ચેતવણી: આ ઉત્પાદન તમને સીસા સહિતના રસાયણોના સંપર્કમાં લાવી શકે છે, જે કેલિફોર્નિયા રાજ્યમાં કેન્સર અને જન્મજાત ખામીઓ અથવા અન્ય પ્રજનન નુકસાનનું કારણ બને છે તે જાણીતું છે. વધુ માહિતી માટે અહીં જાઓ www.P65Warnings.ca.gov.
- Always disconnect power before installing, servicing, or performing maintenance on the valve.
- Ensure the valve is compatible with the fluid or gas being controlled. The VITON gasket is suitable for gasoline, kerosene, and other organic solvents. Do NOT use NBR gaskets for gasoline.
- Install the valve in a location that is easily accessible for inspection and maintenance.
- Ensure proper electrical connections are made according to local codes and regulations.
- Avoid exceeding the maximum pressure and temperature ratings specified for the valve.
3. ઉત્પાદન સુવિધાઓ
- 1/2" NPT (USA National Pipe Thread): Commonly used standard pipe thread in the U.S.
- સોલિડ બ્રાસ બાંધકામ: The valve's body is made of solid brass, offering excellent corrosion resistance.
- Unidirectional Flow: An arrow on the valve body indicates the intended flow direction. Horizontal mounting is recommended.
- Direct Acting and Normally Closed: The solenoid's magnetic field directly moves the plunger to close the orifice for fluid or gas flow. The valve only opens when energized.
- VITON Gasket: Viton is a chemically inert material, ideal for use with gasoline, kerosene, and other organic solvents.
- IP65 રેટેડ: Provides protection against dust ingress and low-pressure water jets from any direction.

4.1 યાંત્રિક સ્થાપન
- Identify the inlet and outlet ports. The valve is unidirectional, and an arrow on the body indicates the flow direction.
- Apply appropriate thread sealant (e.g., PTFE tape) to the 1/2" NPT threads before connecting to piping.
- Mount the valve horizontally for optimal performance.

4.2 વિદ્યુત જોડાણ
The valve operates on 12V DC. Connect the power supply to the solenoid coil terminals. The polarity for DC operation typically does not matter for the coil itself, but ensure your power supply is correctly wired.
- Connect the positive (+) lead from your 12V DC power source to one terminal of the solenoid coil.
- Connect the negative (-) lead (ground) from your 12V DC power source to the other terminal of the solenoid coil.
- શોર્ટ સર્કિટ અટકાવવા માટે ખાતરી કરો કે બધા વિદ્યુત જોડાણો સુરક્ષિત અને ઇન્સ્યુલેટેડ છે.
5. ઓપરેટિંગ સૂચનાઓ
This is a normally closed (NC) solenoid valve. This means that when no power is applied to the coil, the valve remains in a closed position, preventing fluid or gas flow. When 12V DC power is applied to the coil, the solenoid energizes, pulling the plunger and opening the valve to allow flow.
- To open the valve: Apply 12V DC power to the solenoid coil.
- To close the valve: Remove 12V DC power from the solenoid coil.
- The valve is designed for short cycles. For applications requiring continuous flow for extended periods (e.g., over 3 hours), consider using a motorized valve instead.
6. જાળવણી
Regular inspection and maintenance can extend the lifespan of your solenoid valve.
- સફાઈ: Periodically inspect the valve for debris or buildup, especially if used with fluids containing particulates. The valve features a removable plug for easy internal maintenance and cleaning.
- ગાસ્કેટ નિરીક્ષણ: Check the VITON gasket for signs of wear, cracking, or chemical degradation. Replace if necessary to prevent leaks.
- કોઇલ નિરીક્ષણ: Ensure the solenoid coil is free from physical damage or excessive heat buildup.
- લીક તપાસ: Regularly check all connections for leaks.
