EPDM Soft Seal WCB Body 5A Disc Lug Butterfly Valve
Basic Info of 5A Disc Lug Butterfly Valve
- The EPDM Soft Replaceable Seat Lug Butterfly Valve is a flow control device designed for reliable sealing and ease of maintenance. EPDM rubber seat ensures excellent resistance to water, steam, and a wide range of chemicals, making it ideal for HVAC, water treatment, and general industrial applications.
- The 5A lug-style butterfly valve body allows for end-of-line service and easy installation between flanges.
- The replaceable seat design extends the valve’s service life by enabling quick seat replacement without removing the valve from the pipeline.
- This combination of durability, efficiency, and serviceability makes it a preferred choice for demanding flow control systems.
- Unlike traditional one-piece stem configurations, the split stem enhances mechanical strength and torque transmission, making it ideal for high-pressure systems and frequent cycling.
- The dual stem setup also improves alignment and reduces wear on internal components, extending the life of the valve.
- The valve body is made of WCB, a rugged material with excellent mechanical strength and resistance to shock, pressure, and thermal stresses. WCB is widely used in industrial valve manufacturing due to its performance in high-pressure and high-temperature environments. This makes the valve suitable for more demanding applications compared to valves with cast iron or ductile iron bodies.
- The 5A-grade disc is a duplex stainless steel. The 5A lug butterfly valve ensures high corrosion resistance, excellent surface hardness, and long-term reliability in harsh service environments.
