LIVE STRAINER & CONTROL SYSTEM FLUSHING

procedure can be performed while the valve is live (i.e. still in service) but it is recommended that the
downstream system is isolated (i.e. downstream gate valve closed).
a. Depressurised control system as per section 4.1.
b. Ensure BV1, BV2 and CS isolation valves are all closed.
c. Remove and clean the strainer by unscrewing the hex plug.
d. Flush the control system with water by slowly opening, one at a time, BV1 & BV2.
