The Zwick Tri-Con offers the widest laminated seal ring in the market today, made possible by true cone-in-cone seating design which assures a frictionless opening and closing with lowest torques and without a break-away torque. This unique and robust design makes the Tri-Con rotary process valve the ideal solution for isolation, on/off and control in today’s demanding process industry. Zwick’s proven design provides 100% tightness in gas services enabling it to be used for critical liquid and gas services in synthetic fuels, oil & gas, chemical, power and other global industries. These valves are designed for temperatures up to 815°C as well as cryogenic services.
