RegO Twin Stage Automatic Changeover Regulators

Application:

These combination automatic changeover, two stage regulators are especially suitable for homes, mobile homes, cottages, construction and other portable two cylinder installations. Empty containers may be replaced without interrupting customer’s gas service.

Features:

• Automatic changeor switches from “service” to “reserve” cylinder automatically without interrupting service.
• The Second Stage Incorporates wide bonnet drip lip vent to guard against freeze-up when properly installed.
• With 15 PSIG inlet pressure, the second stage regulator is designed to not pass more than 2 PSIG with the seat disc removed.
• Allows "reserve" cylinder to supplement the flow of gas from the "service" cylinder during extreme load or severe cold conditions.
• Incorporates molded diaphragm in second stage regulators.
• Integral indicator gauge.
• Change over knob and indicator are integral to the first stage.
• Select brown finish on first stage.

High Pressure Industrial/Commercial Pounds-to-Pounds Regulators

Designed to reduce propane gas container pressure down to between 3 and 100 PSIG. Ideal for liquid or vapor service, they can be used in a variety of applications, including salamander heaters, weed burning toches, fish cookers, tar pot heaters and other industrial type services.

FEATURES:

• Provides high capacity performance at a reasonable price
• Suitable for both liquid and vapor service.
• Compact design provides easy installation
• Consistent delivery pressure, especially in cold weather, helps assure maximum performance from the second stage regulator

High Pressure/High Temperature Industrial/Commercial Pounds-to-Pounds Regulators

Application:

Designed to reduce LP-gas container pressures to between 3 and 50 PSIG. Ideal for crop drying, heat treating, asphalt batch mixing and other large industrial and commercial load application utilizing high temperature LP gas or high temperature atmosphere under conditions up to 300°F. Also ideal as a first stage regulator in large multiple operations.

FEATURES:

• Special diaphragm and seat materials are suitable for up to 300°F. temperatures.
• Large nozzle and straight through flow provides high capacity and resistance to freeze ups.
• Suitable for both liquid and vapor service.
• Can be fitted with high pressure gauge in 1.4" F. NPT port. Engineered Controls International, Inc. recommends that these gauges use silver braze rather than soft solder construction.
