Why Choose the ET Butterfly Valve
ET butterfly valves are the epitome of versatility in industrial settings, earning their title as a 'hexagonal warrior.' With an unwavering dedication to global compatibility, advanced coating technology, and innovative material use, they not only overcome installation and adaptation barriers but also redefine valve durability and reliability with exceptional strength. Let's explore the unique 'superpowers' of ET butterfly valves that set them apart as 'all-round players' in the industrial sector!
International Compatibility: A Universal 'Valve Language'
The valve installation top flange is designed to meet the ISO 5211 standard, ensuring seamless installation with compatible actuators.
Every valve features an extended neck to accommodate at least 2" (50cm) of pipeline insulation.
1. Top Flange
ET butterfly valve's top flange conforms rigorously to the ISO 5211 standard, enabling seamless integration with both precision actuators from Europe and America and cost-effective domestic drive devices. Say farewell to installation headaches caused by 'size mismatch' and enjoy a doubled on-site installation efficiency!
2. Extended Valve Neck
In scenarios requiring complex pipeline insulation, ET presents the 'king bomb' of solutions: a valve neck extended to at least 2" (50cm)! Even with thick insulation layers, the valve operates smoothly, perfectly suited for industries like chemicals and energy with stringent insulation needs.
Coating Black Technology: The Valve's 'All-Round Protective Clothing'
1. Valve Body Epoxy Coating
ET's valve bodies use an epoxy coating, applied through an electrostatic spraying process. This technique coats ordinary ribbed and round steel bars with an epoxy resin layer, fortifying the valve body surface.
>>> Corrosion Resistance
The epoxy resin-coated steel bars boast excellent corrosion resistance, with bonding strength significantly surpassing that of concrete, making them ideal for industrial environments with moisture or corrosive media.
>>> Strong Adhesion
The epoxy resin's molecular chain, featuring polar hydroxyl groups and ether bonds, ensures high adhesion to diverse materials. Its low shrinkage during curing minimizes internal stress, preventing the protective coating from detaching and failing.
>>> Electrical Properties
The cured epoxy resin system delivers superior insulation with high dielectric strength, resistance to surface leakage, and excellent arc resistance.
>>> Fungus Resistance
Resilient against most fungi, the cured epoxy resin system performs well even in harsh tropical climates.
2. Valve Plate Nylon Material
Nylon 11 exhibits outstanding corrosion resistance and is effectively utilized in various fields, including water, mud, food, and seawater desalination applications.
>>> Outdoor Performance
Nylon 11 coating by Fresh has excelled in the 2000-hour salt dew test and has remained intact after 25 years of seawater immersion, thus preventing corrosion of metal parts.
>>> Abrasion Resistance
It provides exceptional wear resistance.
>>> Impact Resistance
Shows no signs of peeling even under significant impact.
3. Valve Plate Sprayed with Teflon/ECTFE
Our valve plate, expertly sprayed with Teflon (ECTFE), boasts an advanced anti-corrosion and wear-resistant technology. This revolutionary coating is perfect for industries like chemical processing and food production, where durability is key.
>>>Corrosion resistance
Engineered to withstand aggressive chemical erosion from substances such as strong acids, alkalis, and organic solvents, the valve ensures long-lasting stability under demanding conditions.
>>>Low friction
Designed to minimize friction loss, this valve boosts operational efficiency and prolongs equipment life.
>>>Easy to clean
Its non-stick surface simplifies cleaning, significantly cutting down maintenance costs over time.
>>>High temperature resistance
Capable of withstanding high temperatures, the valve maintains mechanical integrity and reliability in extreme conditions.
4. Valve plate sprayed with ceramic/alumina
Crafted with alumina ceramics, known for their outstanding hardness, this ET butterfly valve plate excels in resisting violent erosion from high-speed fluids containing abrasive particles, maintaining durability against mechanical wear.
>>> Corrosion resistance
The ceramic coating resists harsh chemical erosion, ensuring long-term stability even in environments with aggressive acids, alkalis, and solvents.
>>> Wear resistance
Exhibiting exceptional wear resistance, it is built to withstand the toughest industrial challenges.
>>> High temperature resistance
Tailored for high-temperature environments, it preserves the stability of essential mechanical parts.
>>> Electrical properties
As excellent insulators, ceramics and alumina offer superior electrical insulation, preventing potential safety hazards or equipment damage due to electrical conductivity, particularly in electronics and chemical industry applications.
5. Spray tungsten carbide on the valve plate
Renowned for its unparalleled hardness, tungsten carbide, when applied to the butterfly valve plate, shields against wear from granular materials. In sectors like mining and cement, this coating not only prolongs valve life but also minimizes maintenance costs.
>>>Corrosion resistance
Tungsten carbide offers formidable resistance in corrosive settings, forming a protective barrier that guards against acid and alkali damage.
>>>Wear resistance
With exceptional hardness, it provides superior wear resistance, ensuring longevity.
>>>Good thermal conductivity
Boasting excellent thermal conductivity, tungsten carbide dissipates heat efficiently, preventing damage due to heat build-up. This enhances the valve's lifespan and reliability, especially in high-temperature or high-load scenarios.
6. Zero treatment of carbon steel valve body surface
Our advanced treatments shield the valve body metal, providing essential protection against corrosion. As an ideal primer before painting, it enhances paint adhesion and corrosion resistance. Additionally, it reduces wear and serves as a lubricant in metal cold processing techniques.
