Page 5: Safety Instructions And Measures
SAMSON does not assume any liability for damage resulting from the failure to use the device for its intended purpose or for damage caused by external forces or any other external factors. - Page 6 The Type 2489 Pressure-independent Control Valve (PICV) with an electric actuator with fail- safe action moves to a certain fail-safe position upon supply voltage failure. The fail-safe action of SAMSON actuators is specified on the actuator nameplate. When relieved of pressure, the valve with an open restriction without electric actuator and Type 2430 Thermostat is opened by the force of the set point springs.
- Page 7 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.
