Product Overview
The Tartarini PS/79 Series Valve Parts are genuine replacement and maintenance components engineered for Tartarini pilot-operated gas pressure regulators and relief systems. Manufactured by Emerson under the Tartarini brand, the PS/79 series pilot system serves as the high-precision pneumatic control heart for primary gas reduction units, including Tartarini FL, Cronos, and MBN series pressure regulators. These genuine valve parts, overhaul kits, and soft goods restore original dynamic sensitivity, pressure control accuracy, and shutoff tightness across critical natural gas infrastructure.
Comprising precision-molded elastomeric diaphragms, vulcanized valve pads, resilient O-ring seals, filter assemblies, and stainless steel internal trim components, the PS/79 series parts are designed to withstand severe gaseous flow velocities and cyclic operating pressures. Manufactured from high-grade nitrile rubber (NBR), fluoropolymer elastomers, and corrosion-resistant alloys, these parts eliminate internal gas leakage, prevent pilot hunting, and maintain calibrated outlet setpoints under fluctuating pipeline flow rates. They are essential for routine scheduled maintenance and emergency overhauls in natural gas transmission city gates, district regulating stations, industrial gas burner trains, and power generation fuel skids.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
