Model 61H F/R Booster Relay INTRODUCTION Designed to meet high-speed control applications, the Model 61H F/R Booster Relay produces a high volume boosting action. Its primary purpose is for use with valve positioners, although it can be used by itself for the high volume of air it can control.
SD61H-1 Blow out all piping before connections are made to prevent the possibility of dirt or chips entering the relay. Use pipe sealant sparingly, and then only on the male threads. A non-hardening sealant is strongly recommended. Connect the relay to a source of clean, dry, oil-free instrument air. See Instrument Air Requirements below. CAUTION Pressure in excess of 100 psi to any connection may cause damage to the relay.
