Globe Valves

Product Description :

A globe valve, different from other Valves, is a type of Valves used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. A Globe Valves is a linear motion Valves and are primarily designed to stop, start and regulate flow. The disk of a Globe Valves can be totally removed from the flow path or it can completely close the flow path.

Principal Operations: :

Conventional Globe Valves may be used for isolation and throttling services. Although these Valves exhibit slightly higher pressure drops than straight=through Valves (e.g., gate, plug, ball, etc.), they may be used where the pressure drop through the Valves is not a controlling factor. [Because the entire system pressure exerted on the disc is transferred to the Valves stem, the practical size limit for these Valves is NPS 12 (DN 300). Globe Valves larger than NPS 12 (DN 300) are an exception rather than the rule. Larger Valves would require that gigantic forces be exerted on the stem to open or close the Valves under pressure. Globe Valves in sizes up to NPS 48 (DN 1200) have been manufactured and used.

Globe Valves Advantages :

• Good shutoff capability.
• Moderate to good throttling capability.
• Shorter stroke.
• Available in tee, wye, and angle patterns, each offering unique capabilities.
• Easy to machine or resurface the seats.
• With disc not attached to the stem, Valves can be used as a stop-check valve.

Product Range :

Globe Valves are precisely designed to control flow. The range of flow control, pressure drop, and duty must be considered in the design of the Valves to avert premature failure and to assure satisfactory service. Valves subjected to high-differential pressure-throttling service require specially designed Valves trim.
