  ZECO wafer check valve is simple in design because the wafer connection is named and consists of body, disc, spring and shaft pin components. Due to the short closing stroke of the wafer check valve and the quick closing by the spring, the impact on the water hammer can be significantly reduced. The wafer check valve can also be divided into wafer type lifting check valve, wafer type dual plate check valve and wafer type single plate check valve.

  Wafer Dual Plate Check Valve
  The structure of ZECO wafer dual plate check valve is that the disc is along with the pin at the center position of the body to swing, short structure dimensions, small volume.
  Wafer Type Nrv
  Wafer type NRV has a shorter face-to-face dimension and dual plate design, the end connection options include wafer type, lug type and double-flange type, and are available in size from 2" to 60" and in pressure ratings from ASME class 150 through 2500.

  When ZECO helps users to choose the wafer check valve for pipelines, it will give the corresponding scheme. The wafer check valve is usually installed in the pipeline that may produce a water hammer. Because of its structural characteristics, the wafer check valve can effectively eliminate the water hammer generated by the counterflow of medium. Another feature of the wafer check valve is that it does not need flange connection, saving installation space. It only needs to be installed in the middle of two pipe flanges, and then fixed with bolts. 
  ZECO is specialized in the wafer check valve manufacturers and carries on the design and production strictly in accordance with API 594 standard, the size range of products made from 1/2 "to 88", nominal pressure from 150 lb to 2500 lb. Main valve material includes carbon steel, low-temperature steel, dual-phase steel, titanium alloy, aluminum bronze, Inconel, Monel alloy and other metal materials, products widely used in oil and gas, in the field of global energy, chemical and other industries.

  ZECO is a professional manufacturer of swing check valves. Swing check valves are API 6D products. Check Valve is automatically prevented fluid backflow valve, disc of the check valve is opened by fluid force, then fluid flows from the import side to export side. When the import side pressure is lower than the export side, the disc will automatic closed to prevent fluid backflow in the factor of the fluid pressure and gravity itself.

  Stainless Steel Swing Check Valve
  ZECO is a professional manufacturer of swing check valves, stainless steel materials can be selected ASTM A351 CF8, ASTM A351 CF8M, ASTM A351 CF3, ASTM A351 CF3M, UNS S32205.
  High Temperature Check Valve
  The seat of ZECO high-temperature check valve is designed renewable. When the seat needs to be replaced over time, do not remove the entire valve, just remove the bonnet and replace the seat.
  Introduction of Swing Check Valve
  The role of the Check valve is only allowing the medium to flow one direction, and that to preventing the flow direction. Usually, the type of this check valve is automatic, under a direction of flow of fluid pressure, the disc is opened; When fluid is flowing in the opposite direction, fluid pressure and the disc act on the seat, thereby cutting off the flow. The primary function of the check valve is to prevent the backflow of the medium pipe, so check valve is often selected in the export and extraction pump, exhaust pipes, such as the export side. Characterized by the pipeline flows in the medium itself and the forces generated by the automatic opening and closing. 
  ZECO swing check valve uses arm disc as swing structure, arm and pin shaft are installed inside the body, with few leakage points, eliminating the possibility of external leakage caused by structural problems. The ZECO 900 and 1500 lb swing check valves can also be bolted to the body and bonnet to ensure that the bonnet can be removed for replacement in the event of damage to the middle ring or to the interior for easier maintenance and repair operations. ZECO swing check valve has been widely used in many fields such as oil, gas, refining, industry and so on.

  LOOK AT WHERE SAPPHIRE WAFER APPLIED
  1. Semiconductor LED industry (MOCVD epitaxial GaN substrate)
  
  In general, C-plane sapphire is needed in this area. R-plane or M-plane mainly used to grow non-polar/semi-polar plane epitaxial layers to improve the luminescence efficiency.
  
  2. The growth of III-V or II-VI compound semiconductor.
  
  3. Microelectronic IC applications especially Very High-Speed Integrated Circuit, SOS
  
  Generally, it is a silicon heteroepitaxial deposition on R-plane sapphire.
  
  4. Hybrid microelectronics
  
  Hybrid microelectronics products are mainly HIC and MCM. It has high requirements on the substrate, while sapphire's characteristics such as stable dielectric constant and low dielectric loss make sapphire wafer the most commonly used substrate for HIC and the main substrate for MCM. Generally, the A-plane sapphire wafer is needed.
  
  
  SAPPHIRE WAFER PROCESSING
  At the very beginning, we have a crystal boule.
  
  Crystal growing: Produce high-quality sapphire monocrystals via furnace.
  
  Sapphire ingot processing: Drill out the ingot, Ground the ingot, Quality inspection.
  
  Then we get the sapphire ingot.
  
  Orientation: Position the ingot on the sawing machine.
  
  Sawing: Cut the ingot into thin wafers.
  
  Lapping: Lap the wafer to remove the scratched layer and improve its flatness.
  
  Chamfer: Trim the edge of the wafer into an arc to improve the mechanical strength, to avoiding stress concentration.
  
  Polishing: Reduce the surface roughness to reach the epitaxial wafer grade.
  
  Cleaning: Remove dirt from the wafer surface.
  
  Quality inspection: Inspect wafer with a high precision instrument to meet customer's requests.
  
  Finally, we get the sapphire wafer.  less
