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.
