5.the body is designed without gate slot,the smooth passage will not get impurities filling up,more applicable for sewage working condition.

6.the integral seal works ralialy,for the high pressure seal,leaving zero leakage under 1.5 times nominal pressure and  for the low pressure one,under 0.02mpa.
