Driven by an unwavering commitment to international compatibility, advanced coating technologies, and innovative material usage, this valve not only shatters industry installation and adaptation barriers but also redefines durability and reliability with its robust performance. Join us as we delve into the "superpowers" of ET butterfly valves and explore their transformation into an "all-round player" in the industrial sector!
International Compatibility: A Universal "Valve Language"
Our valve's installation top flange is meticulously engineered to meet the IS05211 standard, enabling seamless and direct installation with compatible actuators.
Every valve features extended necks, catering to the needs of at least 2" (50cm) pipeline insulation requirements.
1. Top Flange
ET butterfly valve's top flange adheres strictly to the ISO 5211 standard. Whether you're using a precision actuator from Europe or the USA, or a high-value domestic drive device, it facilitates effortless integration, eliminating installation headaches caused by "size mismatch," and effectively doubles the efficiency of on-site installations!
2. Extended Valve Neck
When faced with complex scenarios needing pipeline insulation, ET triumphantly presents the "king bomb" - a minimum of 2" (50cm) extended valve neck! Even if encased in a thick insulation layer, the valve operates smoothly, perfectly adapting to industries such as chemicals and energy, where insulation demands are exceptionally high!
Revolutionary Coating Technology: Equipping the Valve with "All-round Protective Armor"
1. Epoxy Coating for Valve Body
ET's valve body is treated with an epoxy coating applied via electrostatic spraying. Epoxy resin powder is meticulously sprayed onto ordinary ribbed and round steel bars, creating a robust coated surface on the valve body.
>>>Corrosion Resistance
Epoxy resin-coated steel bars exhibit exceptional corrosion resistance and significantly lower bonding strength compared to concrete, making them ideal for industrial settings with humid or corrosive media.
>>>Strong Adhesion
The epoxy resin's molecular chain, with its polar hydroxyl groups and ether bonds, ensures strong adhesion to various substances. With minimal shrinkage during curing and reduced internal stress, the protective surface coating remains intact and reliable.
>>>Electrical Properties
