The Emerson Fisher 133 Series is a premium line of direct-acting pressure regulators designed to deliver accurate, low-maintenance pressure control for industrial and commercial applications. As a cornerstone of Fisher’s pressure management solutions, the series includes two specialized models: the 133L-6 Pressure Reducing Valve and the 133H-3 Pressure Regulator, each optimized for distinct operational needs.

Built on a direct-acting mechanism, these regulators operate without external power—using inlet media pressure to adjust the valve position and maintain consistent outlet pressure. This design ensures rapid response to pressure fluctuations, making the 133L-6 ideal for reducing high inlet pressures to stable, lower levels in systems like HVAC, fuel gas distribution, and water treatment. The 133H-3, meanwhile, excels in general pressure regulation tasks, such as maintaining set pressures in industrial process lines, compressed air systems, and utility services.

Key advantages include a compact, durable construction resistant to corrosion and harsh environments, compatibility with gases, liquids, and steam, and precision-machined components for long service life. Fisher’s rigorous engineering ensures compliance with industry standards, minimizing downtime and total ownership costs.

For businesses needing reliable, efficient pressure control, the Emerson Fisher 133 Series—including the 133L-6 and 133H-3—offers a cost-effective, easy-to-install solution that balances performance and durability.
