November 28, 201510 yr still confused about which valve to use on the new kinyon hammer. parker has two valves with 3/4 inch ports, one is called an inline single (B834) and the other an inline double(B844). plans call for a norgren valve which according to their catalog is a single with spring return/air pilot. posts here and elsewhere advise not to use a spring return type. at this point i am lost in numbers and terminology i don't have a handle on. any help greatly appreciated.
November 30, 201510 yr I use Norgren valves, 1/2 in ports on the 5-port, 1/4 in port on the roller shuttle. I dont see the need for 3/4 inch ports unless the air cylinder is similar equipped. 5 port valve is Norgren MN01CGA73A000,, Mcmaster # 6124K36 Roller shuttle is Norgren X3064222,, Mcmaster# 8277K14 If you get the hammer running to your liking, I recommend buying spares to keep on the shelf.
January 28, 201610 yr .I had a Norgren valve fail almost out of the out of the box..Got to say it..Run from Norgren Virtually no customer support. You can't rebuild them (no parts), Low CV They couldn't give me a replacement because they didn't have any at the factory and none at any of their distributors. Told me to wait till the next production run of that model. Didn't know when ! Contacted PARKER, outstanding customer service. Walked me through my application and they had parts on the shelf. # B834OOOXXA If you see green grease seeping out of the Parker valve, it's just assembly grease. This valve has been running 5 + years. Keith
