CAST STEEL GLOBE VALVES
CAST STEEL GLOBE VALVES
KVC (UK) LTD Globe valves are manufactured to API Std.600 and tested to BS 1873, B16.34 and tested to API Std.598
Globe Valves are used where throttling and shut off are required. They can also be used for on-off service, but due to high pressure drop, this is generally confi ned to applications where the valve is normally closed and pressure drop is not important when the valve is open. Close throttling can lead to altered velocities, this leads
to excessive noise and vibration which can damage the valve or piping system.
BODY AND BONNET
Back-Seat Bushing
Gland can be Re-packed in-situ
Spherical body with large radius, allows stress and turbulence to be minimised
BODY-BONNET JOINT / GASKET
Range of materials to suit Pressure Classes
DISC
Valves are supplied with plug type disc as shown
WELDED-IN SEAT RING
Seat ring is seal welded to eliminate potential leak paths.
STEM
One piece stem, forged tee-head connection
Rolled or cut ACME threads subject to valve size
Polished on the packing contact area
Ensures long life & optimal tightness
Engineered stem break-point above packing area
Ensures sealing integrity to atmosphere.
GLAND
The Gland Flange & Packing Gland are manufactured in two separate pieces
Adjustable gland in service
Optional live loaded gland can be specified
Backseated design allowing the gland packing to be replaced in situ.
STUFFING BOX
Packing contains corrosion inhibitor to avoid stem pitting.
Deep stuffi ng box design ensures long packing life.
