Fisher easy-e Cryogenic Sliding-Stem Control Valves

1 easy-e Cryogenic sliding -StemControl ValvesFisher easy-e Cryogenic Valves are globe-style,single-port, Valves featuring stainless steelconstruction materials and fabricated extensionbonnets. Fisher ET-C and EWT-C Valves arepressure-balanced, whereas the Fisher EZ-C valve is anunbalanced design. These Cryogenic Valves aredesigned to provide throttling or on-off Control ofliquids and gases at Cryogenic temperatures as low as-198_C (-325_F).When required, these rugged Valves can reliablyprovide tight shutoff for special applications within thechemical and hydrocarbon processing industries, suchas certain liquefied natural gas high-capacity ET-C and EWT-C Valves withpressure-balanced trim allow the use of smaller,lower-cost actuators, reducing installed costs inhigh-pressure and high-flow-rate easy-e Valve FamilyThese Valves are part of the versatile easy-e family ofindustrial Control Valves .

The standard cage comes in twodifferent flow characteristics: Jequal percentageand Fisher easy-e CYROGENIC VALVE WITH EXTENSION BONNETW6370-1n EZ-C: Interchangeable, restricted-capacity trims andfull-sized trims match a variety of process flowdemands for highly-specialized applications. Thestandard plug is designed with three different flowcharacteristics: Jequal percentage, Jlinear, Cryogenic ValvesD102189X012 Product : easy-e CryogenicNovember 2020easy-e Cryogenic ValvesD102189X012 Product.

Balanced valve plug construction in theET-C and EWT-C Valves permits use of smaller,lower-cost Fisher Piping Economy Expanded end connections of EWSeries Valves may reduce the need for line swageswhile accommodating oversized pipingarrangements used to limit fluid flow Cryogenic Design Features The stainless steel valvebody and bonnet with fabricated extension aredesigned to meet low temperature unique metal-to-metal seat design providesrepeatable tight shutoff.

4 Reducing Rugged Metal Seat The metal-to-metal seat isdesigned and manufactured to provide long-lasting,reliable, tight shutoff at both ambient andcryogenic temperatures without the need forperiodic lapping. This reduces the need for softseats, even in applications with stringent Fugitive Emission Protection The optionalENVIRO-SEAL packing systems provide animproved stem seal to help prevent the loss ofvaluable or hazardous process fluids, and keepemissions below the EPA limit of 100 , these live-loaded packing systems canprovide long life and reliability at low temperaturesto help reduce maintenance costs and Thoroughly Tested Extensive Cryogenic testingduring the development of the valve design reducesthe need for expensive cold testing for mostapplications, which results in quicker delivery andgreater Easy Maintenance Quick-change trim, with aclamped-in seat ring, reduces the disassembly/assembly time.
