Plastic Valve Types
Plastic Valves falls into two different categories: manual and actuated. Both types have their own subgroups.
Manual Plastic Valves
Manual plastic valves, manually controlled. Due to their simple operation, easily opened and closed, relatively convenient for manually controlled applications rather than other types.
Manual Plastic Valve Types
- 2-way ball valve
- 3-way ball valve
- The butterfly valve
- Diaphragm valve
- Check valve
- Pressure control valve
- Auxiliary valve
Plastic Valves with Actuators
Actuated plastic valves open and close upon the operating system. Since manual operation of large-sized valves are difficult, actuating versions generally preferred. In addition, actuating plastic valves used in systems where the valve needs to be opened and closed quickly.
Actuated Plastic Valve Types
- Ball valve
- The butterfly valve
- Diaphragm valve
- Solenoid valve
Plastic Valve Materials
Plastic valves, which offer ease of use with their easy opening and closing system, light weight and small footprint, produced out of different types of plastics.
Plastic Valve Material Types
Each type of plastic listed above has its own characteristics. For example, PVC-U is resistant to temperatures between 0-60°C, while PVC-C can be used up to 90°C. Or, while PVDF is resistant to acidic fluids, contrary with low resistance to basic fluids above 11 pH. On the other hand, PP-H is resistant to organic solvents, degreasers and generally corrosive environments. What so ever type of plastic valves to be chosen upon fluid type & its pH value, respectively the corrosiveness and operating temperature to be taken into consideration.
