| STANDARD FEATURES |
ADVANTAGES |
| Fire Safe - API 607 4th Edition |
Series FS50 flanged valves
have been qualified by testing to API Standard 607, 4th
Edition. The valve design incorporates a secondary metal
seat in the body, providing the required shutoff should
the seats be destroyed by fire. |
| ASME B16.34 Design |
Full port, split body design
meets all requirements of ASME B16.34 for Class 150, 300,
and 600 ball valves. |
| Blow-out proof, Heavy-Duty
Stem |
The internal-entry stem is
machined with a heavy shoulder to prevent blowout. All
Class 600 stems are machined from high-strength 17-4PH
stainless steel as a standard material. |
| Anti-static Configuration |
Anti-static devices are included
at two points on the valve stem to provide continuous ball-to-stem
and stem-to-body grounding, to prevent build-up of static
charge in the valve, and potential sparking conditions. |
| Live-loaded Stem Seals |
Stem seals are live-loaded
using Belleville springs to provide consistent sealing
forces, reducing or eliminating the need for frequent seal
adjustment. |
| Fully Encapsulated Body Seals |
Provides consistent and controlled
loading of the body seal compression through a full metal-to-metal
contact joint design, eliminating seal extrusion and potential
body joint leakage. |
| Integral Mounting Pad |
Ideal for actuation. ISO 5211
mounting dimensions simplify fit and alignment between
valve, bracketry, and actuator. Permits easy field conversion
from manual operation to power actuation. |
| Latching/Locking Handle |
All Sharpe Series 50 ball valves
supplied with lever handles are designed to permit locking
the valve in either the open or closed position. Sizes
through 2" are supplied with a slide latch engaged at open
and closed positions to prevent inadvertent operation. |
| Slotted Seat Design |
Relief slots are provided at
the perimeter of the seats to equalize pressure in the
body cavity with the upstream line when valve is closed,
preventing upstream seat extrusion and enhancing downstream
seating performance. |
| Choice of Seats and Seals |
A variety of seat materials
is available for the most demanding applications, including
TFE, RTFE, TFMTM and NOVA. Stem packing and body seals
are die-formed flexible graphite. |
| Floating Ball Design |
Precision engineered and machined
solid stainless steel ball with relief hole in the stem
slot prevents build-up of cavity pressure while the valve
is in the open position. |
| Material Traceability |
Body and end piece castings
are marked with heat codes providing traceability to the
chemical analysis and material test reports performed at
the foundry. CMTR's (Certified Material Test Reports) are
available upon request. |
| Fugitive Emissions Testing |
Sharpe Ball Valves have been
tested in accordance with ANSI/ISA-S93.00.01-1999 for fugitive
emissions, which includes thermal cycling as well as mechanical
cycling, and achieved a Leak Rate Category of 75 PPM. Details
of testing, and test reports or certifications are available
from on request from Sharpe Valves. |
