This is a new Spence K1TH811-60RH pneumatic globe control valve, 2-inch pipe size, with a bronze valve body and a large-diaphragm pneumatic actuator — consistent with what is visible in the photos and confirmed by the Grainger cross-reference label 1RXC8 identifying it as a 2 in. Pneumatic Globe Control Valve. The nameplate visible on the unit indicates body material BRZ (bronze), PMO (maximum operating pressure) of 400, TMO of 100, actuator size 10, reverse-acting (REV) action, and PMA of 20, pointing to a spring-return diaphragm actuator with a 3–15 PSI signal range operating reverse-acting (air-to-close / fail-open). The globe valve body features NPT female threaded end connections on both ports, a single-seat design with a threaded trim plug, and a brass valve stem, consistent with Spence E-Series globe control valve construction used in steam, condensate, and HVAC process control applications. The unit is assembled in Mexico per the nameplate and is presented in new condition with port protectors installed.
