UPVC
PVC is formed by the polymerization of vinyl chloride monomer (VCM). When PVC is mixed with solid additives, the resulting product is called PVC, also known as rigid PVC. It has strong mechanical properties, wear resistance, flame retardancy, good dielectric properties, and excellent corrosion resistance, making it suitable for general corrosive fluids.
CPVC
CPVC is a high molecular material with higher chlorine content, produced by chlorinating PVC molecules again. Its average chlorine content reaches 74%. Due to the increased chlorine content, it demonstrates significantly better temperature resistance, acid/alkali resistance, and mechanical strength compared to UPVC. Additionally, it features a higher ignition point, low smoke emission, lower electrical conductivity, and superior wear resistance. These characteristics make it the optimal material for industrial pipe fittings and valves.
PTFE(polytetrafluoroethylene)
Polytetrafluoroethylene (PTFE), commonly known as "Plastic King", is a polymer compound formed through the polymerization of tetrafluoroethylene. It exhibits excellent chemical stability, corrosion resistance, sealing properties, high lubricity and non-stick characteristics, electrical insulation, and outstanding aging resistance. PTFE remains virtually unaffected by most chemical reagents. For instance, it maintains its weight and performance even when boiled in concentrated sulfuric acid (98%), nitric acid, hydrochloric acid, or even boiling water, while being insoluble in nearly all solvents.

Q: Could you offer the free samples ?
A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055
Q: What ' s your business scope ?
A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .
Q: What types of products you can make ?
A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .
Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible .
Q:Can you provide original famous pneumatic and hydraulic,instruments brand goods ?
A: Yes,We can supply like Festo,Smc,Ckd,Burket,Hydac,Rexroth,Siemens,Rosemount,Marsh ,Endress+Hauser etc.
Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
