SY5A*R, Vacuum Release Valve w/Restrictor

SMC has improved product performance and reliability with the redesigned SY series valve.  The SY3/5/7000 have the same valve width as their predecessors, but the flow has been increased by up to 80%, allowing the valve size to be reduced. A built-in strainer in the pilot valve prevents trouble caused by foreign matter. Improved solenoid and spool design makes the New SY the most durable valve in the market.  The valve is rated at 70 million cycles for the rubber seal and 200 million cycles for the metal seal.  Side, top and bottom port/pipe directions are available to allow flexible installation.  The SY is available in body ported or base mounted styles, and can be used individually or manifold mounted.

*** We are currently experiencing long lead times for some SY products.  Please consult with SMC Representative for alternatives such as natural color SY.  To order natural color SY, please add "-NA" at the end of the part number. ***
