220 pilot-operated gas pressure regulators 1–4 inches, inlet up to 69 kPa, up to 1416 m³/h
Country: Germany · Model: 220
Pilot-operated gas pressure regulators 220D, 220E, 220G and the flanged 220J with 1–3 inch connections (220J has a 4 inch flange), inlet pressure up to 68.9 kPa, flow up to 1416 m³/h. The main diaphragm is loaded by gas from a built-in pilot, so the regulator holds a higher outlet pressure than spring models of the same size. The main application is industrial furnaces and drying chambers with a large gas flow.

Description
The main diaphragm of the 220 regulator is loaded not by a spring but by gas, which a small pilot regulator in the upper body holds accurately. When the pilot spring changes the pilot's outlet pressure, the outlet pressure of the main regulator changes proportionally, which simplifies setting. Connections of 1–3 inches with NPT or ISO 7-1 threads are on 220D, 220E and 220G, and 220J has a 4 inch class 125 lb flange. The body is aluminium and mounting is vertical only. Maximum inlet pressure is 10 psi (68.9 kPa), the emergency limit 25 psi (170 kPa), capacity up to 50 000 cubic feet per hour (1416 m³/h), and ambient temperature from −40 to +93 °C. The body has three positions for pressure tapping, and a fourth is used for an impulse connection. The pilot is supplied with interchangeable color-coded springs, with a range from 1.0 to 12 inches of water column for pilots R12 and RV20L and above. For the European market the 220 series is not listed in EU catalogs; the data are taken from the 7th edition North American catalog (2025).
How to choose
220 is chosen when a large gas flow at increased outlet pressure is needed, for example on the burners of industrial furnaces and dryers. The size is set by the connection diameter from 1 to 3 inches or the 4 inch flange on 220J. For smaller flows and inlet pressure up to 20 kPa take RV53–RV111, for inlet pressure up to 100 kPa 325, and for strongly varying inlet pressure R/RS or 210.

FAQ
How does the 220 regulator differ from spring-loaded ones?
The main diaphragm is loaded by gas from the pilot instead of a spring, so outlet pressure is higher than in spring models of the same size.
What is the maximum flow of the 220 regulator?
Up to 50 000 cubic feet per hour, that is 1416 m³/h.
What inlet pressure does the 220 series allow?
10 psi (68.9 kPa) in operation and 25 psi (170 kPa) as the maximum emergency pressure.
Which gases is the 220 regulator suitable for?
For natural, manufactured and mixed gases, liquefied petroleum gas and LPG-air mixtures.
Is the 220 series listed in European catalogs?
No, the data are taken from the 7th edition North American catalog (2025).
