1.ppr elbow is a pipe fitting that changes the direction of the pipeline

2. ppr union and pipe sleeve are used for the connection between ppr pipe and metal pipe

3. The ppr tee and spool are used to change the direction of the fluid

4. The ppr cap and plug are used to seal the reserved tube

5. The holding card, high card and low card of Ppr pipe fittings are used to fix the pipeline, and the ppr ingot bay and bend are used for the bypass connection of the cross-arranged pipeline

6. Ball valve: its main features are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are always in a closed state, which is not easy to be eroded by the medium, and is easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries.

7. The opening and closing parts of the globe valve are plug-shaped discs, the sealing surface is flat or conical, and the discs move linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem rises and falls, and the handwheel does not rise and fall), and there is also a lifting rotating rod type (the handwheel rotates and lifts together with the valve rod, and the nut is arranged on the valve body).

The globe valve is only suitable for fully open and fully closed, no adjustment and throttling are allowed.

8. Y-type filter is an indispensable filter device for the pipeline system conveying medium. Y-type filter is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to remove the medium. impurities to protect the normal use of valves and equipment.

9. The valve magnetic lock relies on the force of the magnetic force to control the opening and closing of the closing member in the valve. No gap, anti-clogging, waterproof, anti-corrosion, easy to use; favored by water supply, heating, gas, solar water heater and other industries.

10. The quick-open ball valve is evolved from the plug valve. Its opening and closing part is a sphere, and the sphere is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing.

The ball valve is mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with V-shaped opening also has a good flow adjustment function.
