Lift Plug Valve: Reliable Sealing for Harsh Industrial Environments

ZZJG VALVE produce lifting-type plug valves. These valves are used in industrial pipelines that require reliable shut-off and long-term operation. The lifting-type plug valve features a lifting and rotating structure. When the Lifting Plug Valve is opened, the valve core moves upward first. After the valve core leaves the valve seat, it rotates. When the Industrial Lifting Plug Valve is closed, the valve core rotates to the closed position first. Then the plug valve core moves downward and presses against the valve seat.

This structure can reduce the friction between the valve core and the valve seat. It can also reduce the wear on the sealing surfaces. After multiple openings and closings of the valve, the sealing surfaces can still maintain a good condition. This can extend the service life of the plug valve.

The Lifting and Rotating Structure Reduces Wear

One of the main features of the lifting-type plug valve is that the valve core rises first, then rotates. In ordinary plug valves, when opening and closing, the valve core may directly contact the sealing surface. Valves often opening and closing can cause the sealing surface to wear. When there are solid particles in the pipeline, the wear of the sealing surface will be more obvious.

The lifting-type plug valve can reduce this contact. When the valve is opened, the valve core moves upward first. Then it rotates after leaving the valve seat. When the valve is closed, the valve core rotates to the closed position first. Then the valve core moves downward and contacts the valve seat. This structure can reduce the friction between the sealing surfaces. It can also reduce the wear of the valve core and the valve seat. This lift plug valve can maintain a good sealing effect. It is also suitable for industrial pipelines that need to be opened and closed multiple times.

Reliable Sealing in Industrial Pipelines

The lifting-type plug valve can use soft seals or metal seals. Soft seals are suitable for ordinary industrial pipelines. Soft seal materials can provide better sealing effects. Metal seals are suitable for high-temperature and high-pressure pipelines. Metal seals are also suitable for pipelines with complex working conditions.

Users can choose the sealing method based on the working conditions of the pipeline. The lifting-type plug valve can use different materials. The valve body, valve core, valve stem, and seals can use different materials. Common materials include carbon steel, stainless steel, and alloy steel. The material needs to be selected based on the pipeline medium. The material also needs to be selected based on pressure and temperature. The appropriate material can allow the valve to last longer.

Suitable for High Pressure and High Temperature Conditions

Many industrial pipelines operate under high pressure and high temperature conditions. Some pipelines also transport dust, solid particles, and other impurities.

The lifting-type plug valve can reduce the direct contact between the valve core and the sealing surface. When the valve is opened, the valve core moves upward first. Then it rotates. When the valve is closed, the valve core rotates first. Then the valve core moves downward. This process can reduce the friction between the sealing surfaces. It can also reduce the damage to the sealing surfaces.

The lifting-type plug valve can be used in the petroleum, natural gas, chemical, petrochemical, power, metallurgy, and coal chemical industries. These industries' pipelines usually require better sealing performance. Some pipelines also need the valve to withstand high temperatures and high pressures.

The lifting-type plug valve can use a straight flow channel. The straight flow channel can reduce the resistance when the medium passes through the valve. It can also reduce pressure loss. The pipeline can maintain a good flow.

Application in Petroleum and Chemical Systems

The lifting-type plug valve can be used for the cutting and isolation of industrial pipelines.

- In the petroleum and natural gas industry, the lifting-type plug valve can be used in oil and gas pipelines, refining equipment, and high-pressure pipelines. The valve can cut off the medium in the pipeline.

- In the petrochemical and chemical industries, the lifting-type plug valve can be used in high-temperature and high-pressure medium pipelines. Users can choose the appropriate valve body material and sealing material.

- In the power industry, the lift type plug valve can be used for pipelines that require reliable shut-off. The valve can be installed at the inlet and outlet of equipment and process pipelines.

- In the metallurgy, mining and coal chemical industries, some pipelines transport dust, solid particles and other impurities. These media are prone to wear the valve. The lift type plug valve can reduce the contact between the valve core and the sealing surface. It can reduce friction and wear.

ZZJG VALVE Lift Type Plug Valve

ZZJG VALVE can be produced according to customer requirements as lift type plug valves. Customers can provide information such as pipeline dimensions, pressure ratings, working temperatures, media and materials.

This valve can use different valve body materials. The valve can also use different sealing materials. Users can choose the appropriate product according to actual working conditions.

ZZJG VALVE can provide different operating methods. Users can choose manual operation, gear operation or pneumatic operation.

The lift type plug valve operates in a way of first lifting and then rotating. When the valve is opened, the valve core leaves the sealing surface first. The valve core then rotates. When the valve is closed, the valve core first rotates to the closed position. The valve core then moves downward and presses the sealing surface tightly.

This structure can reduce the friction between the valve core and the sealing surface. It can reduce the wear of the sealing surface. The valve can also maintain a good sealing effect.

The lift type plug valve of ZZJG is used in industrial pipelines that require shut-off and isolation of media. This valve can be used in the petroleum, natural gas, chemical, power and other industrial fields.
