Hi all can anyone tell me where I can find 800 bar grease relief valves? The company I work for are looking to trial something other than burst discs on 994 liebherr digging machines.

I know of only units that go to 5000 psi, but check into track tensioner cylinders on larger tracked machines, some have reliefs.

Thanks Doug, yeah mate I can find 400 bar valves,I have been bashing my head against the wall with maintenance supervisors that they should stick with burst discs this just strengthens my resolve.
Thanks again mate

I think in the case of an Acura, the higher bypass may just be because the media can stand up to a greater pressure. The oversized Amsoil filter I run has a bypass that's substantially higher than the factory filter and no problems in over 70,000 miles
