The Fisher 133HP is a high-performance direct-operated pressure reducing regulator designed for industrial and commercial gas applications, such as furnaces, burners, and boilers. Its advanced balancing system ensures accurate pressure control even under fluctuating inlet pressures, optimizing combustion efficiency. Key features include a wide inlet pressure range up to 150 psig (10.3 bar) and outlet pressure settings from 2–60 psig (0.14–4.1 bar) across seven ranges. With a maximum flow rate of 9,970 Nm³/h and ±2.5% precision, it offers reliable performance for natural gas, LPG, and air.
Constructed with cast iron or steel bodies, the 133HP supports multiple connections: 2” NPT, ANSI 125FF, or 150RF flanges. It withstands temperatures from -29°C to 66°C and includes benefits like in-line maintenance, bubble-tight shutoff, and minimized spring/diaphragm effects. Ideal for critical processes requiring fast response and durability, the 133HP is a trusted choice for enhancing system safety and efficiency.
