Why Choose the ET Butterfly Valve?
In the highly competitive realm of industrial valves, the ET butterfly valve stands as a 'hexagonal warrior' par excellence! With its unwavering pursuit of international compatibility, meticulous enhancement of coating technology, and innovative material use, this valve not only shatters installation and adaptation barriers in the industry but also redefines durability and reliability with its formidable strength. Join us as we delve into the 'superpowers' of the ET butterfly valves and discover how they emerge as the 'all-round players' in the industrial arena!
International Compatibility: A Universal 'Valve Language'
The valve's installation top flange aligns perfectly with the IS05211 standard, allowing seamless integration with corresponding actuators.
All ET valves boast extended necks to accommodate a minimum of 2" (50 cm) of pipeline insulation, ensuring optimal performance.
1. Top Flange
The ET butterfly valve's top flange adheres rigorously to the ISO 5211 standard. Whether integrating with high-precision actuators from Europe and the USA or cost-effective domestic drive systems, installation is a breeze, effectively resolving any 'size mismatch' issues and doubling on-site installation efficiency!
2. Extended Valve Neck
For challenging scenarios requiring pipeline insulation, ET unveils its ace - a 2" (50 cm) extended valve neck! Even enveloped in dense insulation, the valve remains nimble, catering perfectly to industries like chemical and energy sectors with stringent insulation demands.
Coating Black Technology: Equipping the Valve with 'All-Round Protective Armor'
1. Valve Body Epoxy Coating
ET products utilize an epoxy coating on the valve body, applied through electrostatic spraying. The epoxy resin powder coats the surface of ordinary ribbed and round steel bars, forming a protective layer over the valve body.
>>> Corrosion Resistance
Epoxy-coated steel bars offer excellent corrosion resistance, with bonding strength much lower than concrete, ideal for industrial settings with humid or corrosive conditions.
>>> Strong Adhesion
The epoxy resin's polar hydroxyl groups and ether bonds ensure high adhesion across substances. Its low shrinkage during curing minimizes internal stress, preventing the protective layer from easily detaching.
>>> Electrical Properties
The cured epoxy resin system excels as an insulating material, boasting high dielectric properties, surface leakage resistance, and robust arc resistance.
>>> Fungus Resistance
Resistant to most fungi, the cured epoxy resin system withstands even the harshest tropical conditions.
2. Valve Plate Nylon Material
Nylon 11's remarkable corrosion resistance finds successful application across diverse fields, including water, mud, food, and seawater desalination.
>>> Outdoor Performance
Fresh's nylon 11 coating withstands a 2000-hour salt dew test and shows no peeling even after 25 years of seawater immersion, protecting metal components from corrosion.
>>> Abrasion Resistance
Boasting superior wear resistance, it handles rigorous industrial demands with ease.
>>> Impact Resistance
Demonstrates exceptional durability, showing no peeling even under intense impact.
3. Valve Plate Sprayed with Teflon/ECTFE
The valve plate treated with a Teflon (ECTFE) coating represents a pinnacle in anti-corrosion and wear-resistant technology. This innovation is pivotal across numerous sectors including the chemical industry, food processing, and more, where durability and performance are non-negotiable.

>>> Electrical properties
With superior insulating properties, ceramics and alumina prevent electrical hazards or equipment damage in specialized electronics and chemical industries, offering unmatched safety when electrical insulation is crucial.
5. Spray tungsten carbide on the valve plate
Tungsten carbide, celebrated for its extreme hardness, when applied to butterfly valve plates, serves as a formidable defense against the abrasive wear from granular substances. Its application in industries like mining and cement dramatically boosts valve longevity, slashes maintenance frequencies, and curtails costs.
>>>Corrosion resistance
In diverse corrosive settings, tungsten carbide excels by forming a robust protective barrier against acidic and alkaline media, safeguarding the valve plate from corrosive damage.
>>>Wear resistance
Boasting unrivaled hardness, tungsten carbide offers extraordinary wear resistance, securing its place as an industry leader.
>>>Good thermal conductivity
With stellar thermal conductivity, tungsten carbide efficiently dissipates operational heat from the valve plate, averting heat-induced degradation or damage. This critical feature extends the valve's lifespan, particularly under high-temperature or high-load conditions, significantly enhancing its reliability.
6. Zero treatment of carbon steel valve body surface
ET ensures the carbon steel valve body is meticulously protected against corrosion, acting as a primer to boost paint adhesion and enhance the corrosion resistance of the paint film. This treatment also reduces wear and enhances lubrication during metal cold processing, optimizing performance and durability.
