Select valves and fittings with appropriate pressure ratings
Make the process connections as shown in Figure 7-1. Be sure that valves and fittings (S1) have
sufficient pressure ratings to withstand pressure peaks which will occur when process flow is
blocked.
Minimize liquid volume in system
Keep pipe sizes small and couplings close to minimize the liquid volume in the system. Smaller
volumes require less time to rinse.
