The 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 disc ensures high corrosion resistance, excellent surface hardness, and long-term reliability in harsh service environments.
In terms of application, the EPDM soft replaceable seat split stem lug butterfly valve is ideal for use in HVAC systems, water and wastewater treatment plants, fire protection systems, marine applications, and a variety of industrial processes where flow control, reliability, and ease of maintenance are critical.
