Zwick – Tri-Con Triple Offset Valves (TOV)Enquire Now
BRAND: ZwickCATEGORY: Control Valves, Triple Offset Valves,
The Zwick Tri-Con triple offset valve is a metal seated valve with the widest laminated seal ring in the market today. Also known as triple eccentric valves or triple offset butterfly valves, the unique design and special features guarantee 100% zero-leakage performance even during extreme temperature variation and pressure peaks.
This is made possible by true cone-in-cone seating design which ensures frictionless opening and closing with lowest torques and without a break-away torque. The robust design makes the Tri-Con the ideal rotary solution for isolation, on/off and control in today’s demanding process industry.
The most popular configuration is double flanged even though wafer, lug, but weld and gate valve face to face are all readily available. Zwick’s proven design provides 100% tightness in gas services enabling it to be used for critical liquid and gas services. They are ideal for oxygen service and are available with steam jackets for molten sulphur or applications where media temperature must be kept with specific temperature parameters.
Full repair and reconditioning facilities are available at our Vereeniging and Durban branches. There are hundreds of valves installed in South Africa today in industries like synthetic fuels, oil & gas, chemical and power generation.
