Design features
GUIDED BALL VALVE – KITZ ISO T60S
Fire-safe layout:
(1) Prevention of internal leaks
When resistant sealing materials are damaged or destroyed by a fire in a plant, the edges of
and seat retainers Downstream metal tubes preloaded by seat springs contact the ball to close the fluid line and minimize internal leakage through the valve orifice. And KITZ’s original design flexible graphite seat retainer packing rings prevent fluid leakage between valve covers and seat retainers during and after a plant fire.
(2) External Leak Prevention
External leakage from the valve stem area is prevented by double sealing with flexible graphite gland packing rings and O-rings. Leaks through the valve body gasket are protected by flexible graphite gaskets. Even after a fire has damaged the O-rings, the flexible graphite gland packing rings and gaskets remain intact to prevent external fluid leakage.
Tight Shut-off Sealing Mechanism:
Double Block and Bleed Function:
Blowout–proof Ball Seat Assembly:
Antistatic Design:
Cavity Pressure Relief:
Low Emission Guaranteed Design:
Options:
(1) Emergency Seal Restoration
For accidental leakage from ball seats or stemsealing area, a sealant supply mechanism may be provided as an option. Should sealing parts be damaged or decomposed by a fireor other accidental causes, leakage can be temporarily prevented or reduced by sealantinjection into this mechanism.
(2) Special Shell and Trim Materials
(3) Special Sealing Component Materials
(4) Butt-weld Piping Connection
(5) Pipe Pups Welded to Valve Ends
(6) DIB: Double Isolation and Bleed (Double Seal)
(7) Stem Extension
(8) Overlay for Bore and Cavity
(9) Actuation (Pneumatic and Electric)
