  • Plastic diaphragm valve is a special type of cut-off valve. The biggest difference between the plastic diaphragm valve and other valves is that the structure without stuffing box is adopted; the rubber diaphragm can completely isolate the corrosive medium in the flow passage from all driving parts, thus eliminating the disadvantages of the common valve such as "running, emitting, dripping and leaking". The features of plastic diaphragm valve as follows (1) the soft rubber diaphragm valve can cut off the medium. (2) because rubber has certain corrosion resistance, it is generally used as corrosion-resistant materials to promote application, and continues to today. (3) the flow path is simple and has the function of "self-cleaning", which can be used for unclean media. (4) it is suitable for the transportation of corrosive medium, the regulation of closure and flow. The body touch medium use PVC, CPVC, PVDF , PP. It has excellent corrosion resistance, convenient operation, light volume and can replace stainless steel valves. (5) the seal diaphragm is made of PTFE or PFA, with fold resistance ≥ 1200 times, and corrosion resistance equivalent to F4. (6) adopt screw lifting structure, with large opening and closing torque and good stability.

  • Plastic check valve, also known as plastic one-way valve, is a kind of valve opened and closed by relying on the pressure of the medium itself, without manual switch. Plastic check valve is divided into swing check valve and ball core check valve according to the structure. The connection methods are flange type, wafer type, socket welding type, etc. The swing check valve uses the rotation of valve plate to open and close, which is suitable for horizontal installation. The ball core check valve uses the up and down movement of the ball core to open and close the valve, which is generally suitable for longitudinal installation. The plastic check valve is made of UPVC, CPVC, PVDF, PP, PPH materials which are not used according to the use conditions. The service temperature is generally 0 ℃ ~ 140 ℃, and the service pressure is generally less than 1.0MPa. Plastic check valve body is light in weight, compact and beautiful in structure, easy to install, strong in corrosion resistance, wear-resistant, easy to disassemble, easy to maintain and easy to operate, suitable for fluid: water, oil, corrosive chemical liquid. It is widely used in chemical industry, such as pure water and raw water pipeline system, drainage and sewage pipeline system, brine and sea water pipeline system, acid-base and chemical solution system.

  • The plastic ball valve adopts the ball core as the opening and closing parts, which is suitable for the corrosive medium. According to different materials, the service temperature is generally 0 ℃ ~ 140 ℃. Plastic ball valve parts are made of PVC, CPVC, PVDF, PP, PPH injection molded parts. The plastic ball valve use PTFE sealing parts and has excellent corrosion resistance . Flexible rotation and convenient use. The integral ball valve of plastic ball valve has few leakage points and high strength, and the connecting ball valve is easy to install and disassemble. Plastic ball valve has flange plastic ball valve, screw plastic ball valve, socket plastic ball valve, double plastic ball valve, etc. Plastic ball valve mainly has the following advantages. 1. Low fluid resistance.
