The ENVIRO-SEAL PTFE packing system 

is an advanced packing method that 

utilizes a compact, live-load spring 

design suited to environmental 

applications up to 750 psi and 232°C 

(51.7 bar and 450°F). While it is typically 

thought of as an emission-reducing 

packing system, ENVIRO-SEAL PTFE 

packing is also suited to nonenvironmental

applications involving 

high temperatures and pressures, 

yielding the benefft of longer, ongoing 

service life in both sliding-stem and 

rotary valves. See Figure 3.27.

Given the wide variety of valve 

applications and service conditions 

within industry, these variables (sealing 

ability, operating friction levels, 

operating life) are difffcult to quantify 

and compare. Figures 3.31 and 3.32 use 

an engineered approach in providing a 

relative evaluation of packing 

applicability and performance. But ffrst, 

proper understanding of the tables 

requires a clariffcation of trade names.

The single PTFE V-ring arrangement uses 

a coil spring between the packing and 

packing box ring. It meets the 100 ppmv 

criteria for sliding-stem valves, assuming 

that the pressure does not exceed 300 

psi (20.7 bar) and the temperature is 

between -18°C and 93°C (0°F and 200°F). 

Single PTFE V-ring packing does not 

come with low emissions criteria for 

rotary valves. It offers very good sealing
