1. UNPACKING THE SMV MOTORIZED VALVE 1.1 Inspect Package for External Damage Your SMV Motorized Valve was carefully packed in a sturdy cardboard carton, with anti-static cushioning materials to withstand shipping shock. Upon receipt, inspect the package for possible external damage. In case of external damage to the package contact the shipping company immediately. 1.2 Unpack the Motorized Valve Open the carton carefully from the top and inspect for any sign of concealed shipping damage.
2. INSTALLATION 2.1 Primary Gas Connections Prior to connecting gas lines inspect all parts of the piping system including ferrules and fittings for dust or other contaminants. Be sure to observe the direction of gas flow as indicated by the arrow on the front of the meter when connecting the gas system to be monitored. Insert tubing into the compression fittings until the ends of the properly sized tubing home flush against the shoulders of the fittings.
During normal operation the valve remains in the last position as it is de-energized. After powering up, the valve will be automatically closed within the first 10 seconds and after that resumes control operation. PIN FUNCTION 1 2 3 4 5 6 7 8 9 (unassigned).

3. SPECIFICATIONS MATERIALS OF CONSTRUCTION: ALUMINUM MODELS: Aluminum housings and valve blocks, Viton® O-Rings, PFA closing pins. STAINLESS/PTFE MODELS: 316 stainless steel valve blocks, PTFE-lined Aluminum Housing blocks, Viton® O-Rings, and PFA closing pins. MAXIMUM FLOW RATES: 1000 sL/min (air), 28 L/min (water). CONNECTIONS: 3/8", 1/2", compression and 3/4" FNPT. ELECTRICAL CONNECTIONS: 9-pin "D" connector, located at the side of the valve.
SMV20-S/SMV30-S/SMV40-S: 316 stainless steel with VITON® O-rings seals; BUNA-N®, EPR or KALREZ® O-rings are optional. Aalborg® makes no expressed or implied guarantees of corrosion resistance of Motorized Valves as pertains to different flow media reacting with components of valves. It is the customers' sole responsibility to select the model suitable for a particular gas based on the fluid contacting (wetted) materials offered in the different models. 3.

4.2 Valve OFF Control (Open Collector NPN Compatible) It may be necessary or desirable to set the flow and maintain that setting while being able to turn the flow control valve off and on again. Closing of the valve (without changing the "speed"and "direction" control signals) can be accomplished by connecting pin 3 of the 9-pin "D" connector to COMMON ( power ground). The Motorized valve will be given the command to close indicated by a green light on top of the unit).
5. TROUBLESHOOTING 5.1 Common Conditions Your SMV motorized valve was thoroughly checked at numerous quality control points during and after manufacturing and assembly operations. It was carefully packed to prevent damage during shipment.
