Low Pressure Umbilical Supply
Valves / Cross-Connect Valves
Overhaul
The quarter turn valves used for the LP cross
connect and umbilical supply are very reliable,
and require only minimal maintenance.
The valve is made of 316 stainless steel, and have
a rated working pressure for the XLDS of 400 psig.
The valve should be overhauled at least every five
years, or whenever the valve does not operate
smoothly, or if any leakage occurs. The valve is
simple to disassemble and service, however, the
person
performing
service
must
be
knowledgeable and properly trained. The cross-
connect valve and the umbilical supply valve, use
the same components, except for the nylon
locking nuts. Overhaul is done in the same
manner.
NOTICE
Make sure the top washer (14), has the
tapered hole bevel facing up, for smooth
engagement to the stem (16).
