High Quality Industrial ASME B16.34 globe valve China factory
What's ASME B16.34 globe valve ?
ASME B16.34 globe valve is one of the most popular design of globe valves,for US and API system.the inside diameter,materials,the face to face,wall thickness,pressure temperature,are are defined by ASME B16.34.
In addition,depending on the design of the seat and disc, the seating load of ASME B16.34 globe valve can be positively controlled by a screwed stem.
the ASME B16.34 globe valve can be used for throttling purposes as well.Many single-seated valve bodies use cage or retainer-style construction to retain the seat-ring, provide valve plug guiding, and provide a means for establishing particular valve flow characteristics. it can also be easily modified by change of trim parts to change the flow characteristic or provide reduced-capacity flow, noise attenuation, or reduction or elimination of cavitation.
ASME Globe Valve Body Patterns,there are three primary body patterns or designs for Globe valves, namely:
- 1).Standard Pattern (also known as Tee Pattern or T – Pattern or Z – Pattern)
- 2).Angle Pattern
Working Principle oASME B16.34 globe valve
A globe valve is comprised of a movable disc and a stationary ring seat in a spherical body. The seat of a globe valve is in the middle of and parallel to the pipe, and the opening in the seat is closed off with the disc. when the handwheel is rotated manually or by an actuator, the disc movement is controlled (lowered or raised) by means of the valve stem. When the globe valve disc seats over the seat ring, the flow is completely stopped.
Main feature of ASME B16.34 globe valve
- 1).Good sealing capabilities
- 2).Short travel distance of the disc(stroke) between the open and closed positions,ASME globe valves are ideal if the valve has to be opened and closed frequently;
- 3).The ASME globe valve can be used as a stop-check valve by modifying the design slightly.
- 4).There is wide range of capabilities as available in tee, Wye, and angle body styles.
- 5).Easy Machining and resurfacing of the seats,for various purposes.

Application of ASME B16.34 globe valve
ASME Globe Valve is widely used in a wide range of services; both low pressure and high pressure fluid services. The typical applications of globe valves are:
- 1).Designed for frequent on-off pipeline,or throttling the liquid and gaseous medium
- 2).Fluids:Water, steam, air, crude petroleum and petroleum products, natural gas, gas condensate, technological solutions, oxygen, liquid and non-aggressive gases
- 3).Cooling water systems requiring flow regulation.
- 4).Fuel oil system requiring leak-tightness.
- 5).Control valve bypass systems.
- 6).High-point vents and low-point drains.
- 7).Oil and Gas, Feedwater, chemical feed, Refinery, condenser air extraction, and extraction drain systems.
