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 confined 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.
Back-Seat Bushing Gland can be Re-packed in-situ Spherical body with large radius, allows stressand turbulence to be minimised
Range of materials to suit Pressure Classes
Valves are supplied with plug type disc as shown
Seat ring is seal welded to eliminate potential leak paths.
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.
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.
Packing contains corrosion inhibitor to avoid stem pitting. Deep stuffing box design ensures long packing life.
