Description
These single-port valves have cage guiding, quick-change trim, and balanced push-down-to-close valve plug action.
Valve configurations are as follows:
ED--Globe-style valve (figure 1) with m etal-to-metal seating for all general applications over a wide variety of pressure
drops and temperatures.
EAD--Angle version of ED, used to facilitate piping or in applications where a self-draining valve is required.
C-seal trim is available for ED valves, CL150, 300, and 600, in NPS 2-1/2, 3, 4, 6, and 8. C-seal trim is available for EAD
valves, CL150, 300, and 600, in NPS 3, 4, and 6.
With C-seal trim, a balanced valve can achieve high-temperature, Class V shutoff. Because the C-seal plug seal is
formed from metal (N07718 nickel alloy) rather than an elastomer, a valve equipped with the C-seal trim can be
appliedinprocesseswithafluidtemperatureofupto593_C (1100_F), provided other material limits are not
exceeded.
