The thinnest butterfly valve, which can save space.
The material is ductile iron GGG50, the most commonly used as it has high tensile strength.
Not easy to deform and shift.
It offers good corrosion resistance, high strength, and hardness.
With chemical resistance, it can resist various chemicals. The disc uses EPDM rubber to completely cover the internal surface, thereby providing excellent chemical corrosion resistance.
ISO 5208, API598, EN1266-1.
Butterfly Valve Is Used For Water system, waste water system, and gas pipelines with temperatures ≤120°C and nominal pressures ≤16MPa in food, medicine, chemical industry, petroleum, electric power, urban construction, textile, papermaking, etc.

A worm gear operated CF8 disc double stem wafer butterfly valve is a type of industrial valve that is used to control the flow of a fluid through a pipeline. It is operated by a worm gear mechanism and features a CF8 disc with double stems for added strength and stability.
Some key features include a compact wafer design for easy installation, a durable CF8 disc for reliable performance, a double stem design for added strength, and a worm gear mechanism for precise operation and control. Benefits include its compact and lightweight design, ease of installation, reliability, cost-effectiveness, and minimal required maintenance.
This type of butterfly valve is commonly used in various industries including chemical, petrochemical, oil and gas, water and wastewater, power generation, and HVAC. It is suitable for both general and industrial applications.
Main materials include stainless steel for the body and disc, and carbon steel for the stem and internal components for optimal durability and corrosion resistance. Transportation is by sea, by air mainly, and we also accept express delivery.
