Product Description

Globe valve  (TH-GBV)

The globe valve is a tool that relies on the pressure of the valve stem to make the sealing surface of the valve flap closely fit the sealing surface of the valve seat to prevent the flow of media. It is a forced seal valve and is one of the most widely used valves.

According to the direction of the channel, the globe valve is divided into four types: straight-through globe valve, direct current globe valve, angle globe valve, plunger globe valve.

The structural length of the globe valve is greater than that of the gate valve, and at the same time, the fluid resistance is large. During long-term operation, the reliability of the seal is not strong.

Area of application

Marine industry, Water supply & drainage, fire fighting, shipbuilding, water treatment, power stations, energy, food, chemical, and other systems

Globe valve features

  • The structure of the globe valve is simpler than the gate valve, and it is more convenient to manufacture and maintain.
  • The sealing surface is not easy to be worn and scratched, with good sealing performance and long service life.
  • When opening and closing, the flap travel distance is small
  • The opening and closing torque is large, the opening and closing is more laborious, and the opening and closing time is longer.
  • Large fluid resistance and large power consumption.
  • The valve flap is often eroded when fully opened.

Disadvantages

  • The fluid resistance is large, and the force required when opening and closing is large.
  • It is not suitable for medium with particles, high viscosity and easy to coking.
  • Poor adjustment performance
