Core Structure & Sealing Performance
Featuring a triple eccentric design, this valve is equipped with a metal and graphite laminated disc seal, with an optional solid metal disc available. This combination delivers the dual advantages of metal hard sealing and graphite soft sealing: the sealing face is wear-resistant and corrosion-resistant, maintaining excellent sealing performance even under high-temperature conditions, while meeting strict low emission requirements in line with environmental and industrial safety standards.
Operational & Safety Features
Low operating torque: The triple eccentric design significantly reduces opening/closing friction, enabling effortless operation and compatibility with low-power actuators.
Anti-blowout stem: The stem is engineered with an anti-blowout structure to prevent ejection under media pressure, enhancing operational safety.
Fire-safe test design (optional): Optional fire-safe certified design ensures reliable sealing during fire incidents, safeguarding pipeline integrity.
Bi-directional (reverse pressure relief): Supports bi-directional fluid flow and enables pressure relief in reverse operation, adapting to complex pipeline layouts.
Installation & Longevity Advantages
ISO5211 top flange: Standardized top flange design allows direct mounting to a wide range of pneumatic/electric actuators, ensuring easy installation and high compatibility.
Long service life: The sealing face and disc are made of wear-resistant and fatigue-resistant materials, maintaining stable performance after frequent cycles and greatly extending maintenance intervals and service life.
Application Scenarios
Suitable for high-temperature, high-pressure, and flammable/explosive industries such as petrochemical, power generation, and metallurgy, especially for industrial pipelines demanding strict sealing, safety, and durability.
