Structural Features
Tri-Eccentric Structure: A tri-eccentric design is adopted between the valve disc and valve seat, which reduces friction, improves sealing performance, and ensures zero leakage during long-term use.
Stainless Steel Material: The valve body and internal components are made of high-quality stainless steel (e.g., A351 CF8), featuring high strength and good corrosion resistance, which can resist the erosion of various chemical media.
Pneumatic Actuator: Equipped with a high-performance pneumatic actuator, it enables fast and precise remote control and automated operation. The actuator offers multiple options, such as double-acting and single-acting, to meet different control requirements.
Fire-Safe Design: Complies with the API 607 standard. Even in case of fire, the valve can maintain sealing performance to prevent medium leakage and ensure system safety.
Anti-Static Device: Built-in anti-static device effectively prevents static accumulation, reduces the risk of fire and explosion, and is particularly suitable for controlling flammable and explosive media.
Compact Design: Small in size and light in weight, it is easy to install and integrate into existing systems, saving space.
Multiple Operation Modes: Can be equipped with manual, pneumatic, electric, or hydraulic actuators to achieve remote and automated control.
