Cast Iron Butterfly Valve Trigger Lever

Cast Iron Butterfly Valve Trigger Lever

Application

The VT Cast Iron Butterfly Valve Trigger Lever is a versatile and reliable component used in various industrial applications. The valve is constructed with a sturdy cast iron body, providing exceptional strength and durability, making it ideal for handling demanding conditions and high-pressure systems.

The key feature of Cast Iron Butterfly Valve Trigger Lever is the lever mechanism itself, which provides ease of operation and precise control. The trigger lever allows for quick and effortless opening and closing of the valve, making it suitable for applications where frequent adjustments are required. The lever can be easily engaged or disengaged, enabling swift response times and minimizing downtime.

With a butterfly disc that rotates on a central axis, this valve offers excellent flow control capabilities. The disc’s low-profile design minimizes pressure drop and turbulence, ensuring smooth and efficient fluid flow. Additionally, the cast iron construction provides resistance to wear, making it ideal for demanding industrial applications.
