Parker Autoclave Engineers ball valves can be utilized to switch or isolate flow. The standard material of construction of the valve is 316 cold worked stainless steel with PEEK seats, graphite filled PTFE stem seal, and o-ring material as required by the process fluid.
The subsea ball valve design incorporates additional o-ring seals, which prevent the ingress of seawater into the valve which would adversely affect the operation of the valve as well as contaminate the process fluid. A significant feature of the subsea design is a thrust washer positioned under the stem preventing outside sea water from moving the stem from it’s aligned position.
Subsea ball valves are designed to facilitate operation by a Remote Operated vehicle (ROV). ROV operator assemblies are used for valve mounting and to provide positive stopping for precise 90° operation.
Various tube and pipe connections are available throughout a variety of valve configurations with standard port sizes from 3/16” to 1”. Contact Parker Autoclave Engineers technical sales support or your local distributor for more information on optional materials of construction, seal materials and ROV operator designs to fit your application requirements.

Maximum temperature rating is determined by the o-ring material (see descriptions below).
Maximum pressure rating is determined by the end connection (see table above).
Note: Side inlet pressure not recommended. Bottom inlet pressure only.
NOTE: Ball valves are not recommended for critical gas applications such as Hydrogen, Helium or other small molecular gases.
