It can be customized according to different needs.

I. Product features (can be customized according to different needs)

1. Double eccentric structure: automatically compensate for the wear of sealing surface to ensure long-term reliable sealing performance.
2. Electric actuator: easy to operate, fast response speed, suitable for frequent opening and closing conditions.
3. Reliable sealing performance: the sealing ring can be replaced, easy maintenance, no need to disassemble the entire valve to replace the sealing ring, reduce maintenance costs.
4. Compact structure: especially suitable for installation environment with limited space.
5. Wide range of application: temperature range of -10 ℃ to 80 ℃, applicable to a variety of working conditions.
6. Strong durability: extend the service life of the valve, reduce maintenance frequency.

II. The use of the scene
Municipal water supply and drainage system, industrial piping system, water treatment system, energy system, marine system.

III. Applicable media
Can be applied to a variety of media, including but not limited to:
Liquid: water, seawater, salt water, acid and alkali solutions.
Gas: air, natural gas, coal gas.
Other media: food, drugs, oils

IV. Temperature range: -10℃ to 80℃.

V. Material

Valve body material

Ductile cast iron (GGG45): with good strength and toughness, suitable for low and medium pressure working conditions.
Carbon steel (such as WCB): suitable for higher pressure and temperature conditions.

Valve plate material
Ductile cast iron: consistent with the valve body material to ensure overall strength.
Stainless steel: suitable for working conditions requiring higher corrosion resistance.

Valve shaft material
Stainless steel: strong corrosion resistance, high strength, suitable for use with the valve body and butterfly plate materials.

Seal ring material:Valve body body material

Packing material
Flexible graphite: has good sealing and high temperature resistance, to ensure the reliability of the valve sealing in high temperature conditions.
