Spirax-Sarco 59607 Press Pilot 30067439-890 or mechanical resistance in theThe Spirax Sarco 59607 is a pressure pilot specifically engineered for the 25P Series Pressure Reducing Valve (PRV). Constructed from durable cast iron, this 25P Press Pilot is designed to manage downstream pressure ranges between 20 and 100 psi (Blue Spring configuration). In steam system regulation, this pilot functions as the brain of the main valve, sensing downstream pressure changes and modulating the main diaphragm to maintain a consistent set
