HARRIS REGULATOR MODEL 847, PIPELINE REG, 0-400KPA, NITROGEN

Product Description

The Harris Model 847 Nitrogen Pipeline Regulator (Part No. 847400NIT) is a high-flow, single-stage line regulator engineered to deliver precise, stable pressure control for nitrogen distribution in industrial, laboratory, and pipeline applications. Built on the proven Model 847 platform with a very large diaphragm for smooth, accurate pressure adjustment and a forged, high-quality brass body for long service life, this regulator is purpose-built for reliable nitrogen gas handling in fixed pipeline installations.

With an adjustable outlet pressure range of 0–400 kPa, the 847400NIT gives operators fine control over downstream nitrogen delivery, making it well suited to purging, blanketing, pressure testing, and general nitrogen supply line regulation. It features a rear inlet with 1/4" NPT-F connection and a 5/8" UNF-M RH outlet connection, and is manufactured to comply with AS4840.

Key Features

• Gas Service: Nitrogen (N2) pipeline regulation
• Outlet Pressure Range: 0–400 kPa, fully adjustable
• Inlet Connection: 1/4" NPT-F, rear-entry configuration
• Outlet Connection: 5/8" UNF-M, right-hand thread
• Large easy-to-read 63mm diameter gauge for clear, accurate pressure monitoring
• Built-in, tamper-proof, self-reseating safety relief valve for added protection
• Very large diaphragm enabling smooth, highly accurate pressure adjustment
• Body Construction: Forged brass for durability in continuous industrial use
• Standards Compliance: AS4840 (Australian Standard for gas regulators)
• Origin: Manufactured in Europe
• Design Type: High-flow, rear-inlet pipeline/line regulator (not a cylinder-mount regulator)

Typical Applications

• Nitrogen purging and blanketing systems
• Pressure testing of pipework and HVAC/refrigeration lines
• Fixed nitrogen pipeline distribution in workshops, labs, and industrial facilities
• Secondary/line-pressure regulation downstream of a bulk nitrogen supply or manifold

Why Choose the Harris 847400NIT

Harris regulators are a long-standing choice in industrial gas control for their robust brass construction, oversized diaphragms, and consistent outlet pressure regulation under varying inlet conditions. The Model 847's rear-inlet pipeline design makes it ideal for permanent in-line installation, while the 0–400 kPa adjustment range covers the needs of most nitrogen purging, testing, and process applications. Its AS4840 compliance makes it a suitable choice for facilities requiring certified gas regulation equipment.

Specifications Summary

Note: As with all pressure regulation equipment, confirm maximum inlet pressure and flow rate requirements against your specific pipeline system before installation, and always have gas equipment installed and serviced by a qualified technician.
