Advanced Specialty Gas Equipment


REGULATORS FOR SPECIFIC APPLICATIONS
Models THP, THPS
Low Delivery Pressure, High Purity, Two-Stage Regulators

THP RegulatorThese metal diaphragm, cylinder regulators are specially designed to provide highly accurate pressure reduction of inlet pressures from a maximum of 3000 psig down to delivery pressures as low as 0.2 to 2 psig. The large effective diaphragm sensing area provides quick response, accurate and dependable regulation and long service life. The two-stage design provides constant outlet pressure regardless of changes in cylinder (inlet) pressures.

The Model THP is suitable for use with high purity non-corrosive gases, while Model THPS is designed for mildly corrosive gases that are compatible with the materials of construction.


Standard Features
  • Type 304 Stainless Steel Diaphragms minimize diffusion of air into regulator and eliminate "off gassing" associated with elastomeric diaphragms, thus maintaining gas purity.
  • Large 3 Inch Diaphragm in Second Stage, allows for accurate control of delivery pressures down to 0.2 psig.
  • Two-Stage Design ensures constant delivery pressure over varying inlet pressures.
  • Pressure Relief Valve protects regulator from overpressurization.
  • Dual Scale 0.1 psi / 0.01 Bar Graduations on Outlet Gauge allow for enhanced readability at extremely low settings.
  • Low Torque Multi-turn Handknob provides sensitive outlet pressure control.
