3200300 - Harris 8700 High Pressure Nitrogen Regulator, 0-1500 PSIG Delivery

Technical Overview of the Harris Model 8700-1500-580

The Harris Model 8700-1500-580 is a specialized single-stage high-pressure regulator designed for applications requiring delivery pressures significantly higher than standard industrial regulators. Engineered for precision and durability, this unit is capable of delivering pressures ranging from 0 to 1500 PSIG. It is constructed from solid brass barstock for both the body and bonnet, providing a robust housing that withstands the rigors of industrial environments better than forged alternatives. The regulator is equipped with a CGA-580 inlet connection, making it compatible with standard inert gas cylinders such as Nitrogen, Argon, and Helium.

At the core of the Model 8700's performance is its one-piece encapsulated valve design. This module utilizes a PCTFE (Kel-F) seat, a material chosen for its high compressive strength and resistance to deformation under high pressure. To ensure the longevity of this critical sealing surface, Harris has integrated a 10-micron sintered filter directly into the valve assembly. This filter effectively traps particulates that could otherwise score the seat and cause creeping or failure. The regulator also features a urethane diaphragm, which offers superior flexibility and sensitivity compared to stainless steel in this specific high-pressure configuration, allowing for accurate pressure control across the delivery range.

The outlet is configured with a 1/4-inch NPT female thread and comes supplied with a stainless steel 1/4-inch tube fitting, facilitating direct connection to high-pressure hoses or tubing systems. Dual-scale 2.5-inch brass gauges provide clear readouts of both cylinder contents and delivery pressure in PSI and BAR. The ergonomic ABS plastic knob allows for smooth, low-torque adjustment, ensuring precise setting of the output pressure. This model conforms to CGA E-4 standards for gas pressure regulators, ensuring compliance with industry safety and performance benchmarks.
