Pressure drop problem
Pressure drop problem
(OP)
HI there,
now i am facing a problem about the pressure drop in ball valve. our company produce a kind of ceramic ball valve against high corrsion and high temp, which was inquried by a mid-east petrochemcial company. the engineer ask for the pressure drop of our reduced ball valve. the ball valve we ganna provide is a reduced version: inlet is 4", but the orifice of ball is only 3", so there must be some pressure drop exist. however, our company never do this kind of experiment to test the flow rate, so is there anybody has any method to give the approximate pressusre drop calculation method. thanks in advance!

Engineers had responsibility to fit goods which not only complied with standards and specifications but came from companies who have both the experience and background to know what they are doing. Has this now all gone?
I too would question the purchase of valves from this manufacturer.
