DN15 Internal Thread Port 2W160-15 Pneumatic Water Diaphragm Valve For Wastewater Treatment

DN15 Internal Thread Port 2W160-15 Pneumatic Water Diaphragm Valve For Wastewater Treatment

The solenoid coil is another important factor affecting the low and high temperature of the 2W160-15 solenoid valve. When the coil size is not appropriate, the coil duty ratio can result in a failure of operation, especially when operating the valve at 100% duty ratio. It is similar to valve seals because of its ability to work in harsh conditions. Consider outside in addition to the pressure, flow rate and pressure drop, we also need to use the rated temperature of 180 ° C class H coil, copper wire can withstand high temperature but actually cannot exceed 180 ° C, in the design of the machine, coil temperature should be considered to avoid don't want to failure, such as solenoid valve performance degradation.

Features of DN15 Port 2W series solenoid water valves:

• Suitable for vacuum pressure
• Small size
• No pressure to open and act quickly
• Allow particle fragments to pass

Sealing materials of 2W water solenoid vaintroduction:

The mechanical, thermal and chemical conditions in the application are factors in the choice of sealing material. Standard materials for neutral fluids are at temperatures up to 194 °F, typically NBR. For higher temperatures, FKM and PTFE are involved. The following factors need to be considered when selecting the correct sealing material for the solenoid valve.

• Chemical compatibility
• Temperature of the medium
• Working pressure and burst pressure

PTFE 
PTFE stands for and is a well-known brand of Dupont . PTFE is resistant to almost all fluids, non-elastic (non-flexible), limiting its use in certain applications. It is mainly used for high temperature and high pressure solenoid valves, reaching a high temperature of 230 degrees Celsius. As a dynamic sealing material, it can be applied to all liquids, but especially the medium is gas leakage.

Benefits:
Its polymer contains chemistry for packaging electrical and corrosion resistant materials.
PTFE seals are commonly used in the following media: food industry, steam.
It has good wear resistance, wear resistance, most chemicals, load modification
Isolation diaphragms and body seals made of PTFE are highly resistant to corrosion.
The actuating portion of the solenoid valve and the body portion of the fluid flow are separated and the fluid used does not corrode the drive portion.

Disadvantages:
PTFE particles, dust, and impurities are more fragile, and the use of fluids containing the above media can affect the flow passages installed in the filter unit to prevent foreign matter from entering.
PTFE (polytetrafluoroethylene) is poorly resistant to hydrofluoric acid and hot caustic solutions.
