Valves & Piping

Mechanical operations, especially in process or cooling applications, rely heavily on interconnectivity to run efficiently and safely. Stellar provides a complete range of engineering, fabrication, installation and maintenance of process, mechanical, refrigeration and HVAC systems piping to the food, energy, pharmaceutical, healthcare and petrochemical industries. Piping, valves and other flow-related components between compressors, chillers, evaporators, turbine inlet air coolers, condensers and process applications require more than a good weld and proper fastening by an ordinary contractor. Stellar has the resources, experienced engineers and technically advanced and trained mechanical fitters to handle the most complex piping requirements. Either at the jobsite or at Stellar's own fabrication facility, expert pipe fitters assemble and build piping systems, bridgework, skids and structural steel supports. Our pipe fitters are certified arc, heli-arc, orbital and Mig welders and have worked on many types of materials, including sanitary stainless steel systems, carbon steel, chrome moly, cast iron, plastics, fiberglass, copper, brass and aluminum.

We ensure that each fabricated system will meet the tightest tolerances and all predefined codes. These codes prescribe requirements for the materials, design, fabrication, assembly, erection, test and inspection of refrigerant, heat transfer components and secondary coolant piping to meet standards set out by ASME, UL, ANSI-NFPA, ASHRAE and military specifications. Stellar has created its own piping program that is set above minimum industry standards for refrigerant recovery, weld testing, valve repair and testing, backflow testing and repair, fire protection system testing and repair.

The failure of a valve can cause an entire system to fail, resulting in high costs or even a potentially dangerous release. Properly working control valves in a refrigeration system offer operators peace of mind during start-ups, shut-downs, preventative maintenance, emergency response and system troubleshooting. Stellar stocks and distributes one of the largest refrigeration system valve inventories in the U.S., with each valve sold manufacturer-tested, tagged and warranty-backed based on capacity, flow loop and other standards related to specific systems.

Stellar offers 24 hour/7 day a week availability, scheduled or emergency installation and the most competitive pricing on solenoid valves, pressure regulators, shut-off valves, check/isolation valves, safety relief valves, liquid level controls, flow regulators, strainers and purgers.
