INSULATION GLOBE VALVE

INSULATON GLOBE VALVE

BJ45H/Y-15-40C/P/R

Product overview

Insulation globe valve is the most widely used type of valve. Its popularity is due to the low friction between the sealing surfaces during the opening and closing process, which is relatively durable, has a small opening height, is easy to manufacture, and is easy to maintain. It is not only suitable for medium and low pressure, but also for high pressure. Its closing principle is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc with the sealing surface of the valve seat, preventing the flow of the medium.

The insulation shut-off valve only allows one-way flow of the medium and has directionality during installation. Its structural length is greater than that of a gate valve, and at the same time, it has high fluid resistance. During long-term operation, its sealing reliability is not strong.

Insulation globe valve are divided into three categories: straight through, right angle, and DC inclined globe valves.

Product advantages

1. The structure is simple, and manufacturing and maintenance are relatively convenient.

2. Small work schedule and short opening and closing time.

3. Good sealing performance, low friction between sealing surfaces, and long service life.

Product defect

1. The fluid resistance is high, and a large amount of force is required for opening and closing.

2. Not suitable for media with particles, high viscosity, and easy coking.

3. Poor regulation performance.
