(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' section) upon supply air or control signal failure.

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.
If a device contains a substance listed as a substance of very high concern on the candi- date list of the REACH regulation, this is indicated on the SAMSON delivery note. − Special mounting and operating instructions are available for the Type 3251 Globe Valve for molten salt service u EB 8052-1.
