2 Maximum flow rate is based on minimizing erosion rates when using typical fluids. Erosion rates may vary based on fluid
contents. Please regularly inspect MSV internals and wear surfaces indicated in operation manual.
3 Ratings provided represent design intent. These values may change pending outcome of design verification testing.
4 Value calculated based on 1200 kg/m
3 density, 60 s/L viscosity working fluid at maximum rated flow rate. Does not
include pressure drop induced by CRT or casing seal.
5 Circulation pressure is generally governed by packer cup pressure capacity. Pressure capacity may be less than
indicated if alternative seal arrangements are used or end load is exceeded.
6 Provision for 500 ton CRTi2-8.63 end load capacity is available upon request. Maximum MSV diameter will increase
to 6.33 in.
7 Does not consider CRT or casing seal assembly.
8 MSVe1-4.5 is housed entirely within CRTe body and does not add any length to CRT assembly.
Mudsaver Valve (MSV ™ ) 1
Volant’s MSV adapts to the Casing Running Tool with either internal grip (CRTi ™ )
or external grip (CRTe ™ ) architecture. The MSVi ™ is designed for internal grip
and MSVe ™ for external grip tools. Installed between the CRT and casing seal,
the MSV is designed to entirely stop fluid flow after fluid circulating or casing
running operations. The valve opens with applied pressure when circulating
begins, and closes when it is stopped. The MSV allows back flow and will not
trap pressure in the casing string.
The MSV has been designed to the same flow rate limit of each corresponding
CRTi and CRTe 3 .
