150LB DN700 Triple offset eccentric worm gear driven butterfly valve

DN700 Triple offset eccentric worm gear driven butterfly valve

Triple-offset butterfly valves offer the best sealing and longest life of all butterfly valve designs. Here are some of the reasons they are chosen:

• For the harsh conditions of critical process applications, steam isolation and temperature extremes, TOVs provide performance reliability and quality.
• The bi-directional zero leakage closure with a metal seat, even after extensive cycling, provides sealing integrity formerly associated only with soft-seated valves.
• Low torque from quarter-turn action permits smaller actuators and lower cost.
• Fire-tested designs per API 607, 5th Edition/ISO 10497-5 are available.
• Compact design means easier installation since valves are lighter and require less pipe ­bracing.

Valves with Tri-eccentric shaft and seals are appropriate for high pressure and temperature.
