Fully Welded Self-filtering Ball Valve with Inner Strainer

One  Piece Body self-filtering fully welded Ball Valve with Inner Strainer

Technology Background

In the transmission pipeline of fluid media, the ball valve is an effective and necessary cutoff device. In order to remove the impurities and dirt from the fluid media and keep the transmission pipeline clean and unblocked, a filter set in the transmission pipeline is an essential and important equipment to improve the fluid quality. At the moment, filter and ball valves installed in the transmission pipeline take a large space and are often restricted by application conditions and it’s difficult to remove and wash the filter.

This new practical self-filtering Fully welded ball valve solves the existing problems such as restriction of installation conditions on the setting of filters in the pipeline, the cleaning difficulty during the maintenance, etc. Its reasonable design, compact structure, flexible labor-saving operation, quite convenient installation and maintenance not only obviously reduce the occupied space, but also are good for the cost reduction and wide promotion and application.

Under the opening state of self-filtering fully welded ball valve, when the fluid media passes the inner through-hole cavity of the ball, it can be filtered by the filter network st by its own. When the ball is rotated 90 degrees clockwise, the self-filtering welding ball valve will be in the closing state playing the role of cutting off the fluid media in the transmission pipeline.

On the side wall of the valve body, the connected mid-flange and the drain pipeline connected with the cleaning water pipe are st. It’s able to clean the filter network conveniently and quickly by opening the mid-flange cover and the drain pipeline. It can also set an electric valve or pneumatic valve in the drain pipeline in order to realize the self-washing of the filter network. If the filter network is broken, it’s able to exchange by opening the mid-flange cover.

Technical Features of self-filtering fully welded ball valve

1. With the integrated welding structure, there will be no external leakage problem.
2. The valve seat is constituted by carbonized Teflon seal ring and spring with strong ability to adapt pressure and temperature changes. Within the standard pressure and temperature range, there will be no leakage.
3. The manufacturing process of the ball is traced and tested by the advanced computer detector. The ball has high manufacturing density.
4. The seal ring adopts C-PTFE Material with 20% Carbon to guarantee no leakage at all.
5. Compared with similar products or products of the same specification, the valve body is small and light with a beautiful appearance and long service life.
6. The valve body, ball and side valve body all adopt seamed steel pipes molded by pressing. At the valve rod, use the double O-Ring for seal with the blow-off resistant function.
7. The filter network and the ball combine as one. The link of the ball of filter network itself plays a role of filtering in the pipeline and can replace the filter, achieving the effect of one valve with multiple functions. Therefore, it’s able to save the installation space of pipeline and the business cost and stop impurities with a diameter of greater than 4.5mm.
8. The filter network adopts the V-Shaped Port to guarantee the normal pass of media in the case of blocking impurity particle, while the valve can work normally. It adopts the pressure relief valve design which can adjust the internal and external pressure difference of the valve and improve its security performance. Meanwhile, it’s able to replace the pressure relief valve with a threaded ball valve to make the operation time-saving, labor-saving, convenient and flexible.

Goole Self-Filtering Fully Welded Ball valve, a valve with multiple functions, plays the role of not only media-cut-off but also filtration. So the installation space is saved and it’s able to omit the traditional front filter. The installation is clean, simple and convenient. With the fully welded structure, the service life is longer.

Parts Name and Material of self-filtering fully welded ball valve

The Unique Design for the Inner Strainer of self-filtering fully welded ball valve

1. Design of traditional filter.  

 When impurity particles are cut off in the whole filter, media will be seriously blocked which will cause large heat loss, increase the internal pressure of the valve and reduce the service life of the valve.

1. Design of GOOLE  V-PORT Filter

 With the V-Port Design, impurity particles are cut off at the bottom of the filter and media can pass the V-Port normally which will not increase heat loss, increase the internal pressure of the valve or reduce the service life of the valve.

1. Selectable pressure relief methods and cleaning methods

 The standard pressure relief configuration of this filter valve is the pressure relief valve structure. Meanwhile, it’s able to use the threaded ball valve to replace the pressure relief valve.

1. Design of pressure relief valve

 In the cleaning /Maintenance of the valve, it’s able to relieve the pressure inside the valve by the pressure relief valve and then open the drain outlet to clean / maintain the filter. It has a reliable security performance.

1. Design of threaded ball valve

 It’s able to relieve the pressure inside the filter valve by the threaded ball valve. After opening the threaded ball valve, release the pressure inside the valve until there’s is no pressure. Exert pressure to one side of the threaded ball valve with a pneumatic pump to remove the dust and impurities inside the filter.

Using Method of self-filtering fully welded ball valve

Installation and application methods

 The arrow pointing of the valve is the flow direction of media. Close the ball valve, open the slipknot bolt of the flange cover, take out the filter and then it’s able to remove the blocked impurities.

Cleaning Process

1. Under the normal working condition, the arrow of the self-filtering fully welded ball valve points to the flow direction of media.
2. Close the filter valve, and gradually release the pressure inside the filter ball valve until there’s no pressure.
3. When there’s no pressure inside the valve, slowly open the drain outlet of the filter valve.
4. Slowly get rid of the fluid dirt and impurity particles inside the valve.
5. Take out the filter full of particles and impurities after taking down the bolt to fix the filter.
6. Re-install the cleaned/exchanged filter inside the valve and start the normal operation.
