The valve core and valve seat of Runjing ceramic hard sealing ball valve are made of corundum ceramic or silicon carbide, the Rockwell hardness HRA can reach 85 or more, and the roundness of the ball core is less than 6μm, it rotates relative to the almost completely fitted valve seat to realize light torque opening and closing. It has completely changed the shortcomings of traditional plastic ball valves and metal core ball valves, which are easy to leak, high torque and poor corrosion resistance sealing surfaces. Runjing ceramic ball valve could solve various problems that traditional ball valve can’t solve, it has wide range of applications, the application of ball valve in water treatment system is a more common one.

Ammonia nitrogen removal facility in Shijiazhuang, Hebei

Customer Requirement: using 3-5% concentration sulfuric acid and lye to regenerate, the ball valve is required to be corrosion resistant.

Solution: adopting 20 sets of Runjing DN25 ball valve, which have steady chemical properties and good acid and alkali corrosion resistance.

Sewage treatment and reclaimed water reuse equipment for a company in Wenzhou, Zhejiang

Customer Requirement: the ball valve is required to be corrosion resistant, anti-scaling and wear resistant.
Solution: adopting several sets of Runjing ball valve, the valve core is free of scale, good corrosion resistant and good wear resistant.

Seawater desalination equipment of a company is Taizhou, Zhejiang

Customer Requirement: the high salt content of sea water requires the ball valve to have good corrosion resistance and high waterproof level.

Solution: adopting several sets of Runjing ball valve, which have high temperature resistance, good corrosion resistance and salt spray resistance.

The characteristic of low torque of Runijng ball valve, making it’s size of actuator is only 20-30% of that of other ball valve products under the same specification, which greatly reduce the volume of actuator and save the installation space. And then greatly reduce the cost of production and improve the equipment cost performance.

Medical water equipment of a company in Changsha, Hunan

Customer Requirement: the installation space is relatively narrow, requiring small actuators, low power, safe and stable operation.
Solution: adopting 11 sets of Runjing DN20 ball valve, which are equipped with low torque, small actuator and easy installation in narrow space.

Corundum ceramic or silicon carbide are sintered under 1680℃ or 2200℃ ultra-high temperature, so it has good high temperature resistance, and can be used for various equipment that need to operate under high temperature.

Hot disinfection water treatment of a pharmaceutical factory in Shenyang, Liaoning

Customer Requirement: water temperature is 100℃, requiring the ball valve has stable temperature resistance.
Solution: adopting 10 sets of Runijng stainless steel ball valve, which are equipped with corrosion resistance, wear resistance and can operate steadily under the high temperature.

In large flow rate system, the filtration and softening system composed of Runjing ball valve is suitable for a wider range of water supply pressure, a wider range of flow options, more stable equipment operation and longer service life.

Water softening equipment of Peking University Health Center

Customer Requirement: backwash flow rate is large and has steady operation.

Solution: adopting F109 ball valve control system (several DN50 and DN40 Runjing ball valve with F109), which is more impurity resistant and more durable.
