Company profile

Zwick is a leading manufacturer of metal-seated triple offset butterfly valves known as series TRI-CON, the check valves, called TRI-CHECK and the TRI-BLOCK series, Zwick’s Double Block and Bleed Design.

The triple offset butterfly valves are specially designed for critical services where they are used as shut off and control valves. The in-house design enables offering customized solutions for individual applications like the global Industries of Oil and Gas, Chemical, Petrochemical, Energy, Offshore and Steel. Zwick valves are used for industrial and exhaust gases, liquids, hot water or steam at lowest as well at high temperature zones up to 815°C.

TRI-CHECK

The check valve TRI-CHECK combines all the benefits of the Series TRI-CON in a non-return valve. Triple-offset design with a wide seat angle and a true cone in cone, no rubbing while moving and absolute zero leakage performance. The TRI-CHECK is equipped with a hydraulic damper and a counter weight. The damper can be adjusted to the actual installation conditions in which the valve will be used.

TRI-BLOCK

The Double Block and Bleed design features every technical advantage which the series TRI-CON has plus there is a true double block and bleed feature which delivers zero leakage. By using this design, the former two valve system with a spool piece becomes obsolete. With Zwick’s unique design of the linkage between the two shafts, the user is able to actuate both shafts with only one actuator and reach zero leakage with the two available sealing surfaces.

TRI-SHARK

TRI-SHARK control valves are able to achieve a nearly equal percentage inherent characteristic which greatly extends the control rangeability. Furthermore they offer great advantages in the field of cavitation reduction and noise attenuation, as well as in dynamic torque reduction. They are suitable for a wide range of services, from cryogenic temperatures till -196°C up to +815°C, including liquids, gases and steam.
