Sealed Valve

PublishTime：2022-09-05

●Although good Industrial practices always demand the use of filtered, clean air to ensure smooth operation, consideration need to also be given to environmental ingress into the valves through the exhaust ports and the solenoid operators.
●There are a few key areas of any valve that, if left unprotected, can put solenoid valve reliability at risk due to ingress issues. We particularly recommend protecting all exhaust ports, body and the solenoid when specifying a valve.
●Exhaust Protection
▲DE –The ideal solution should provide a solid seal against ingress when the exhaust port(s) are inactive while also providing maximum valve flow when exhausting. The dust, dirt, and moisture excluder is fitted onto the exhaust port and only open when the valve is exhausting.
▲DG/DD – The Dust Proof option removes the external vent from behind the pilot piston, and instead directs the air through a gallery in the valve plunger into the springcap, thereby creating a closed loop. By removing the vent, any possible dust and/or moisture intrusion is eliminated.
●Solenoid Protection
▲PC – Solenoid operators are significantly vulnerable to the effects of unwanted ingress. One option is to pot the solenoid coil in the housing using epoxy resin to ensure moisture protection. The option -PC is available to add this protection to our XX and XN solenoid operators.
▲The second option is to select a solenoid operator that makes use of a sealed housing to achieve ingress protection. The XDB, XV, and XT solenoid operators are rated to IP68, giving complete protection to the electrical components.
▲D14 – The D14 Dust and moisture excluder for the solenoid pilot exhaust port is comprised of a flexible seal sitting in a chamfered groove covering several exhaust drillings. When the solenoid exhausts, the seal flexes to allow the air to pass. Once exhausting is complete, the dust excluder again seals off the internals from the environment.
●Stepping It Up
Many of our solenoid operators are already IP rated to IP68, but when combined with the D14 exhaust port protection and the DG/DD dust proof assembly (with no external venting), we can certify our complete valve with an IP65 rating. This gives total protection against dust and low-pressure water jets from all angles.
