SMC VHS30-F03B 101-8MN

SMC VHS30-F03B Manual Shut-off Valve

Description

The SMC VHS30-F03B is a high-quality 3-port residual pressure release valve, designed for enhancing safety in pneumatic systems. By turning the manual handle, you can shut off the upstream air supply and exhaust any residual downstream pressure, preventing accidental machine operation during maintenance or servicing. Its robust construction and clear visual indicator (Red handle) make it an essential component for any industrial safety protocol. The valve is also lockable in the exhaust position for compliance with lockout/tagout (LOTO) procedures.

FAQ

What is the purpose of the built-in silencer on the VHS30-F03B?

The porous, white component on the exhaust port is a silencer. Its function is to reduce the noise generated when compressed air is rapidly vented from the system to the atmosphere. This is important for both worker comfort and safety in industrial environments.

Can this valve be used for vacuum applications?

The standard VHS series is designed for positive pressure applications (0.1 to 1.0 MPa). While some configurations might handle a slight vacuum, it is not its primary design function. For dedicated vacuum use, SMC offers specific valve series designed to handle negative pressure without leaking.

What does the ‘lockout’ feature on this valve do?

The handle has a provision to insert a padlock when it is in the closed (exhaust) position. This is a critical safety feature for Lockout-Tagout (LOTO) procedures, ensuring that the air supply cannot be accidentally re-energized while a technician is performing maintenance on the machinery.
