Three different temperature rated ball-type service valves are available for use with
Metal Samples retrieval tools:
standard, low and high temperature. The female threads on this valve are industry-standard
ACME threads and may be used with any Metal Samples Corrosion Monitoring Systems high
pressure access fitting as well as any other 2" access fitting. The valves have a
bleed valve located on the non-process side of the ball. This bleed valve may be used to
drain the retrieval tool, sample process, or be used as a path for back-pressuring. All
valves are NACE MR0175 compliant for use in sour service, factory pressure tested for a
working pressure of 6000 psi W.O.G..
The service valve is a portable valve that is used in conjunction with a retrieval
tool. The service valve is threaded onto an access fitting in preparation for retrieving a
plug. Next, the retrieval tool is attached to the service valve. System pressure is then
equalized in the retrieval tool by unseating the plug.
Metal Samples standard service valve is constructed from A350LF2. We also offer a severe service option in 17-4PH. Please contact us for additional details. |

Occasionally deposit buildup in
access fitting bodies does not allow for pressure equalization through the plug. If this
occurs, the retrieval tool can be back pressured by use of a back-pressure kit (P/N -
HA104000). Once pressure equalization has occurred, the plug is removed and the valve is
shut. Finally, the retrieval tool is removed from the valve allowing access to the plug
and its accessory. A Blanking Cap/Plug Assembly (P/N - PS5612) may be installed on the
valve as an additional safety measure, if required.
Service valves are supplied with a durable lightweight field service case, extension bar, tool kit, and one O-ring seal kit.
