1. Valve size number is end connection size by normal trim size. For example, a 6X4 valve has 6-inch end connections with 4-inch trim.
2. Do not exceed the pressure/temperature limits in this manual and any applicable code limitation.
3. Maximum leakage is 0.05 mL/min/psid/inch port diameter.
4. Down is in through the cage and out the seal ring. (see figure 9).
