WEGA-SP Regulators - Pressure Reducing For other materials or modifications, please consult TESCOM. MEDIA For inert and corrosive gases. For high purity calibration gases / gas mixtures. OPERATING PARAMETERS Maximum Inlet Pressure 2900 psig / 200 bar Outlet Pressure Ranges 7.25—21.75, 7.25—58, 14.5—101.5, 14.5—145 psig 0.5-1.5, 0.5-4.0, 1.0-7.0, 1.0-10.0 bar Leakage Rate Against Atmosphere 2 x 10-8 atm cc/sec He WEGA-SP with manual connection & O-ring Nominal Flow Capacity 10 m3/h (according to pressure and used gas) Cv = 0.06 Cv = 0.15 Cv = 0.24 optional Temperature Range Seat PCTFE: -25°C to +60°C [-13°F to 140°F] Seat TEFLON® PFA 350/PTFE: -25°C to +74°C [-13°F to 165°F] Optional Higher outlet pressure up to 500 psig / 35 bar Relief valve with captured venting Shut-off and metering valve at outlet Absolute pressure version MEDIA CONTACT MATERIALS Applications • Pressure reduction of corrosive or toxic gas from pressure cylinders by inducting the purge gas. The process gas will be effectively eliminated from the regulator and the cylinder connection. • Ideal for use in laboratories. Body 316 Stainless Steel Diaphragm 316 Stainless Steel, Nickel Alloy (Hastelloy®) Seat PCTFE, PTFE Purging Seat EPDM, FKM Features and Benefits • Compact design without externally mounted purging device. Reduces weight, internal volume and installation length. • Effective purging due to integrated purge valve and check-valve, low purge gas consumption, minimized risk of corrosion. OTHER Inlet Connection According to national standards like DIN477-1, CGA V-1 and BS341 Outlet Connection 1/4" NPTF female or compression fitting Hastelloy is a registered trademark of Haynes International, Inc. ® TESCOM WEGA-SP (single stage) with integrated purge function includes shut-off function and check valve and is specially designed for use with corrosive or toxic gases and gas mixtures. The integrated purging device effectively removes residual moisture, aerial oxygen and remaining process gas. • Reduces consumption of expensive calibration gases and test gases because residual moisture and external gases are eliminated before starting-up the process. • Optional tied diaphragm "positive seal" design provides additional shut-off assistance for corrosive gases. • Valve trim and diaphragm made of Hastelloy® are available for extended life by reducing corrosion. • Minimized helium leak rate due to reduced number of connections.
