Provision for
automatic drainage is sometimes not included
in the original system. It is possible to
discharge liquid manually through a valve
that has been cracked open. However, an open
drain also continuously wastes air or gas.
Periodically opening a valve by hand and
leaving it until it blows freely will also
drain a system. Frequently, however, an
operator will delay or forget to close a
valve, thereby wasting precious air or gas.
Liquid drainers
installed at appropriate points will remove
liquid continuously and automatically
without wasting air or gas. In addition to
drainage of the system, liquid drainers
should provide:
- Trouble-free
operation with minimal need for
adjustment or maintenance
-
Reliable operation
even in the presence of dirt, grit and
oil
-
A long operating life
-
Minimal air loss
-
Ease of repair
