API 600, BS 6364 Cryogenic Gate Valve (Low Temperature Valve)
Specification:
1. Design standard: API 600, BS 6364
2. Body material: Stainless Steel, Alloy Steel
3. Nominal diameter: NPS 2-36 Inch
4. Pressure range: Class 150-600 LB
5. End connection: RF, RTJ, BW
6. Minimum working temperature: -196 ℃
7. Mode of operation: Hand wheel, Gear box, Electric, Pneumatic, hydraulic device, Pneumatic-hydraulic device
Features:
1. Spring loaded packing can be chosen
2. Valve has medium flow direction requirements.
3. Low emission packing can be chosen according to ISO 15848 requirement.
4. Small flow resistance for fluid, only a small force is required when opening or closing.
5. When valve is full opened, the sealing surface suffered small friction from the working medium.
6. With pressure relief hole to prevent abnormal pressure rise in cavity
Main features: Low temperature valve is designed with extended bonnet, which can protect stem packing and stuffing box area to avoid the effect from low temperature that causing the stem packing lost its elasticity. Extended area is also convenient for insulation protection. Valves are suitable for Ethylene, LNG plants, air separation plant, Petrochemical gas separation plant, PSA oxygen plant, etc.
