Flow cotrol valves
Flow cotrol valves Key features Fuctio Flow cotrol or oe-way flow cotrol valves regulate the pisto speed of peumatic drives durig advace ad retur strokes. This is doe through suitable restrictio of the flow rate of compressed air i exhaust air or supply air directio. With the oe-way flow cotrol valve GRLA or GRLZ, the flow cotrol fuctio works i oe directio oly (exhaust air or supply air); the o-retur fuctio works i the opposite directio. With the flow cotrol valve GRLO, the flow cotrol fuctio is active i both directios. The flow cotrol fuctio creates a adjustable aular gap iside the valve. This gap ca be icreased or decreased by turig the kurled screw or slotted head screw. The required restrictio ca be set with the help of this adjustmet compoet. -H- Note The documetatio for the oe-way flow cotrol valves ca be foud at www.festo.com/catalogue Geeral iformatio Stadard omial flow rate qn The stadard omial flow rate qn is the flow rate based o stadard coditios at a operatig pressure of p1 = 6 bar ad a output pressure of p2 = 5 bar, measured at room temperature t = 20 C. Stadard flow rate q The stadard flow rate is measured at a operatig pressure of p1 = 6 bar ad a output pressure with respect to atmospheric pressure (p2 = 0 bar).

Ucotrolled supply air ad cotrolled exhaust air move the pisto betwee air cushios (improves motio, eve with load chages). Supply air oe-way flow cotrol fuctio Adjustable speed durig advace ad retur strokes. The flow rate is idetical i both directios. Sigle-actig cylider with oe-way flow cotrol valve Exhaust air ad supply air oe-way flow cotrol fuctio Adjustable speed durig advace ad retur strokes. The flow rate ca be adjusted differetly for both directios. Sigle-actig cylider with flow cotrol valve Flow cotrol fuctio i both directios Speed adjustmet through flow cotrol o both sides is ofte applied i the case of sigle-actig or small cyliders. The beefit of this applicatio lies i its simplicity. Applicatio examples Mii slide SLT Flat cylider DZF Multimout cylider DMM 2017/11 Subject to chage Iteret: www.festo.com/catalogue/... 3
