4 Leakage Classes Leakage Class Allowable LeakageValve Types Class IV 0.01% of rated valve capacity Intended for single port – valves with Metal to Metal seats Class VI The test fluid is air or nitrogen. Pressure is the lesser of 50 psig or operating pressure. The leakage limit depends on valve size and ranges from 0.15 to 4.00 ml per minute for valve sizes 1 through 6 inches

5 Port Diameter Class VI Allowable Leakage ml. Per minute Bubbles per minute

6 Valve Bodies Body material Size Operating Pressure Cast Iron (Section E2) lbs. Max. Ductile Iron (Section A & E2) lbs. Max Steel (Section E1) 1” and 2”4000 lbs. Max. 2”,3”, 4”, 6, 8”1500 lbs. Max

7 FEATURES: Motor over-travel protection switches Positioner full travel indication switches Explosion proof design Produces a linear output proportional to the pressure on the Pilot Spring Interchangeable Pilot Springs for 0-15, 0-30, or psig Output Pressure range At loss of electrical signal Output Pressure and the resulting valve position remain the same SPECIFICATIONS: Input Signal: 12 VDC pulse nominal, min. 11 VDC, max. 16 VDC Current 15EPC: 200 mA sustained max. 375 mA peak 30EPC: 235 mA sustained max. 360 mA peak 100EPC: 385 mA sustained max. 520 mA peak
