BICERA Type Crankcase Over-Pressure Relief Valves
Compressors supplied with optional BICERA type valves, are shipped with standard solid
crosshead guide covers installed to provide a 100% seal and prevent any exchange of
atmosphere during shipping or storage. The BICERA valves are boxed and shipped sepa-
rately. The BICERA valves are to be installed on the compressor crosshead guides just prior
to startup.
• A valve may be placed on any throw by replacing a standard crosshead guide cover,
except when one valve per throw pair is supplied, then each pair of throws is to have
a valve.
• Replacement paper gaskets are provided, if needed. Before installing the valves,
apply an anti-seize lubricant to both sides of new gasket surfaces, when replacement
gaskets are needed. This will ease future removal.
• Tighten cap screws hand wrench tight.
• The crosshead guide covers which are replaced with BICERA relief valve assem-
blies, may be put into the customer’s parts inventory or scrapped as desired.
