ASCO 8210G094-120/60,110/50 Solenoid Valve Instruction Manual

1. Product Overview

The ASCO 8210G094-120/60,110/50 is a brass body, pilot-operated, general service solenoid valve designed to permit and shut off fluid flow. This 2-way valve operates as Normally Closed (NC), meaning it is closed when de-energized and opens when energized. It features a durable brass construction and Nitrile Butylene sealing, suitable for various applications including liquid, corrosive, and air/inert gas service. Key features include long service life, low internal leakage, and high flow capabilities.

2. Safety Precautions

Always observe the following safety precautions to prevent personal injury or damage to the equipment:

• Disconnect power before installation, maintenance, or troubleshooting.
• Ensure the operating pressure and temperature are within the valve's specified limits.
• Use appropriate personal protective equipment (PPE) during installation and maintenance.
• Verify proper electrical grounding and wiring according to local codes and standards.
• Do not exceed the maximum operating pressure of 150 psi.

3. Installation

3.1 Mounting

• Mount the valve with the solenoid coil in the upright vertical position for optimal performance and life.
• Ensure sufficient clearance for maintenance and coil replacement.

3.2 Piping Connections

• Clean pipe threads and internal valve parts of any foreign matter.
• Apply pipe sealant sparingly to male pipe threads only to prevent material from entering the valve.
• Use a wrench on the valve body when making pipe connections to avoid twisting or damaging the valve.
• Ensure the flow direction matches the arrow on the valve body.

3.3 Electrical Connections

• Connect the valve to the specified voltage (120/60V, 110/50V).
• Ensure all electrical connections are secure and insulated to prevent short circuits.
• Follow all applicable electrical codes and standards.

4. Operation

The ASCO 8210G094-120/60,110/50 is a 2-way, Normally Closed (NC) solenoid valve. This means:

• When electrical power is not applied to the solenoid coil, the valve remains in its closed position, preventing fluid flow.
• When electrical power is applied to the solenoid coil, the coil energizes, opening the valve and allowing fluid to flow through.
• The valve will return to its closed position once power is removed.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your solenoid valve.

• Periodic Inspection: Regularly inspect the valve for any signs of leakage, corrosion, or damage to the coil or body.
• Cleaning: If the valve is exposed to dirty media, periodic cleaning of internal components may be necessary. Disassemble the valve carefully, clean parts with a suitable solvent, and reassemble with new gaskets if required.
• Coil Replacement: The solenoid coil is a wear item and may eventually fail. If the valve fails to operate electrically, the coil may need replacement. The coil is designed for easy replacement. Ensure the replacement coil matches the original specifications (voltage, frequency).
• Seal Replacement: Over time, the Nitrile Butylene seals may degrade. If internal or external leakage occurs, consider replacing the sealing components.

Always disconnect power and depressurize the system before performing any maintenance.
