Ei 49816283C In-Line Piloted Unloader Valve with Relief for Ingersoll Rand T30 Gas-Powered Compressors

Overview

The Ei 49816283C inline piloted unloader valve with relief valve is a compact brass assembly designed to integrate with Ingersoll Rand T30 gas-powered compressors. It combines unloading, overpressure protection, and a throttle-control port in a single, ready-to-install unit. Its inline footprint is suited for tight spaces in busy workshop environments, helping streamline routine starting and unloading cycles.

Engineered to be durable and reliable, this valve merges three essential functions in one component, reducing the need to source multiple parts while keeping a clean, straightforward flow path from the pump to the tank.

Key features at a glance

• Brand new Ingersoll Rand inline piloted unloader valve with relief valve, part number 49816283-C.
• Inlet: 5/8" inverted flare; Tank connection: 1/2" female NPT.
• Solid brass construction, manufactured in the USA.
• Includes a 325 PSI relief valve and a 1/8" NPT throttle control valve port.
• Factory-set ON/OFF throttle control: 145–175 PSI.
• OEM part designed for use with Ingersoll Rand T30 gas-powered compressors.

Why this matters in your workflow

Unloading valves help manage pressure during startup and unloading cycles, potentially reducing cycling stress on the pump and tank. The integrated relief valve provides a safety margin against pressure spikes, while the throttle port offers a pathway to add control functionality when needed. The brass body and USA manufacturing denote a focus on durability and consistency in common shop pressures.

System compatibility and setup tips

• Top port: 5/8" inverted flare connects to the main line from the compressor pump.
• Bottom port: 1/2" female NPT connects to the tank or to a corresponding fitting.
• Throttle control port: 1/8" NPT accepts a throttle control valve to define on/off behavior.

Real-world use scenarios

Ideal for shops using Ingersoll Rand T30 gas-powered compressors where a compact, inline component can simplify plumbing and maintenance. The 325 PSI relief valve offers peace of mind for occasional pressure surges, while the 145–175 PSI throttle setting provides a usable range for typical operating conditions without overspecifying the system.

Quality and origin

Crafted from solid brass and built in the USA, this OEM-style valve emphasizes longevity in demanding environments while keeping compatibility with familiar Ingersoll Rand configurations.
