Worm gear type fully welded ball valve, fully welded ball valve,ball valve

Overview of Fully Welded Ball Valve:

All-welded ball valves are widely used in various fields. Their stability is beyond the reach of ordinary cast steel ball valves. The service life of all-welded ball valves is much longer than that of cast steel ball valves. All-welded ball valves are widely applied in various pipeline equipment such as urban gas, urban heating, petrochemicals, shipbuilding, steel, pressure regulating stations, and power plants. It can be directly buried underground without the need to build tall valve Wells, reducing the project cost. At the same time, it can also avoid injury to personnel during valve operation and can be reliably used for a long time.

Application of fully welded ball valve:

1. Urban gas: Gas output pipelines, main lines and various branch supply pipelines, etc.

2. Centralized heating: Output pipelines of large-scale heating equipment, main lines, and branch lines.

3. Heat exchanger: Opening and closing of pipelines and various circuits.

4. Steel plant: Various fluid pipelines, waste gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines.

5. Various industrial equipment, various heat treatment pipelines, various industrial gas and heat pipelines.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition

Performance of fully welded ball valve:

It requires no maintenance, adjustment or lubrication, is easy to install, and can operate reliably for a long time at low operating costs. The surface is treated with powder coating technology, presenting a lustrous and beautiful appearance. There will be no external leakage or other phenomena. The installation of the adjustment mechanism is very simple. The operating handle can be removed and installed in the opposite direction.

2. As the valve seat is composed of a carbon fiber reinforced Teflon sealing ring and disc springs, it has a strong adaptability to changes in pressure and temperature, and will not cause any slippage within the marked pressure and temperature range.

3. The processing of the sphere is tracked and inspected by advanced computer detectors, so the processing accuracy of the sphere is high.

4. As the valve body material is the same as that of the pipeline, there will be no uneven stress, nor will it deform due to earthquakes or vehicles passing over the ground. The pipeline is resistant to aging.

5. Integral full welding, equal diameter and variable diameter channels, fixed ball and floating ball, double piston effect sealing system, and automatic injection of sealant type bearings.

6. To prevent static electricity, steel balls and springs are respectively installed between the valve stem and the ball, as well as between the valve stem and the stuffing box. These can maintain the conductivity of all valve parts and the valve body, allowing the current to pass through the area and release static electricity. Not only does it prevent fire, but also corrosion, and achieve temporary cutting to facilitate timely maintenance.

7. The anti-disengagement function of the valve stem is due to the fact that the valve stem is constantly subjected to disengagement force under the influence of the pressure inside the valve. Therefore, the valve stem is designed with an anti-disengagement structure.

8. Use a thrust washer made of low-friction material to support and push the pressure towards the valve stem, so that the valve stem only serves to transmit torque
