Sensus large capacity industrial service regulators are designed and built for commercial, industrial, and gas distribution use. As a result of the collar connection between the fully inter-changeable bodies and the diaphragm case, they have remarkable field versatility. They are right at home in such places as factories and foundries, district regulator stations, commercial laundries and laundromats, motels-hotels and apartments, bakeries, restaurants, schools, churches and hospitals.
The versatile 243 is used for all kinds of gas fueled equipment .. .boilers, burners, furnaces, ovens, heaters, kilns, engines, air conditioners, etc.
Remarkable field versatility results from the union connection between the fully interchangeable bodies and diaphragm-case assemblies. They are easy to install, adjust, inspect, and service in all piping arrangements.
Depth is affected by mounting position, flanged or screwed connections, diaphragm case size, and whether or not the unit is HP or standard.
Mounting Positions
These are multi-poised regulators, designed to that they can be mounted in any piping orientation.
Other Cases
243 Regulators are mainly used on natural gas. However, they perform equally as well on LP gas, nitrogen, dry CO2 , air and others. Contact us for special construction which may be available for certain corrosive gases. -
