Cast Steel Globe Valve

Cast Steel Globe Valve

ONERO offers a broad line of Cast & Forged globe valves in both Straight Through and Angle Pattern. Size ranges from 1/2” to 36”, Pressure ratings from Class150 to Class2500, which can be your best choice for the applications of throttling and regulation in most cases. Globe valves have several types of designs: globe, angle, Y-pattern, T-pattern, etc.

 Application

A complete range of globe valves, ideal for throttling and shut off services for oil & gas, petrochemical, power, offshore and other demanding applications. Designed for duties where high flow efficiency, tight shut-off and long service life is a prime requirement.

Globe valves

ONERO Globe valve uses a disc-type/plug, which is always in the path of the flow, to regulate the flow volume; this process is called throttling.

A Globe can also be used as a stop valve (for starting and stopping flow).

Globe Valves : High Pressure Seal Globe Valve

ONERO high pressure seal globe valve’s top and bottom-guided disc assures stem operation without side thrust caused by high pressure flow. The non-rotating stem results in lower friction of all moving parts and longer stem packing life. All this resulting in smooth, easy operation and tight shutoff under extreme pressures.

 Application

The high pressure seal valves are designed in accordance with BS1873 and ASME B16.34 for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service.
