Industries & Applications
Midstream
Midstream valve applications not only require positive isolation, but some critical processes, such as molecular sieve dehydration, also involve high temperatures, frequent cycling, and dessicant residue. Union Tech Z4 Rising-Stem Ball Valves innovate upon the original “tilt-and-turn” design with features, such as the application of state-of-the-art MSBV hardfacing coating technologies to the sealing surfaces.
Downstream & Refining
The Downstream and Refining industries involve a diverse myriad of applications, oftentimes with unique technical requirements and specifications - and under severe service conditions. Union Tech valves are designed to be custom engineered to the exacting requirements for each application. For example, a metal seated Z4 Rising Stem Ball Valve may be appropriate for hydrogen compressor isolation, whereas a spray-and-fused chromium carbide coated Z2 metal-seated ball valve is optimal for a heavy oil and residue upgrading application.
Chemicals
The Chemical manufacturing industry involve processes under severe-service conditions - high temperature, high pressure, erosive, corrosive, high cycle, or any combination thereof. From the most abundant element in the universe (hydrogen) to the manmade and ubiquitous molecule polyethylene, Union Tech has developed engineered isolation solutions for the manufacture of these and other industrial chemicals.
Power Generation
Union Tech Z1 and Z1LW metal-seated ball valves were designed specifically for the severe-service conditions in fossil power plants involving superheated steam. Extended service life eliminates the need to repair valves during each outage, unlike gate and globe valves. The Z3 power valve system enables inline replaceability, eliminating need to cut-out existing and weld-in replacement valves. The Z2 provides engineered bespoke solutions specific to each plant.
Mining & Minerals
The Z2 Two-Piece Isolation Valve is a metal-seated ball valve engineered to be fully customizable for distinct applications in severe-service environments. The Z2 Mining Series valves have been specifically designed and optimized for the performance needs of mining applications – namely high temperatures and pressures with abrasive and corrosive slurries ubiquitous to pressure oxidation (POx) and high-pressure acid leaching (HPAL) autoclaves.
Upstream oil & Gas
Union Tech valves are the preferred isolation valves for the world’s EOR (Enhanced Oil Recovery) operators in heavy oil reservoirs. For these applications, Union Tech engineered a custom Z2 metal-seated ball valve design, capable of enhanced bi-directional shut-off and high cycle operation. These valves are widely used in the steam flow regulating systems, which mitigate phase splitting as well as in production manifolds.
