BRAND: ZwickCATEGORY: Triple Offset Valves

The Zwick Tri-Jack is the Tri-Con triple offset valve fitted with steam jackets for process where media may solidify or chrystalize if the product temperature drops below a specific point.

Also known as triple eccentric valves or triple offset butterfly valves, the unique design offers zero leakage which 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.

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.
