Sensus Regulator 243 RPC, 243 RPC-A, 243 RPC-B
Sensus 243 RPC Industrial Combustion Pilot Operated Gas Regulator
 

Genuine, pilot-operated regulators use the same relay operation principle as the well-known 441-VPC. Use of this principle results in exceptionally precise regulation. The 243-RPC is accurate within ±0.5% absolute outlet pressure from minimum to wide-open flow.

Relay operation also minimizes the effects of inlet variations. Accuracy is largely unaffected by swings in inlet pressure.

The 243-RPC is made for fixed factoring, pressure factor measurement, pressure compensated metering and other applications requiring exceptionally precise pressure control. Wherever requirements call for maximum accuracy at minimum cost, the 243-RPC makes an excellent choice.

Available Pipe Sizes: 1-1/4", 1-1/2", 2" NPT Screwed and 2" Flanged
Interchangeable Orifices: 1/4" - 1-1/4"
Body: Cast Iron (ASTM A126 Class B)
Diaphragm case: Die Cast Aluminum Alloy
Orifice and Stem: Brass

Sensus 121 RPC Industrial Pilot Operated Gas Regulator
 

The 121-RPC is a genuine Pilot Operated Regulator (Relay Principal of Operation).

The relay principal means exceptional precise control. Accuracy is largely unaffected by changes in the inlet pressure.

The control line is piped to both the inlet and main regulator. The loading pressure to the main regulator varies with the downstream pressure resulting in precise regulation.

The 121-PL is a pressure loaded, Pilot Operated Regulator. The pressure loading of the diaphragm minimizes droop caused by spring and diaphragm effect, thus providing more accurate control. The outlet set pressure is controlled by adjusting the pilot regulator of the 121-PL.
