Product Overview
The SMC VSA4240-04 is a pneumatically actuated process valve from the SMC VSA4000 series, engineered for precise control of compressed air and neutral gas media in industrial automation systems. This air operated valve utilizes an external pilot air signal to shift an internal spool mechanism, delivering reliable on/off flow control without the need for electrical solenoids at the valve body. With a 1/2 inch port configuration, the VSA4240-04 is designed for panel or inline mounting in pneumatic circuits requiring dependable, repeatable actuation. Its balanced spool design ensures consistent shifting force regardless of supply pressure fluctuations, making it a preferred choice for demanding process control environments where electrical actuation is impractical or undesirable.
