3.10 Bypass
If it is essential to maintain a constant supply of steam across the valve. It may be necessary to install a bypass
to ensure continuation of supply when the reducing valve is being serviced Figure 4 and Figure 5.
The bypass valve will normally be the same size as the reducing valve. The handwheel should be padlocked
to prevent unauthorised use, and when in use should be under constant manual supervision.
The bypass may be arranged above or to the side of the main assembly but never below it.
