Application, Dimension and specification of PZ673 Pneumatic Wafer Type Knife Gate Valve



PZ673 Pneumatic Wafer Type Knife Gate Valve is a relatively complex automatic control instrument, which is composed of a variety of pneumatic components and valve body. They are mostly used in applications that require fast cut-off or opening.

 

Pneumatic components


Pneumatic components include a pneumatic actuator and other pneumatic accessories.

1.   Pneumatic actuator

Double action: two-position control for valve opening and closing;

Single-acting spring return: When the circuit and air circuit are cut off or malfunction, the valve opens or closes automatically.

2. Single or double control solenoid valve (24V, 220V and other voltages are available for selection, if necessary, explosion-proof solenoid valve can be selected).

3. Limit switch.

4. FRL (including pressure reducing valve , filter, lubricator).

5. Electro-pneumatic valve positioner (for adjusting type).

 

Application 


By using accessories such as solenoid valve and limit switch, it can complete the action control and signal output of the two positions of open and close, and also can complete the automatic control of continuous action. The user can choose according to actual needs, for food, paper, medical drugs, oil and chemical oil, water, steam piping, connect or disconnect the line of fibers, dust, water treatment chemicals, sedimentation, Asphalt, silo outlet, fruit juice, grain and other media.
