Globe Valve

A Globe valves is a linear motion valve and are primarily designed to stop, start and regulate flow. The disk of a Globe valve can be totally removed from the flow path or it can completely close the flow path.

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 valve is not a controlling factor.

The globe valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction, resulting in greater resistance to flow, causing high pressure drop. The globe valve is an excellent valve to use in high pressure operation of steam. Our globe valves are factory-made with quality material for long term use.

Advantages and disadvantages of Globe valves

ADVANTAGES:

Good shutoff capability

Moderate to good throttling capability

Shorter stroke (compared to a gate valve)

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, valve can be used as a stop-check valve

DISADVANTAGES:

Higher pressure drop (compared to a gate valve)

Requires greater force or a larger actuator to seat the valve (with pressure under the seat)

Throttling flow under the seat and shutoff flow over the seat
