According to BS 6364 standard, para. A.3.1.4(d), the maximum allowable seat leakage is
100 mm3/s per mm of ND = 150 ml/min per in of DN,
for all valve types except check ones (that are allowed two times the above mentioned leakage).
Shell MESC SPE 77/306 specification in now withdrawn, as it has been superseded by Shell MESC SPE 77/200 in June 2007.
Hope this helps, 'NGL
