Double Eccentric Butterfly Valve with EPDM Seat Material and PN10 Pressure Rating Compliant with Drinking Water Standard

Product Description:

The Double Eccentric Butterfly Valve is a highly efficient and durable valve designed to regulate the flow of water in various industrial and commercial applications. Engineered with precision, this valve features a flange connection that ensures secure and reliable installation within piping systems. The use of flange connections not only provides ease of maintenance but also guarantees a tight seal, minimizing the risk of leaks and enhancing overall system integrity.

One of the standout features of this Double Eccentric Butterfly Valve is its seat material, which is made from high-quality EPDM (Ethylene Propylene Diene Monomer). EPDM is well-known for its excellent resistance to heat, ozone, and weathering, making it an ideal choice for water applications. This seat material ensures a tight seal against the valve disc, preventing any unwanted leakage and contributing to the valve’s longevity and reliable performance.

The valve is designed to operate efficiently across a temperature range of -10 to 80 degrees Celsius. This temperature range makes it suitable for a wide variety of water system applications, including potable water, wastewater treatment, and industrial water processes. The ability to function effectively within this temperature span ensures that the valve maintains its sealing performance and structural integrity under varying thermal conditions.

In terms of pressure handling capabilities, the Double Eccentric Butterfly Valve is rated for PN10, PN16, and PN25 pressures. This flexibility allows the valve to be used in different pressure environments, providing robust performance even under higher pressure conditions. The valve's design incorporates a double eccentric mechanism, which significantly reduces friction between the disc and seat during operation. This design feature not only extends the service life of the valve but also ensures smooth and reliable operation with minimal wear.

Another important characteristic of this valve is its compliance with recognized standards such as BS (British Standard) or ANSI (American National Standards Institute). Adherence to these standards guarantees that the valve meets rigorous quality, safety, and performance criteria, making it a dependable choice for engineers and system designers worldwide. The availability of valves manufactured according to these standards ensures compatibility with existing systems and regulatory requirements.

The Double Eccentric Butterfly Valve is designed with a bare head, which simplifies the installation and maintenance processes. The bare head design allows for easy access to the valve’s internal components without the need for extensive disassembly. This feature is particularly beneficial in applications where quick inspection and servicing are critical to maintaining uninterrupted system operation.

One of the notable operational advantages of this valve is its big torque capability. The double eccentric design reduces the torque required to open or close the valve, enabling smoother operation even in high-pressure conditions. This big torque feature translates into lower actuator power requirements and enhanced energy efficiency, making the valve an economical and environmentally friendly solution for water control systems.

Primarily used in water-related applications, this valve excels in controlling the flow and isolation of water in pipelines. It is widely employed in water treatment plants, irrigation systems, municipal water supply networks, and industrial water processing facilities. Its robust construction, reliable sealing, and ease of operation make it a preferred choice for operators seeking long-term performance and minimal maintenance.

In summary, the Double Eccentric Butterfly Valve with flange connection, EPDM seat material, and a temperature range of -10 to 80℃ is an excellent solution for water applications requiring reliable flow control under varying pressure conditions (PN10, PN16, PN25). Its bare head design facilitates easy maintenance, while compliance with BS or ANSI standards assures quality and compatibility. The big torque operation feature ensures smooth valve actuation, making this valve an indispensable component in modern water management systems.
