Globe valves are extensively employed to control flow. The range of flow control, pressure drop, and duty must be
considered in the design of the valve to avert premature failure and to assure satisfactory service. Valves subjected
to high-differential pressure-throttling service require specially designed valve trim.
Generally the maximum differential pressure across the valve disc should not exceed 20 percent of the maximum
upstream pressure or 200 psi (1380 kPa), whichever is less. Valves with special trim may be designed for applications
exceeding these differential pressure limits.
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
Packing Details:
We choose suitable wood cases according to different valves and arrange skilled workers to pack in case of bruise. Long term cooperated forwarder will book space, clear customs and transport for us without delay. There are three ways for transportation, by sea, by air and by train. We will arrange transportation according to customers' needs.
Delivery Details: According to the order, 7~60days
