Kinvalve Wafer Check Valve Delight Your Customer
As the name indicates, the wafer check valve is has a compact wafer design. This wafer check valve is fitted to your flange pipelines, between two flanges in accordance variety of standards.
When your application has water hammer, space limitation, or flow requirements, the wafer type check valve is your best choice.
The wafer check valve has the advantages of the traditional swing check valve and avoids its disadvantages. You can consider our wafer swing check valve as an evolution of the conventional swing check valve.
Compared to the traditional swing check valve, the disc travel of the Kinvalve wafer check valve is short with less impact and the disc closes quickly to cause less water hammer pressure.
And it requires less cracking pressure. Kinvalve wafer check valves are more reliable than traditional swing check valves due to these advantages above.
In addition, this compact thin design provides a much less weight increase to your pipeline load. They are intended to be light in weight, robust and less expensive.
You can customize the soft seal for your wafer check valve to meet your requirements for drip tight. But more often, our wafer check valves have integral or welded metal seats.

Kinvalve Your Expert of Wafer Check Valve Supplier
At Kinvalve, there are many types of wafer check valves for your choice. They are butterfly check valves, as well as a disco check valves and wafer swing check valves.
As one of the best wafer check valve manufacturers and suppliers, Kinvalve can customize your wafer check valve in various body materials, constructions, seating arrangements to satisfy the specifications.
Butterfly Check Valve
Kinvalve butterfly check valves, as the name implies, when it’s on and off, the two separate valve plates look very like the wings of a butterfly. This kind of wafer spring check valve is also known as DUAL PLATE CHECK VALVE.
For a kinvalve typical butterfly check valve, the medium flows through the valve when the flow pressure is greater than the cracking pressure.
When the flow in your pipeline stops or decreases, and the flow pressure is smaller than the shutdown pressure, the two butterfly plates are forced to close the valve, preventing the medium from backflow in your system.
As one of the best butterfly check valve manufacturers, Kinvalve can customize your butterfly check valves in either a body-welded wear-resistant metal sealing surface or a soft lining rubber-sealing surface.
Kinvalve also can offer adjustable springs to satisfy the specific cracking pressure requirement in your applications.
Although Kinvalve butterfly check valves are excel in good design and perfect construction to eliminate backflow and water hammer in your pipelines, you still need to make the right decision when to decide on a butterfly check valve for valuable components.
Kinvalve butterfly check valves are available in wafer design, flanged design, and lug type design to match your specific pipeline joint demands.
These three types of butterfly check valves are known as dual plate wafer check valves, DUAL PLATE LUG TYPE CHECK VALVE, and DOUBLE FLANGED DUAL PLATE CHECK VALVE.
At Kinvalve, not only the butterfly check valves but also all the spring check valves are available in the flexible installation.
You can install them in horizontal or vertical pipes. In the vertical installation, you don’t need to consider its direction, upward or downward.
As an expert butterfly check valve manufacturer, Kinvalve devotes itself to serve you every significant application with our customizable butterfly check valves.
Disco Check Valve
Kinvalve disco check valve is also named as wafer disc check valve. Kinvalve disco check valve features spring-loaded disc and relatively short in wafer design.
The spring-assisted disc automatically shutoff the flow when the pressure drop during a range, which prevents the flow reversal and water hammer in your pipelines silently and non-slam.
Kinvalve disco check valves are relatively short in design and provide a low cracking pressure. If you want to consider both silent operation and cost, then this kind of spring loaded wafer check valve is the preferred choice.
You can get the benefits of eliminating water hammer and backflow shocks from its unique design of short linear stroke and spring-assisted closure.
Kinvalve wafer disc check valves are designed with a single, central-guide and spring loaded disc, which is fully guided by the central stem at the bottom to prevent binding and cocking.
Our disco check valves are considered the improved performance of a butterfly check valve.
In the case of the disco check valve, the trim moves parallel to the axis of the flow path with the opening or closing of the central guided disc.
At Kinvalve, disco check valve is mounted with two types of sealing surfaces including metal seal and soft seal. The metal sealing surface is equipped with a kind of high temperature check valve and recommended to be used for steam applications.
And the soft seal is usually NBR or PTFE, which can provide reliable drip tight for your zero leaking requests.
As a wafer check valve manufacturer and supplier, Kinvalve wafer disc check valves are available in API/ANSI, DIN, and JIS standard design, with the pressure ratings of Class 150/300 or PN10 to PN40.
Kinvalve devoted in providing wafer check valves to meet your requirements. In some cases, we can also customize the check valve according to your requirements, and even provide you with a one-stop solution.
That’s why Kinvalve has been trusted by our customers like you from all over the world and established long-term cooperation with them.
Wafer Swing Check Valve
At Kinvalve, the wafer swing check valve is also named as a single plate check valve, single-plate wafer check valve, single disc swing check valve, or single disc wafer check valve. Kinvalve wafer swing check valve is a kind of single plate check valve.
Kinvalve single plate wafer check valve features a compact, lightweight body, single disc construction and a low head loss. Our wafer swing check valves are available in metal or soft seating arrangements.
At Kinvalve, we can offer this single plate swing check valve in both stainless steel and carbon steel body. The seating arrangements of this wafer swing check valve are stainless steel and elastomers like NBR, EPDM, VITON or PTFE.
As a professional wafer swing check valve manufacturer, Kinvalve can customize your single plate wafer check valve in spring or springless return, with the flanges according to ANSI or DIN standard. And we offer optional material and pressure rating of the spring as your specific requirements.
Kinvalve wafer swing check valve, thin type using a swing disc to allow or block flow. This design allows them to be fitted in extremely tight space, where other flanged or wafer check valves can not be used.
And due to the thin type body, the swing disc can’t be contained within the body but swing to the pipeline, so the wafer swing check valve is usually designed as a reduced bore check valve with a relatively smaller disc for fully open in the pipeline.
As you can imagine, our thin type wafer swing check valve is usually used for applications where the flow is not an issue, and a traditional swing check valve or other type wafer check valve is recommended when the full port check valve is required in your systems.
As a leading wafer check valve manufacturer, Kinvalve knows everything more than you need to think before purchasing.
Whether you want a butterfly check valve, wafer silent check valve, wafer lug check valve, as well as a wafer spring check valve or wafer swing check valve, our engineers will help you.
