The 1/4" RC200 (807) serves as a direct replacement for SN G40137. This process control valve features a cast straight-through valve body made of 316 SST with G 1/4" female threaded connections. It includes a standard 316 SST bonnet with PTFE/PFA V-ring spindle packing and is assembled using Dow 111 silicone-containing mounting grease. The internal trim is size 'J' offering equal percentage characteristics with a Kvs of 0.043, utilizing a 316 SST plug and seat. Operation is driven by a Type 754 pneumatic actuator featuring a fail-close spring action with a 0.2-1.0 barg signal range and a G1/8 connection. Control is managed via a Samson 3730-0-8 i/p positioner accepting a 4-20mA signal, supplied at 4.0 bar through a G1/4 air connection. The positioner carries hazardous area certifications including 2Ex nA, 2Ex ic, and 2Ex tc ratings.
