By-Passes

A By-Pass can be used to equalize pressure at inlet and outlet before opening main valve; facilitates
easy valve operation. Can also be used for preheating outlet lines and eliminate damage from too fast
expansion. The built up type By-Pass is available on all NIBCO iron valves and is attached in accordance
with MSS By-Pass and Drain Connection Standard SP-45. The By-Pass valve used on standard iron valves
is a globe valve. Specify by adding (Z) to Fig. No, i.e. F-000-Z.
