Structure & Working Principle
Design Features:
Lift-type design: Ingeniously crafted, the disc moves precisely along the vertical centerline of the valve body, perfectly tailored for vertical installation.
Spring-assisted sealing: This advanced feature ensures an immediate and efficient response to any pressure fluctuations, with select models boasting reinforced springs for seamless performance in horizontal pipeline settings.
Operation:
Closed by default: Engineered to perfection, the valve remains securely shut under no-flow conditions, ensuring reliability.
Forward flow: The robust inlet pressure triumphs over spring force, elevating the disc to facilitate a smooth, unhindered flow.
Reverse flow prevention: A sophisticated combination of spring and backpressure firmly forces the disc closed, effectively blocking any potential backflow.
Key Specifications
Pressure Rating: Ranges from PN16 to PN40, equivalent to 150LB to 300LB, catering to diverse industrial requirements.
Temperature Range:
- Carbon steel (WCB): Handles temperatures up to 425°C, perfect for water, oil, and steam applications.
- Stainless steel (304/316): Supports up to 200°C, ideal for corrosive media environments.
Materials & Standards
- Body Materials:
- Choose between robust carbon steel (WCB) or premium stainless steel (304/316) for optimal performance.
Dimensions & Connection
-Nominal Diameter (DN): Available in a comprehensive range from DN15 to DN350.
-Connection Type: Designed with versatile flange options including RF/FF for seamless integration.
Applications
- Media: Versatile capability for water, steam, oils, as well as handling weak acids like nitric acid and strong corrosives such as acetic acid.
- Industries:
- Oil & gas: Maintains unidirectional flow control with precision.
- Pharmaceutical: Expertly prevents backflow contamination, safeguarding product purity.
- Power plants: Essential for boiler feedwater protection, ensuring operational safety.
- Wastewater treatment: Integral for pump discharge lines, enhancing system efficiency.
Installation & Maintenance
