Honeywell 1409 , Inc. D146 Differential Pressure Regulators

1-1/4" DIFFERENTIAL PRESSURE REGULA

HONEYWELL DIFFERENTIAL PRESSURE REGULATORS ARE USED TO

A 1/4"" differential pressure regulator assembled with high quality teflon and stainless steel materials. This DP is designed to regulate the pressure of a 4"" supply line to any number of balanced pair of ports. It is configured with 2 outlets and 3 ports.

Differential Pressure Regulators are available to control up to two stages of ventilation. They are ideal for applications in a wide range of industries, including:

The Honeywell D146 Differential Pressure Regulators, Part Number 1409, protect against the negative effects of inrush currents by reducing differential pressure to a safe level. Designed to be used on applications ranging from 5 psi up to 100 psi, this unit maintains the differential pressure at a safe level to ensure proper control and operation of heating and air conditioning equipment, altitude controllers, ventilation systems, and other systems that rely on the continuous flow of air or gas into a room.

The Honeywell D1409 Differential Pressure Regulator provides downflow protection of up to 250 FPM (20.6 m/s) of average water velocity when used with a Honeywell L14 Series or K14 Series combination valve. The D1409 can be mounted directly on a hot water heater, steam boiler or other similar plumbing system as either an up- or down-flow position. It has ganged adjustments and is supplied with three interchangeable limit switches.

The D146 Series is a pressure regulator designed to provide accurate and reliable differential pressure control. The D146 Series is suitable for a variety of applications such as, control of airflow or gas flow into a silencer, on/off control of diaphragm pumps or automated control of liquid level or flow in storage tanks and pipelines. The D146 Series has been designed for quick connect/disconnect operation with various tubing arrangements. Other features include regulate-by-wire capability, being easy to adjust using the programmable controller and external maximum/minimum setpoint adjustment.

Honeywell’s D146 series differential pressure regulators are the standard for HVAC and process control. The D146 Series is designed to:
