Commodity Details:

 Product description: the constant electromagnetic valve FDF8MB 220 v screw

 Unit: only

 Model: FDF8MB

 Sales instructions: phi 10 (over) 1.0 (traffic)

Products characteristics:

1.Provides a normally closed (NC) and normally open (NO)

2.There are a number of ac voltage and dc voltage coil for choice

3. The solenoid valve flange installation type are available

4. Good waterproof, moisture proof, seismic and acid and alkali

Product Usage:

FDF solenoid valve is suitable for the freon refrigerant, water, liquid, gas as working medium,using electrical signals to the remote control line in the working medium,To realize the automatic on-off and achieved the integration of mechanical and electrical.FDF solenoid valve opening valve rapidly, stable performance, easy to use, energy saving, long life, etc.

Product Use:

This series solenoid valve can be widely used in refrigeration, pneumatic, hydraulic system, can be suitable for cold storage, refrigeration, air conditioning device, suitable for as, HFC refrigerants and compatible lubricants (except R717)

Working Principle:

FDF solenoid valve series for indirect normally closed electromagnetic valve (i.e., secondary open valve).Including FDF3 is straight moving type structure.After the coil current, magnetic field, magnetic, suck up the iron core, small piston valve is opened mouth, make the upper piston pressure unloading, under the action of pressure difference, push on the piston, the main valve opens the mouth to form pathways.Cut off the power and core loss of magnetic force and under the action of the spring automatic reset and falling, close the small piston valve mouth, put pressure on the piston speed, prompted the piston down, cut off the line, in a close to normal.

Technical Parameters:

Applicable temperature: 25 ℃ ~ 105 ℃

Connection: thread the SAE

Connection: thread the SAE

The Instructions on Solenoid Valve:

1. The solenoid valve must be installed in horizontal pipe runs vertically, the medium flow direction should be the direction of arrow and the solenoid valve is shown in.

2. The work coil input voltage must be consistent with the rated voltage marked on the coil.Must not be allowed in the electromagnetic coil electricity when removed from the valve, in case burn out the coil.

3. Electromagnetic valve welded pipe with pipe welding system, must pay attention to the following points:

   A. to be removed from the valve solenoid coil, with a damp cloth or wet cotton yarn package in the body to protect the body, to prevent the welding temperature burn out parts in the valve.

   B. please note when welding torch flame direction

   C. had better choose high silver electrode welding

   D. the electromagnetic valve with the manual lever, must first rotating pole make the valve opened manually, and then do system tightness test, so as not to damage the diaphragm

The Quality Assurance Period:

Products will be backdated to manufacture date 18 months from accessories fee and artificial cost, 24 months free labor
