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.
|
|
Live Loaded High Cycle Stem
|
Two belleville washers in actuated valve allow the valves to perform exceptionally during high cycling and in control applications.
|
|
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 retrofitted on existing series FS 84/99 without disruption of line integrity. Allows for secondary containment unit to be added when necessary.
|
|
Lockable Handle
|
All Sharpe® Series FS 84/99 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
|
A wide variety of seat materials are readily available for the most demanding applications, including Nova*, PEEK, TFE, RTFE, and TFMTM. Stem packing and body seals are Grafoil.
|
|
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, grooved ends and 150#/300# flanges.
|
|
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 position. Bi-directional floating ball seats downstream reducing torque and guaranteeing a bubble-tight shut-off.
|
|
Encapsulated Body Bolts
|
Heavy duty stainless steel bolting is protected from outside environment assuring valve integrity.
|
|
Traceability
|
Heat numbers are provided on all valve bodies and ends. CMTR's (Certified Mill Test Reports) are available upon request.
|
|
Fire Safe API 607 4th Edition
|
A metal centering ring is part of the end cap that fits into the body (tongue and groove) and aligns the pipe end with the ball. During fire, the seat is destroyed and the ball moves downstream where it makes contact with a special shaped end that provides a secure fire tight seal.
