Patent attributes
A valve head assembly for a hydraulic fracturing pump. The valve head assembly includes a valve body attached to a valve leg assembly with backward swept or delta shaped legs. Each leg is attached to a main leg shaft which extends along a main axis. Each leg has a first leg segment and a second leg segment. The first leg segment has a first end that attaches to a distal end of the main leg shaft and extends along a first leg segment axis back towards the valve body. The second end of the first leg segment attaches to the second leg segment which extends along a second leg segment axis that is substantially parallel with but spaced apart from the main axis. The first leg segment may form an angle between the main axis and the first leg segment axis that is between approximately 10 and 60 degrees.
