STANDARD FEATURES
|
ADVANTAGES
|
|
ASME B16.34 Design
|
Full port (Schedule 160) 3-piece bolted body design meets all requirements of ASME B16.34 for Class 2500.
|
|
NACE MR0175 Compliance
|
Standard materials of construction have been selected, inspected, and tested to provide compliance with NACE MR0175. Standard bolting is suitable for Non-exposed services.
|
|
Blow-out Proof, Heavy-duty Stem
|
The internal-entry stem is machined with a heavy shoulder to prevent blowout, and is 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 for proper compression through the full metal-to-metal contact joint design, eliminating seal extrusion and potential body joint leakage.
|
|
Integral Mounting Pad
|
Permits easy field conversion from manual operation to power actuation.
|
|
Locking Handle
|
All Sharpe Series 60 ball valves supplied with lever handles are designed to permit locking the valve in either the open or closed position.
|
|
Slotted Seat Design
|
Relief slots are provided around the perimeter of the seats to allow equalization of pressure in the body cavity with the upstream line when valve is closed, preventing upstream seat extrusion and enhancing downstream sealing performance.
|
|
Choice of Seats and Seals
|
A choice of seat materials is available for the most demanding applications. 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 open.
|
|
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.
