance or access.
