Leakages are effectively prevented from the ShenHao Top entry ball valves because of an uni-body structure, this type of ball valve can be maintained and repaired at site under service condition to ensure an easy routine maintance; It is easy to remove the ShenHao's bonnet of these items to allow an easy access to the body cavity without dismantling the valve from the pipeline. Both ball and seat-rings can be taken out only by a set of special maintenance tools; this maintenance operation requires very small space around the valve, which make it as the perfect solution whereever space or on-line maintenance is a headache.
