• UL Listed
• ULC Listed
• FM Approved
• 4″-14″ VALVES
• 16″-24″ VALVES

Application

• Valve indicator for buried and in-accessible valve

BUTTERFLY VALVES

 

Designed specifically for the waterworks industry, Lineseal butterfly valves offer the ruggedness and reliability required for buried service and performance. Lower head loss means getting the most from your pumping station dollar. Lower torques mean less costly actuation packages, and the maintenance-free design helps keep your budget under control.
