Hard seal butterfly valve features and use environment, as well as procurement precautions, and maintenance of the detailed introduction

Hard seal butterfly valve is a kind of hard material as sealing gasket butterfly valve, has the following characteristics:

1. Good sealing performance: hard material gasket has good wear resistance, high temperature resistance, acid and alkali resistance, to ensure that in high temperature, high pressure, corrosion and other harsh environment effectively prevent leakage.

2. Strong durability: The sealing structure of the hard seal butterfly valve is made of hard material, which is not easy to aging, deformation and damage, and the service life is relatively long.

3. Easy to operate: hard seal butterfly valve adopts lightweight design, light switch, easy to use.

4. Simple installation and maintenance: The hard seal butterfly valve is simple and compact, easy to install and maintain.

Hard sealed butterfly valve is suitable for fluid control under high temperature, high pressure, corrosion and other harsh environment, common use environment including chemical, pharmaceutical, metallurgy, electric power and other industries.

Purchasing matters needing attention:

1. Confirm the use environment: before purchasing, it is necessary to fully understand the use environment and process requirements, and select appropriate materials and specifications.

2. Confirm the pressure level and connection mode: Determine the pressure level and connection mode of the butterfly valve to ensure that it matches the pipeline.

3. Choose reliable brands and manufacturers: choose manufacturers and products with certain popularity and credibility to ensure product quality and after-sales service.

Maintenance:

1. Regular inspection and cleaning: Check the operation of butterfly valve regularly, clean dust and dirt, and prevent valve stuck.

2. Replace the sealing gasket: If the sealing gasket is damaged or aging, replace it in time to prevent leakage.

3. Frequent lubrication: the action part of the butterfly valve needs to be coated with lubricating oil to reduce wear and prolong the service life.

4. Avoid overload: Avoid valve overload, so as not to affect the service life of the butterfly valve.
