EZ-C:
J Micro-Flute and J Micro-Flow trim
1. Valve size number is end connection s ize by normal trim size. For example, an NPS 6X4 EWT-C valve has NPS 6 end connections with NPS 4 trim (see table 4).
2. Do not exceed the pressure or temperature limits in this bulletin, and any applicable code limitations.
3. UHMWPE stands for ultra high molecular weight polyethylene.
4. A spring is used only with PTFE V-ring packing. A lantern rings replace the spring in other packing arrangements.
5. Down is in through the cage and out the seat ring (see figure 1).
6. Class V shutoff cannot be performed with water. The residual trapped moisture from testing with water can cause valve and trim damage from the ice crystals formed at below freezing
service temperatures.
