This resilient seated butterfly valve features a double flange design, making it suitable for dead-end service. The valve series boasts several design advantages, including high Cv ratings, minimal exposure of parts to the line media, greater reliability, and a proven long service life. A key benefit of this valve is its international compatibility, as the same valve can be used with various global flange standards, such as ASME Class 125/150, BS 10 Tables D and E, BS 4504 PN 10/16, DIN PN 10/16, AS 2129, and JIS 10. Additionally, the valves are designed to meet ISO 5752-Table 2 (EN 558 Table 13) face-to-face dimensions and ISO 5211 actuator mounting flange standards.
Double flanged Butterfly Valves constitute an indispensable element in numerous industrial and commercial systems, meticulously crafted to modulate the fluid flow within pipes. These highly versatile valves are gaining escalating popularity owing to their well-balanced combination of durability, reliability, and cost-efficiency when juxtaposed with more conventional ball valves.
Multiple applications: These valves are applicable across a broad spectrum of scenarios, rendering them a preferred choice for industries like water treatment, oil and gas, and chemical processing.
Actuator Options: These valves can be outfitted with either pneumatic or electric actuators, offering flexibility to satisfy a diverse range of operational requirements. The selection of the actuator influences the control mode of the valve - pneumatic actuators for swifter operation and electric actuators for more precise control.
Accessory compatibility: To augment functionality, double-flanged butterfly valves can be furnished with a multiplicity of accessories. Options encompass switch boxes for operational feedback, solenoids for automatic control, air filter regulators for pressure maintenance, and 4-20mA electro-pneumatic positioners for fine-tuning the valve position.
Quality Assurance: Every valve is comprehensively assembled and stringently tested to guarantee optimal performance and dependability, providing you with a sense of reassurance in critical operations.
APPLICATIONS
Double flanged butterfly valves are robust and adaptable and are extensively employed in a variety of applications. They are ideally tailored for:
Water and wastewater management: proficiently regulating the flow in municipal and industrial water supply systems.
Petrochemical processes: governing the transportation and processing of hydrocarbons and other chemicals.
HVAC systems: Regulating the air and fluid flow in heating, ventilation, and air conditioning systems to enhance energy efficiency.
Mining operations: handling abrasive materials and controlling slurries during the extraction process.
