Our Cast Iron Lugged Butterfly Valve SS Disc Table E Lever NBR Seat is a high-quality flow control solution designed for durability, precision, and ease of operation. Engineered to meet industrial standards, this valve combines a robust cast iron body, corrosion-resistant stainless steel disc, and a resilient NBR (Nitrile Butadiene Rubber) seat for dependable performance in water, air, and oil applications.
Product Overview
This lug-type butterfly valve features a rugged cast iron body with threaded lugs, allowing secure installation between flanges while maintaining pipeline integrity. The Table E lever provides smooth manual operation with clear open/close indication. The NBR seat ensures a tight seal against various media, including water and hydrocarbons, making this valve suitable for general industrial use.
Construction & Design
Constructed with precision and built for long service life, the valve’s stainless steel disc offers superior resistance to corrosion, while the cast iron body ensures mechanical strength and stability under pressure. The NBR seat provides excellent sealing performance with oil-resistant properties, ideal for moderate temperature and pressure conditions. The lugged design enables easy installation and maintenance without disturbing the entire pipeline.
