Based on Clippard’s original spider design from 1973, the EVP’s ar- 5
mature is the heart of the valve which provides precise flow control.

To determine the correct orifice required, locate the colored line immediately above the flow/pressure intersection
Example: 9 slpm required at 45 psig inlet. This example leads to a “-2545” valve (0.025” nozzle, 45 psig).
