Advanced Specialty Gas Equipment

Model TSC TCS Regulator
Low Delivery Pressure, General Purpose,
Two-Stage Regulators

The Model TSC Regulator provides highly accurate pressure reduction of inlet pressures up to 3000 psig down to delivery pressures as low as 0.3 to 3 psig. The two-stage design provides constant outlet pressure regardless of changes in cylinder (inlet) pressures.

The Model TSC is suitable for use with noncorrosive gases where high purity is not required. Typical applications include low pressure purging, inert blanketing of chemical or flammable storage units, or control of fuel to burners.

Standard Features
  • Large 2 3/4" Diaphragm in second stage,allows for accurate control of delivery pressures down to 0.3 psig.
  • Two-Stage Regulator Design ensures constant delivery pressure over varying inlet pressures.
  • Sintered Metal Filters trap foreign matter, extend regulator life, and reduce maintenance.
  • 1-Ounce Graduations on a 2 1/2" Outlet Gauge allow for enhanced readability at very low pressure settings.
  • Outlet Metering Valve provides flow control.
