Oil States Piper Valve Series DC Drilling Diverter ball valves are designed to provide superior
performance and allow for extended life in corrosive and abrasive drilling fluid service.
This design philosophy is not found in traditional trunnion mounted pipeline ball valves.
The compact design allows for easier handling and installation in tight areas found in rig structures.
Series DC valves are available in sizes from 10″ thru 18″ in ANSI Class 300, 600 and 900.
Series DC Diverter valve
Series DC Diverter Valves are used in:
- Diversion Flow Lines (NPS 8″ thru 18″)
- Fill-up Valves (NPS 2″ thru 12″)Trip Tank Valves (NPS 2″ thru 12″)
- Motion Compensation Control Valves (NPS 1″ thru 10″)
- Tensioning System Control Valves (NPS 1″ thru 10″)
- Riser Booster Line Valves (NPS 2″ thru 8″)
- ANSI Class 300, 600, 900, 1500 and 2500
- API 5000 and 10000 pressure classes
SERIES DC APPLICATIONS
- External stroke adjustment allows setting for the full open position,without disassembly of the actuator.
- Unique seat assembly design provides excellent low-pressure sealing capability.
- All valve bodies and retainers are internally Xylan® coated as a standard to provide corrosion resistance for ease of disassembly and extended life.
- Valve bores are sized to match Schedule 80, 100 or 120 inside diameters to eliminate any transitions that could be an erosion point during flow.
- Large seat contact area provides positive sealing even in high particulate conditions. Seat carriers are salt bath nitride QPQ finished as a standard.
- Ends are available in a compact BFW or RTJ flange
- Line spread required for body group removal is less than 4″ when using Piper compact BFW ends.
- Easy access lifting points are located at several places on the valve body as well as on the end flanges.
- Visual position indication is standard. Optional position indication includes electric, pneumatic and hydraulic.
- Hydraulic double-acting actuators are standard. Remote operation and spring return options are available.
- Floating ball design results in fewer parts, lower repair kit costs and a truly field-repairable valve.
- Seat insert is not captured and can be replaced without replacing the entire seat assembly.
- Field Repairable: Floating ball design allows for true field repair that can be accomplished in hours, not days.
- Interchangeable Parts: Internal parts are completely interchangeable between ANSI 300, 600 & 900 series valves of the same bore size.
- Compact Size: Compact valve design is almost half the size and weight of a standard API 6D trunnion mounted ball valve.
- Fewer Parts: The number of internal parts on a “DC” ball valve is less than half of the parts in conventional trunnion ball valves, resulting in less expensive repair kits.
- Available in 10″ thru 18″ sizes.
- ANSI Class 300, 600 and 900.
- Wide range of materials available to suit a variety of application requirements.
- Offered in 2″ thru 8″ sizes for fill-up,
trip tank and booster line applications. - Actuator packages available with
a variety of position indicator options. - Materials available for H₂S service.

SERIES DC FEATURES
Series PB Ball Valves
Designed, engineered and built for performance
Workhorse of the Piper Manifold System
BUILD YOUR MANIFOLD LIGHTER, SMALLER, SMARTER.
Start saving the weight, space and money when building manifold systems. See the illustrated comparison below between a conventional 6″ ANSI 1500 full port trunnion ball valve with flanged end connections including companion flanges, and a Piper Series PB 6″ nominal ANSI Class 1500 valve.
Dimensional & Weight Comparison
- Total weight is 70% less.
- Total length is 43% less.
- Relative height to bonnet is 28% less.
-
SERIES PB VALVE DESIGN BENEFITS
-
Piper’s Optimum-Flow Technology: Maximum-Flow bore sizes are offered that correspond to the inside diameters
of ASTM A106 Grade B pipe, reducing or completely eliminating transition areas and thereby minimizing system friction pressure loss. -
Minimal line spread required for easy removal from service.
-
Modular 3-Piece design provides multiple end connection options.
-
Compact design occupies up to 50% less space than conventional flanged-end ball valves for skids or manifolds. (See right)
-
Series PB Check Valves
Positive, System Backflow Prevention
Fitting connection
Direct connection
- Swivel Flange Connections offer the benefit of fast, easy installation or removal of all Series PB valves
- For even greater space and weight savings, smaller size check valves can be bolted directly to the ball valve body as shown here
Permanent Service Subsea Valves
Designed for 30 year Submerged Service
Oil States Piper Valve Series MST Permanent Service Subsea Metal-Seated Ball Valves offer the following features:
- Tungsten Carbide Overlay on ball/seat mating surfaces, lapped to each other for positive sealing.
- Internal Trunnion Blocks reduce the size and weight of the valve, and the number of external seals.
- Double Block & Bleed Design for testing seat integrity prior to installation.
- Double Metal Barrier Seals employ Z-ring technology on all external connections.
- Optional Anti-static Design
