SHARPE Series 80/89 Ball Valves

High Performance 3 Piece Ball Valves

SHARPE Series 80/89 Ball Valves

The Series 80/89 full port 3-piece ball valves are designed for high performance, long cycle life and exceptional durability.  These ball valves are fully compliant to API 608 class 800 for sizes 1/4″ to 2 1/2″ and class 300 for sizes 3″ to 4″.  They feature enhanced performance and design flexibility.  The Series 80/89 ball valve is generally used for petroleum refining, chemical & petrochemical processing.

SHARPE Series 80/89 High Performance 3-Piece Ball Valve
  • 3000 WOG
  • Blow-out Proof Stem
  • Live Loaded Stem Packing
  • ISO 5211 Mounting Pad
  • Locking Devices
  • 5-Seat Design
  • ASME B16.11 Threaded Ends

Extensions, brackets and auxiliary options

End connection combinations

  • A wide selection of optional end connections are available, including, but not limited to: threaded, socket weld, butt weld, extended butt weld and flanged ends to class 150, 300 and 600.

Cast mounting brackets

  • Cast brackets all in stainless steel material with hole patterns conforming to ISO 5211 on top and bottom planes for actuation mounting.
  • Optional safety locking holes for securing valves during maintenance.
  • Wide tool clearance for installation, aesthetic design and open visibility.

Extension bonnets

  • Extensions – an option to move the valve top interface away from the pipe line for insulation and reduction of heat transfer.
  • Emission bonnets – an added stem sealing system for valves without integral emission ports.
  • Cryogenic bonnets – valves for cryogenic service are converted to accept a cryogenic extension bonnet with an extended stem, to distance the stem sealing area away from low temperatures.

Additional options

  • Steam jackets – enables the valves to be kept at a controlled temperature.
  • Diverters – valves that are converted for diverting or mixing applications that usually require two valves.
  • Tank bottom valves – valves with special end caps welded directly to tanks or pipes, to eliminate the dead volume that is common with standard fittings.
  • Locking device – Sharpe exclusive, tamper-proof locking device is spring loaded, and ensures lock is always activated.
  • Spring return handles – ensures that the valve cannot be left open (or closed). Can be retrofitted on-site without valve disassembly.

Rugged body and end caps

  • Rugged body with higher and deeper stem packing area to allow for more seals.
  • Two-cast bosses for optional fugitive emission ports (patent pending)
  • Larger ISO bolt pattern for handling higher valve torques.
  • End caps with extra thick flanges to comply with class 800.

Tongue and groove design

  • Fully encapsulated body seals, allowing ends to be welded in-line, without time consuming and labor intensive disassembly.
  • In the event of fire, this design will compensate for bolt expansion and reduce the chance of external leakage.
  • Helps prevent seal ruptures in high pressure, cryogenic or steam applications.

Heavy duty stem design

  • Stem diameters have been increased to meet the higher torque requirements of the most demanding applications.
  • Stem-to-ball contact area is wider and larger, allowing the valve to be used for higher torque applications.
  • Design allows for the use of stainless steel stem material rather than 17-4PH, and offers superior corrosion resistance.
  • All stems have a Double-D configuration to indicate ball position.

 Body bolt design

  • Larger diameter body bolts to comply with class 800.
  • Encapsulated body bolts for added protection and wash down applications.
  • Optional bolts and nuts to comply with NACE MR0175/ISO 15156.

 ISO 5211 top-works compatibility

  • The top-works offer compatibility for mounting a
    wider range of accessories.
  • Actuators and Sharpe accessories may be retrofitted
    on existing valves without disruption of line integrity.

 Floating ball design

  • Solid stainless steel ball with wide selection of configurations for a variety of applications for diverting, mixing, controlling, flushing, purging and more.
  • Floating ball seals on the downstream seat, reducing torque and guarantees bubble-tight shutoff.

 Unique “SharpeGrip” handle

  • The “SharpeGrip” is a unique cast, stainless steel handle with special design to accommodate locking devices.
  • The handle length is according to API 608 requirements and withstands higher valve operating torque.
  • A comfortable, ergonomic hand-grip design.

Operational flexibility and process compatibility of stem assemblies

Stem assemblies

  • STANDARD – a multiple pack of chevron “V” shaped stem seals for better sealing in PTFE, TFM® or Nova materials.
  • FIRE SAFE – double pack of flexible graphite seals for sealing under fire conditions.
  • FUGITIVE EMISSION – 2-pack stem seals in PTFE or graphite, with lantern ring to allow leak detection through the emission ports.
  • HIGH-CYCLE – unique designs for demanding high cycle applications that consist of multi-system sealing devices in the stem bonnet.

Stem sealing

    • Double containment stem packing with threaded ports to connect sensors.
    • Allows for a range of sealing combinations for severe applications and other stringent design demands.
    • Two pairs of concave and opposing spring washers provide additional compensation for seal wear.
    • Self-adjusts with pressure and temperature fluctuations.
    • Blowout proof stem design with anti-static device ensures the stem cannot be blown out by accidental medium pressure rise or cause ignition.
    • PEEK and Nova thrust bearings and stem seals extend valve life-cycle, and are the perfect choice for actuation applications.

Seats and seals

A wide range of seat and seal materials are readily available to meet the most demanding applications including:

Buna, Delrin®, Nova, PEEK, EPDM, Viton®, PTFE,
RTFE, TFM®, Grafoil, UHMWPE.

Seat designs

All the seats are designed with circumferential relief slots to equalize body pressure, reduce torque and assure leak-tight sealing.
Aside from standard seats, Sharpe also supplies numerous seats designated for specific applications, including, but not limited to:

    • Seats that eliminate the voids in the valve body cavity to minimize solidification of the media.
    • Seats used in diverting or mixing applications where the flow plan governs seat type.
    • Metal seats are the only option where high temperatures, severe abrasion and corrosive fluids are involved.
    • Seats designed to relieve pressure build-up in the body cavity.
    • Seats with O-rings to enable shutoff on upstream and downstream.
