Product features
1. Nickel-based alloy sealing system
Super-hard and wear-resistant combination
Ni60 sphere: Hardness HRC 58-62, resistant to particle wear
Ni55 valve seat: Hardness HRC 55-58, with excellent impact resistance
Excellent corrosion resistance: It has better resistance to acid and alkali corrosion than stainless steel
High-temperature stability: Maintains stable mechanical properties at a high temperature of 550℃
2. V-shaped sphere adjustment characteristics
Precise flow control: The V-shaped cut and the valve seat form a precise flow control window
High regulation ratio: up to 100:1, meeting the requirements of wide-range flow regulation
Shearing function: The V-shaped edge can effectively shear fibrous media
3. Rapid pneumatic actuator system
High-speed response: The specially designed linear stroke cylinder enables rapid action within 0.5 to 2 seconds
Double-acting/single-acting: Spring return fault safety type is available as an option
Precise positioning: An optional positioner is available to achieve precise opening control
4. Specialized structural design
Anti-jamming design: The gap between the ball and the valve seat is optimized to prevent high-temperature jamming
Fire safety: Complies with API 607 standard. A metal seal is formed after the soft seal fails
Anti-blowout valve stem: T-shaped structure valve stem to ensure safety and reliability under pressure
Core parameters
Pressure rating: Class 150-600 (PN16-100)
