2.What's your MOQ?
A:1 piece is avaliable.

3.How can I get some samples? 
If you need, we are glad to offer you samples for free, but the new clients are expected to pay the courier cost, and the charge will be deducted from the payment for formal order.

4.  Can you make machining according to our drawing?
Yes, we can make machining according to your drawing, 2D drawing, or 3D cad model. If the 3D cad model can be supplied, the development of the tooling can be more efficient. But without 3D, based on 2D drawing we can still make the samples properly approved.

5.What's the delivery time?
A:Normally, 3-7 working days for sample. 12-30 working days for mass production.
  If any urgent parts, we can provide preferential processing and control the delivery time as you required.

We have spectrometer in house to monitor the chemical property, tensile test machine to control the mechanical property and UT Sonic as NDT checking method to control the process detect under the surface of machining.

7.How can I get the quotation?
A:Start a inquiry,send your 2D and 3D files,accurate and attractive prices will be sent quickly.
 

Wafer type check valves have Short face-to-face dimensions and low weight, and provide an economical, space-saving solution when compared to traditional swing check valves. 

Dual-plate Wafer Check Valve

Dual-plate check valves are are bonnetless and mounted between pipe flanges (wafer style). In this case, the valve includes two spring loaded half-moon shaped discs that rotate about their shaft. The actual designs of these valves vary between design models and manufacturers. Most have multiple flat seats. The dual-plate Check Valve disc has short rotational disc travel and responds quickly to flow stoppage or reversal, thus the potential for moderate water hammer does exist. It is somewhat better than the Swing Check Valve at minimizing potential water hammer, but with a much higher pressure drop.

Depending on the design, maintenance effort ranges from relatively simple to difficult. All dual-plate check valves must be removed from the line to perform maintenance due to the bonnetless design. The dual-plate check valve also results in a higher pressure drop when compared to a Tilting Disc Check Valve of the same size.

Single-plate wafer check valve

Single-plate wafer check valves(lift type) prevent reverse flow with disc movement that is parallel with the flow. With this design, the disc is always in the flow path. Discs are spring-loaded to assist in seating. 

And another thin type single-plate wafer check valves are swing type, that performs the same with swing check valve with much less cost. The disadvantage of this single-plate wafer check valves is, the inside diameters of the valves can only meet 60-80% of Norminal Pipe Size(NPS),  which limits the flow coefficient.
