Honeywell L91B1241 , Inc. Proportional Pressuretrol Controller, 10-300 psi

"10/300# PROP.#-TROL

"10/300# Proportional Pressuretrol Controller offers two precision proportional operators for controlling 2 functions (gas and liquid) from 1 set of program settings. The pressure range is 10 to 300 psi (70 to 20 bar). It is easy to install, with a 3-1/2" high x 6-1/4" wide plug-in DIN rail mount enclosure and 4" overall depth.

The Honeywell L91B1241 is a proportional pressuretrol controller, 10-300 psi. This pressure control valve uses trim air to control gas, steam and other gases. It is for use with the Maxitrol automated burner system for horizontal and vertical retort cooking equipment in poultry plants and meat processing operations.

The L91B1241 Proportional Pressuretrol Controller is designed for use with a variable displacement pump such as the Honeywell ZR series. The unit consists of a first stage regulator, second stage regulator and gauge manifold to control flow and pressure. The pressure settings can be manually set in 3 psi increments for wide flow and pressure range applications.

Allows monitoring and control of nitrogen flow in all types of flare header operation. The proportional trol provides full relaying capability for up to eight electric valves (10 amps per trol) with no need for additional relays. A built-in high/ low pressure switch allows detection of high or low differential pressure independent of the primary flow.

The L91B Series Proportional Pressuretrols are 3/4 in. NB linear or radial stem with a proportional pneumatic spring return and a balanced diaphragm that produces a highly consistent pressure regulation. The L91B is designed for use on most common gas and oil fired utility boilers and process burners where a lower pressure differential control is

This pro. proportional pressure control is suitable for air controls, liquid controls, vapor controls, process and special controls, and other applications where proportional action is desired."

Provides proportional flow control for 230V 3-phase motor applications. 0 to 10 vdc command signal to proportional valve (KF9210B) provides flow control to maintain static pressure at set point.
