SMC VHS20-F02 Lockout Shut Off Valve 0.1-1.0MPa G1 4 Ports

SMC VHS20-F02A-B Lockout Shut-Off Valve is a compact pneumatic safety device that isolates and depressurizes a main air line or panel during maintenance, featuring a manual locking mechanism to prevent unexpected re‑pressurization. This four‑port unit operates in a 0.1–1.0 MPa range and uses G1/4 threaded ports for standard pneumatic fittings, making it compatible with common air‑prep and control line assemblies. An aluminum body keeps the unit lightweight yet durable, with data indicating a maximum operating pressure of 1.0 MPa and a minimum operating pressure around 0.01 MPa depending on the exact variant, while many listings emphasize the 0.1–1.0 MPa working window. The VHS20 family is widely employed at air intake points, control panels, and preparation stations where lockout is required to ensure safe servicing, and the built‑in locking feature helps secure the line until the mechanism is released. When selecting this model, confirm the G1/4 port size and four‑port configuration to match your plumbing layout and space constraints.
