TRI-CHECK check valves utilize the same triple-offset geometry as TRI-CON butterfly valves, ensuring frictionless operation that minimizes wear and extends service life. Its laminated seal and floating self-centering disc provide bubble-tight shut-off with 100% tightness, while the adjustable counterweight and hydraulic damper reduce pressure surges, protect sealing components, and enhance valve longevity.
