Danfoss evr 4 or 6 solenoid leaking on o ring again oct 12
Has any one experienced a leaking solenoid valve on the o ring, we are aware of problems back in 2011 on earlier valves. Recently oct 12 we have had a couple fail and leak after 15 months of install on r404a sites.

I have had to replace ALL the O Rings on 2 store after 6 months. I did have 2 very large leaks due to the O Rings leaking. Both systems were Low and Med temp R407a

After retrofit from mineral oil to poe oil, you have to replace all rubber parts.

Danfoss has acknowledged a fault in the EVR6 valves and have replacement seal kits available. Would suggest contacting your supplier for repair kits.

Luke,
We've had over 300 valves replaced and we are currently replacing with Castel. There is a good bloke at WR Refrigeration who has helped us alot on this current issue. I've spoken with him a couple of times while out in the field his name is Andy i think he is the cabinet manager?
Might be worth giving him a call.

In 6 years the on,y danfoss solenoid i have seen fail was when a tech put one in. Back o front and another purchased a normally open txv ... Haha and another tech melted the diaphragm ... Un do and remove when soldering if you can't weld for s*** or have bad wrapping technique haha
interesting to hear about the re call...

In my opinion its hard to beat Sporlans Solenoid valves...the Metal Wolverine Gaskets rarely leak, even on a Low temp R-22 H.G.S.V's.
