Pressure-Core™Stem Seal

PGI's Teflon® Pressure-Core™ Stem Seal offers advanced sealing technology in standard instrument valves and manifolds, saving you both time and money. Compared to competitive packing designs, the Pressure-Core™ Seal offers virtually leak-free performance with no maintenance requirements. To support this claim, we tested the Pressure-Core™ Seal against the leading manufacturer's design. The tests simulated harsh plant operating environments and were performed by an independent laboratory in accordance with EPA Method 21. Detailed test results are available that prove our Pressure-Core™ Seal clearly outperformed the leading manufacturer's design. The Pressure-Core™ Seal consists of an outer Teflon® shell with an elliptical shaped Viton® O-ring core. The encapsulated core is "liveloaded" and provides constant outward pressure against the Teflon® shell, which flexes under pressure like an O-ring. The Teflon® shell offers the desired chemical resistance without Periodic gland tightening as in conventional designs. Our test results indicate that you can have a reliable, affordable and virtually leak-free valve requiring no costly, time-consuming maintenance. We stand behind our claim with a five year warranty, far exceeding the industry standard.

Hot-Shot™ Heated Enclosure

PGI's Hot-Shot Heated Enclosures will help you comply with the new standard "Collecting and Handling of Natural Gas Samples for Custody Transfer" - API 14.1. This newly published, updated standard requires that the temperature of the sampling equipment be kept above the hydrocarbon dew point of the gas being sampled, which typically requires heating of the equipment, and thus insures a more accurate measurement.

	Sample Pump, Probe and Cylinder heated above hydrocarbon dew point
	Regulated enclosure temperature with overheat protection
	Class 1 Division 1 Approved
	Heater supply gas taken from sample probe
	Complies with NEW API 14.1 requirements for heated sampling
