    (e.g. Type 3271 or Type 3277 Pneumatic Actuator) is designed to regulate the flow rate, pressure or temperature of liquids, gases or vapors. Only the Type 3251 Valve can be used after prior consultation and sizing for special appli- cations, such as oxygen, chlorine, phosgene, hydrogen sulfide (NACE), hydrogen or molten salt service.
  • Page 8 (see associated actuator documentation). When the valve is combined with a SAMSON Type 3271 or Type 3277 Pneumatic Actuator, the valve moves to a certain fail- safe position (see the 'Design and principle of operation' chapter) upon supply air or control signal failure.
  • Page 9 Start-up and shutdown procedures fall within the scope of the operator's duties and, as such, are not part of these mounting and operating instructions. SAMSON is unable to make any statements about these procedures since the operative details (e.g. differential pressures and temperatures) vary in each individual case and are only known to the operator.
