These 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.

• 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.
