The valve works fine. Only thing it doesn't come with information for use with power beyond. There is no P or BY on valve it has N which can be used for power beyond if you get orphis to fit.
Seems like a lot of other comments say the thread is British or O ring boss #8 or half inch I’ve found my valve to be national pipe thread… what ever just change the fittings
I bought this valve to put on my tractor to do away with the 2 lever valve that was on it .the price was amazing and the quality and performance is awesome I've had it on my tractor for a year now and best choice by far.
