Since the 1980s, Union Tech has been manufacturing valves and/or valve components. The Z-Series Valves were jointly developed by our team of engineers and seasoned valve experts; as newer technologies in advanced materials and manufacturing methods were introduced over the decades, Union Tech incorporated these state-of-the-art technologies vis-a-vis design improvements throughout the Z-Series product line.
Union Tech utilizes advanced engineering techniques, such as finite element analysis (FEA) and comprehensive flow analysis and combines it with pragmatic “know-how” drawn from decades of product experience to ensure that every valve is optimized for its intended application. Our engineering team is always available for support with upfront materials selection, piping and instrumentation diagrams (P&ID), and general onsite operations.
The Z1 Unibody Power Valve is a one-piece, metal-seated ball valve engineered for dependable zero leakage performance for superheated steam in high-pressure, severe-service applications, including power generation and critical on/off applications.
The Z1LW Lightweight Unibody Power Valve is a one-piece, metal-seated ball valve engineered for dependable zero leakage performance for superheated steam in high pressure, severe-service applications, including power generation and critical on/off applications.
The Z2 Two-Piece Isolation Valve is a metal-seated ball valve engineered to be fully customizable for specific applications in severe-service environments, including chemical / petrochemical, refining, power, and mining that require dependable zero leakage performance.
The Z3 Power Valve System is engineered for dependable zero leakage performance in high-pressure, severe-service applications, including power generation and critical on/off applications. Consisting of a modified Z1 valve and a pair of SW or BW end connections, replaceability.
The design and performance advantages of the Z4 Rising Stem Ball Valve enable it to replace traditional ball, gate, and plug valves in isolation applications, such as gas processing plants using molecular sieve systems for switching service, pipelines, gas transmission.
Union Tech Z4 Pneumatic Diaphragm Actuators are designed specifically for smaller-sized Union Tech Z4 Rising-Stem Ball Valves; mechanical operation of the actuator is matched and tuned precisely to that of the Z4.
Union Tech Z4 Pneumatic Piston Actuators are designed specifically for larger-sized Union Tech Z4 Rising-Stem Ball Valves.
