SMC VHS501-N06 NSNBC01 Industrial Vacuum Generator

SMC VHS501-N06 NSNBC01 Industrial Vacuum Generator is part of SMC’s VHS series of residual‑pressure‑relief 3‑port valves, a compact device designed to vent residual air in pneumatic vacuum systems and prevent unintended suction when maintenance is performed.

Designed with a 3‑port layout, the VHS series uses a supply port labeled 1(P) and an exhaust port labeled 3(R); the handle orientation makes the air flow direction easy to verify at a glance.

The VHS family is engineered to reduce the risk of accidents by releasing residual pressure before servicing equipment, a safety feature that enhances performance in automated and vacuum‑related lines.

Construction aligns with the VHS50x family, including a body manufactured from ADC12 alloy and a compact footprint; several variants list a target weight around 0.25 kg.

Thread options and port sizes for VHS units typically include Rc, G, and NPT configurations to fit a range of piping standards.
