The Z1 Unibody Power Valve is a one-piece metal-seated ball valve engineered for clean steam severe-service (high-pressure, high-temperature) environments, including power generation and critical on/off applications.

The Z1-LW is a one-piece lightweight ball valve designed for clean steam severe-service (high-pressure, high-temperature) environments.  With one integral SW end, the compact design of the Z1-LW valve weighs 50% less than typical flanged valves of the same pressure class.

The Z2 is a two-piece metal-seated ball valve engineered for severe-service environments for use in critical applications, including chemical / petro-chemical, refining, power, and mining.

The Z3 Power Valve System consists of a modified Z1 valve and a pair of end connections and enables inline replaceability, which eliminates the need to cut-out existing and weld-in replacement valves, while retaining all features of the Z1 Unibody Power Valve.

The Z4 Rising Stem Ball Valve employs a tilt-and-turn design enabling frequent cycling, zero-leakage, and low torque operation.  This valve is engineered to replace traditional ball, gate, and plug valves in gas processing plants using molecular sieve systems for switching service, pipelines, gas transmission, and other high performance applications requiring frequent cycling with positive shutoff operation.
