Product description
A cast steel trunked ball valve is a type of ball valve used for shutting off, distributing, or regulating the flow of oil, gas, or chemical media.
Features
Low Temperature Adaptability
The Cast Steel Trunnion Ball Valve is made of A352 LCB/LCC low-temperature cast steel, with a stable metallographic structure and impact toughness ≥27J (-196°C), ensuring reliable sealing and stable operation of LNG and cryogenic pipelines.
Balanced Operating Torque
The double-support ball design ensures a ball-support surface contact area ≥80%, resulting in uniform torque distribution. Opening and closing torque is reduced compared to floating ball valves of the same diameter, preventing jamming.
Self-Cleaning Design
The ball surface radius ≥3mm, combined with a hardened seat coating, reduces solid particle accumulation, with a solid impurity blockage rate ≤1%, maintaining smooth opening and closing over the long term.
Low Pressure Drop and Low Flow Resistance
The full-bore design, with the ball orifice diameter equal to the valve body diameter, results in a pressure drop of <5% at the Reynolds number, making it suitable for high-flow, high-pressure systems.
