ZCQ-01B-66 Electric Solenoid Valves

ZCQ-01B-66

Electric Solenoid Valves

Instruction&Advantage

1.Varies types of solenoid valves (With diaphragms/With pistons/Two-way Bi-flow valves).

2.can be widely used in refrigeration, pneumatic and hydraulic system, also in boiler and fire-fighting, etc.

3.good insulation, waterproof, moisture proof, anti-vibration and corrosion resistance.

4.use full closed magnetic coil and DIN international standard electric plug.

5.Certificates: ISO, CQC, CE, DNV etc.

Operating principle

1.When the coil is energized, the electromagnetic power opens the small orifice.

2.Then the pressure in upside of valve will reduce, the pressure difference between both side of diaphragm happens.

3.and make diaphragm lift to open the main orifice.

4.When the coil is de-energized,the plug stem will drop and close the small orifice because of spring force and its weight.

5.The medium enters into upside of diaphragm through throttle hole.

6.then the pressure in both side of diaphragm will downside.

7.Finally  the diaphragm will drop and close the main orifice.

Usage

1.The valve must install in horizontal pipe line under vertical position. The flow direction must meet the arrow direction in valve body.

2.The oil input voltage must meet rated input voltage showed on the label. Departure coil from valve when energized in coil is not

permitted in order to avoid damage the coil.

3.According to valve with manual function, it must turn manual bar to open the valve before doing system air tightness in order to

avoid to damage diaphragm.

4.When brazing the valve with connect tube in system, follow points are very important:

a.Before brazing, coil must be departure and use wet fabric cover the valve body to avoid to damage valve part because of high

temperature when brazing.

b.It must avoid the brazing flame face to valve body.

c.It is better to adopt low temperature type silver brazing bar.

5.According to valve with manual function. The manual bar must be turned to open the valve before doing system air tightness, in

order to avoid to damage the diaphragm.

6.Coil must be set to the body when the current on.
