Double Eccentric Butterfly Valve with Stainless Steel Disc and EPDM Seal for Water Applications with FM Certificate

Product Description:

The Double Eccentric Butterfly Valve is a highly reliable and efficient valve designed specifically for water applications. Engineered with precision, this valve stands out due to its robust construction and superior performance, making it an ideal choice for various water systems ranging in size from 1 inch to 72 inches. Its innovative double eccentric design significantly reduces seat friction, ensuring smoother operation and longer service life compared to traditional butterfly valves.

One of the key features of this valve is its disc material, which is made from high-quality stainless steel. The use of stainless steel for the disc ensures excellent corrosion resistance, durability, and strength, enabling the valve to withstand harsh water environments and maintain optimal performance over extended periods. This makes the valve particularly suitable for potable water and other clean water applications, where maintaining water purity and valve integrity is crucial.

The valve is designed to comply with drinking water standards, ensuring that it meets all necessary regulations for safe use in potable water systems. This compliance guarantees that the materials and seals used within the valve do not contaminate the water, making it a trusted choice for municipal water distribution, water treatment plants, and other critical infrastructure projects.

Featuring an EPDM seal, the Double Eccentric Butterfly Valve offers excellent sealing performance and chemical resistance. EPDM (Ethylene Propylene Diene Monomer) seals are known for their superior elasticity and resistance to a wide range of chemicals and temperature variations, which helps maintain a leak-proof seal even under varying pressure conditions. This contributes to the valve’s reliability and reduces maintenance requirements, further enhancing its appeal for water applications.

The valve is available with different pressure ratings including PN10, PN16, and PN25, accommodating a broad spectrum of water pressure conditions. This flexibility allows users to select the appropriate valve specification based on their system requirements, ensuring optimal performance and safety. Whether the application involves low-pressure residential water systems or higher-pressure industrial water pipelines, this valve can be tailored to meet those demands.

Additionally, the Double Eccentric Butterfly Valve can be equipped with a valve worm gear mechanism. The valve worm gear available option provides easier and more precise valve operation, especially for larger valve sizes or installations where manual control requires additional torque. This feature enhances the operability of the valve, allowing for smooth and controlled opening and closing actions, which is crucial in maintaining system stability and preventing water hammer effects.

In summary, the Double Eccentric Butterfly Valve is a versatile, durable, and highly efficient valve solution for water applications. Its stainless steel disc, EPDM sealing, compliance with drinking water standards, and availability in multiple sizes and pressure ratings make it suitable for a wide range of water systems. The option to include a valve worm gear further adds to its ease of use and operational control. This valve represents a perfect combination of quality, reliability, and performance for any water-related project, ensuring safe and efficient flow control in both commercial and industrial settings.
