Triple Offset No-friction Sealing Structure Unique triple eccentric design makes the butterfly plate separate from the sealing surface instantly when opening and closing, no friction wear during frequent switching, effectively avoiding medium leakage caused by seal abrasion, greatly extending service life, suitable for media containing dust and solid particles.
Multi-layer Metal Hard Seal, High Temperature & High Pressure Resistant Adopts stainless steel multi-layer metal wound sealing ring, the maximum working temperature can reach 425℃, applicable for high-temperature steam, flue gas, heat conduction oil; sealing performance up to Class VI bubble tight zero leakage, stable under PN16/PN25 high pressure.
High-strength WCB Cast Steel Flange Body Integral casting carbon steel valve body with anti-rust high-temperature paint, flange bolt fixed installation, strong anti-vibration and anti-thermal deformation ability, stable operation in outdoor and harsh industrial environments.
Extended Heat-insulating Stem Design The lengthened bracket isolates high-temperature heat conduction from the pipeline, effectively prevents the high temperature from damaging the internal sealing parts of the pneumatic actuator, ensures long-term stable operation of the valve under high-temperature working conditions.
Reliable Rack & Pinion Pneumatic Actuator Aluminum alloy anti-corrosion cylinder, optional double acting / spring return fail-safe type for emergency pipeline cut-off; equipped with mechanical position indicator and stroke fine-tuning bolts to ensure accurate switch position.
ISO5211 Standard High Mounting Platform Universal top flange structure, can be directly installed with solenoid valve, limit switch and valve positioner, seamlessly connected to PLC control system to realize remote switch and flow proportional regulation.
