4. Nominal diameter: NPS 1/2-24 Inch
5. End connection: RF, RTJ, BW
6. Minimum working temperature: -196 ℃
7. Mode of operation: Lever, Gearbox, Electric, Pneumatic, hydraulic device, Pneumatic-hydraulic device
8. Main features: Low-temperature ball valve is designed with an extended bonnet, which can protect the stem packing and stuffing box area to avoid the effect of the low temperature that causes the stem packing to lose its elasticity. An extended area is also convenient for insulation protection. Valves are suitable for Ethylene, LNG plants, air separation plant, Petrochemical gas separation plant, PSA oxygen plants, etc.
Product features
1. Flow resistance is small, fire safe, antistatic design
2. Floating type and trunnion mounted type can be chosen according to the requirement
3. Soft seat design with good sealing performance
4. When the valve is in a fully open position, seat surfaces are outside the flow stream that is always in full contact with the gate that can protect seat surfaces
