ZWICK TRI-CHECK Heavy Duty Metal Seated Check Valve
ZWICK Tri-Check Heavy Duty Metal Seated Check Valve
ZWICK's check valve TRI-CHECK combines all the benefits of their TRI-CON Series 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.
Also, the statically held gasket and the no pinned disc design are used in the Series TRI-CHECK. The TRI-CHECK is equipped with a hydraulic damper and a counterweight. The damper can be adjusted to the actual installation conditions in which the valve will be used.
Zero Leakage
The hydraulic damping system not only reduces the risk of pressure surges due to waterhammer because of its closing characteristic, but it also prevents the disc from slamming into the seat. Instead, the disc closes in a smooth movement which can be adjusted, so that the valve closes slowly in the last degrees of movement to protect the sealing parts. The Check Valve Series TRI-CHECK has proved to be the ideal non-return valve for single or multiple pump protection applications for the last two decades.
Another benefit of the valve is the variety of features. Besides the non-return function, the valve can be used as a combined check and isolating valve or as a check valve with power-assisted closing and opening.
Customized Solutions
The TRI-CHECK Series uses a seat design that is diagonal to the flange facing the body. As a consequence, the general flow path will be increased, so that the fluidic resistance of the valve will be decreased.
Another advantage is that the valve travel will be reduced so that the valve reaches its ideal position in the flow much faster. Zwick also uses the latest EFD simulation technology to optimize the design of the series TRI-CHECK and to achieve the best possible hydrodynamical characteristics.
