ZLF type (ZL - 4 m) series for flow control valve (self balancing valve) is a kind of intuitive easy flow adjusting control device, the network application of the valve can be directly set according to the design flow, the valve can be used in water, automatic eliminate the remainder of the pipeline pressure head and flow caused by pressure fluctuation is poor, no matter what the system pressure change all the set flow rate unchanged, the valve is finished at one time, these features make the network flow control to the net work for simple flow distribution, effectively solving the hydraulic imbalance between the network.

Q:Pressure gauges, safety valves and other safety accessories and the cylinder can be installed between other valve components,
The lower part of the pressure gauge installed water pipe, there are water, avoid high temperature, medium pressure gauge contact directly cause damage, so regular cleaning, in order to avoid congestion, three way plug function is used for flushing, please see "how to operate them.".
Q:How about leaking water pipe valve?
It depends on where the place is leaking.1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
Q:How does the valve open?
Now the valve is in a closed state, the general valve on the valve flow direction marked, like you figure on this, flat side perpendicular to the flow channel is closed, parallel to the flow channel is open.
Q:What's the caliber of the valve 1/4?
1 inches, =25.4 millimeters, 1/4 inches, =2/8 inches, =2 minutes, =DN8 (mm)3/8 inches =3 points =DN10 (mm)1/2 inches, =4/8 inches, =4 minutes, =DN15 (mm)3/4 inches, =6/8 inches, =6 minutes, =DN20 (mm)1 inches =DN25 (mm)1 1/4 inch =DN32 (mm)1 1/2 inch =DN40 (mm)2 inches =DN50 (mm)
Q:What's the sewage treatment valve with?
Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective. Butterfly valve manufacturers are many, the price is also different, as long as the right can.
Q:Symbols for all types of valves
Look at the attachment I gave you. The legend of the valves is complete!
Q:What does the 4 point valve mean?
That is not clear, American Standard or GB, or what other
Q:How to quickly identify the types of valves?
You can look through shapes, signs, or buy a valve manual
Q:How can the valve actuators be classified?
84798990 straight stroke valve actuator84798990 angle stroke valve actuator84798990.90 all intelligent electric valve actuator84818010 valve actuator84819010 valve actuator85371090 electric valve actuatorFor the past 3 years, the shipment code, but not the same as yours, for reference
Q:What does the "XV" valve mean?
XV if in front of the valve position, such as XV2211-011, then the XV indicates the switch valve, which is a representation of the Control Valve relative to the regulating valve.
