Structure & Working Principle
Design Features:
Ingenious Lift-type Design: The disc elegantly moves along the valve's vertical axis, making it perfect for vertical setups.
Innovative Spring-assisted Sealing: Designed for quick adaptability to pressure changes. Select models boast enhanced springs for horizontal use.
Operation:
Engineered Closed by Default: Ensures the valve remains secure in the absence of flow, enhancing system reliability.
Forward Flow Dynamics: The inlet pressure triumphs over spring resistance, granting smooth, uninterrupted flow.
Reverse Flow Protection: The interplay of spring tension and backpressure reliably seals the disc, thwarting backflow.
Key Specifications
Pressure Rating: Ranging from PN16 to PN40 (150LB-300LB), adaptable for various system needs.
Temperature Range:
- Carbon steel (WCB): Efficient up to 425°C for water, oil, and steam.
- Stainless steel (304/316): Optimal performance up to 200°C in corrosive environments.
Materials & Standards
- Body Materials:
- Select from Carbon steel (WCB) or the reliable Stainless steel (304/316) for diverse applications.
Dimensions & Connection
-Nominal Diameter (DN): From DN15 to DN350, catering to a broad spectrum of requirements.
-Connection Type: Flange (RF/FF) for secure and flexible installations.
Applications
- Media: Handles water, steam, oils, mild acids like nitric acid, and strong corrosives such as acetic acid.
- Industries:
- Oil & Gas: Ensures precise unidirectional flow control for safety and efficiency.
- Pharmaceutical: A vital component in preventing backflow contamination, safeguarding product integrity.
- Power Plants: Essential for protecting boiler feedwater, maintaining system integrity.
- Wastewater Treatment: Optimizes pump discharge lines, enhancing operational efficiency.
Installation & Maintenance
- Installation: Vertical mounting ensures gravity-augmented sealing; pipeline cleanliness is paramount.
- Maintenance:
- Regular inspections of springs and sealing surfaces are recommended for sustained performance.
- Vigilantly monitor for thermal fatigue in high-temperature applications to ensure longevity.
