SMC Corporation VSS8-4-FG-S-3VZ Pneumatic Solenoid Valve

SMC VSS8-4-FG-S-3VZ is a compact, ISO 15407-2 5‑port, 2‑position pneumatic solenoid valve from the VSS family, designed for base‑mounted installation. It uses a single 24 V DC piloted solenoid to drive a 4‑way, 5‑port spool that directs compressed air to actuators, featuring a Cv of 1 and a flow capability up to about 1000 L/min (ANR). The valve has metal seals, operates on air or inert gas, and employs a base‑mounted piping configuration for straightforward panel mounting; an aluminum die‑cast body supports a compact footprint of roughly 65 mm in height, 188.5 mm in length, and 38 mm in width. Electrical characteristics include 24 V DC coil voltage, 1 W power consumption (42 mA), and a non‑locking push manual override for field testing or manual actuation. The unit adheres to ISO 15407-2 standards, with a 23 to 140 °F (−5 to 60 °C) operating temperature range and a maximum operating pressure of 101 psi (about 7 bar), making it suitable for precise, high‑reliability pneumatic control in compact automation setups.
