STANDARD FEATURES
|
ADVANTAGES
|
|
3-Piece Design
|
In-line serviceable swing-out center section allows easy access to internal valve components without disturbing alignment of pipe. Functions as both valve and union.
|
|
Bottom Entry Live Loaded Stem
|
Self adjusts with pressure and temperature fluctuations. Blow-out proof anti-static design helps prevent accidents and injuries.
|
|
High Cycle Stem Packing
|
PEEK and Nova* thrust bearings and stem seals extend valve cycle life over conventional ball valves and are the best choice for actuation.
|
|
Fully Encapsulated Body Seals
|
Allows valve ends to be welded in line without disassembly, saving costly labor time. Also prevents seal ruptures in high pressure or steam applications.
|
|
Integral Mounting Pad
|
Ideal for actuation. Centering lip feature assures precise alignment of bracket, stem and coupler. Actuators may be retofitted on existing Series 99 without disruption of line integrity. Allows for secondary containment unit to be added when necessary.
|
|
Lockable Handle
|
All Sharpe® Series 99 Valves meet OSHA standards with locking device. Keeps valves from being opened or closed accidentally.
|
|
Slotted Seat Design
|
Relief slots help equalize body pressure, reduce torque and assure leak-tight sealing. Seats also provide a wiping action that cleans ball and seats each time valve is cycled.
|
|
Choice of Seats and Seals
|
A wide variety of seat and seal materials are readily available for the most demanding applications, including Buna, Delrin, Nova*, PEEK, EPDM, Viton®, TFE, RTFE, TFM®, Garfoil, and UHMWPE.
|
|
Variety of End Combinations
|
A wide choice of optional end connections are available including, but not limited to threaded ends, socket weld ends, butt weld ends, flush bottom tank pads, flanged ends.
|
|
Floating Ball Design
|
Precision engineered solid stainless steel ball with relief hole in stem slot prevents build up of cavity pressure while valve is in open posistion. Bi-directional floating ball seats downstream reduce torque and guarantee a bubble-tight shut off.
|
|
Encapsulated Body Bolts
|
Heavy duty stainless steel bolting is protected from outside enviroment assuring valve integrity.
|
|
Traceability
|
Heat numbers are provided on all valve bodies and ends. CMTR's (certified mill test reports) are available upon request.
