Gear Operated Globe Valve

Gear Operated globe valve designed and manufactured to provide maximum service life and dependability. All globe valves are fell ported and meet the design requirements of American petroleum institute standard API600,BS EN13709 and generally conform to American society of mechanical engineers standard ASME B16.34, valves are available in a complete range of body/bonnet materials and trims.

The stems of gear operated globe valves are forged one piece and ACME threaded, then mechanized and finally provided with a smooth finishing in order to minimizing the friction.

Body and bonnets are high quality cast and afterwards precisely machined, directing the attention to prevent stress concentration.

Bonnets are made either of one piece only-the yoke then being an integral part of it-or have two pieces, depending on the size of the globe valve. This ensures the perfect alignment with the body what leads to an accurate opening and closing.

Bodies of globe valves are designed considering the same characteristics as gate valves, which in this case means that disc is guided in bigger valve sizes or high pressure service in order to avoid vibrations and better seat.

Design Features

Design standard as per: BS1873､GB/T 12235

Generally, lift is just 1/4 of the valve seat port, ensuring a short Opening/closing time. 
Only one sealing face exists on the valve body and disc.

The valve is designed as a back seat sealing structure.

Use flexible and woven graphite collaboration type packing.
