Kinvalve Spring Check Valve Guard Your Valuable Downstream Components
Kinvalve spring check valve, also known as spring load check valve or spring assisted check valve, is an iteration of the swing check valve.
Kinvalve spring check valve acts in the same function as the swing check valve, but it has a spring to stay close when there is no flowing through. This means the Kinvavle spring check valve can offer you a much shorter shutoff time than the swing check valve.
Quick shutoff action will help minimize the effects of water hammer especially when your application features frequent backflow.
Kinvalve spring check valves have spring assisted closing plates designed to ensure that they close before return flow occurs. You can use them for water/sewage systems, pneumatic, hydraulic or gas applications.
In any of your applications where backflow will damage or cause contamination, Kinvalve spring loaded check valves are an easy and reliable solution.
As an inspired spring check valve manufacturer, Kinvalve can customize your spring check valves in a wide variety of connection types, cracking pressures, and seat materials in accordance with the specifics.

Kinvalve: Your Trusted Spring Loaded Check Valve Manufacturer
At Kinvalve, depending on whether the valve plate has an auxiliary spring, you can divide the check valve into two categories. Featuring a spring-loaded disc for a check valve means pretty more than what you think.
Our no spring check valve is a swing check valve, including a traditional swing check valve in T pattern and a thin wafer swing check valve with a single plate. Kinvalve can supply many types of spring load check valves including inline spring check valves and dual plate wafer check valves.
Inline spring check valve
Kinvalve inline spring check valve is a kind of inline check valve with a straight flow direction. This kind of inline check valve features the disc held in the axial place by a spring.
This axial movement of the disc allows for smoother fluid flowing and responsive opening and closing. And this characteristic also prevents the sudden movements that cause water hammer to damage your equipment or pipelines.
At Kinvalve, there are two types of the inline spring check valve, disco check valve and threaded type inline check valve. Our threaded type inline check valves feature simple construction and cost-efficient solution.
Kinvalve threaded inline spring check valves are usually small check valves, with sizes range up to 4inches, and they are widely used for your low-pressure applications.
At Kinvalve, threaded inline spring check valves are also known as vertical check valves. This vertical check valve is available in 2-piece body and 3-piece body.
The 2-piece vertical check valve features simple construction with a less leaking path. And the 3 piece vertical check valve features a swing-off body design for easy maintenance when it is still inline.
Kinvalve vertical check valves are usually small check valves with sizes ranging from 1/4inch to 2inches. At Kinvalve, a vertical check valve can be installed in any position like vertical and horizontal in your pipelines.
For disco check valves, this kind of spring-loaded check valve is designed to be a compact wafer body with short disc traveling. This type of spring-loaded check valve also provides quick closing with less water hammer pressure in your pipeline.
Kinvalve disco check valves are large check valves, available in many sizes. Kinvalve disco check valves are typically from 2” to 12” in ASME pressure class 125 through 300 and API 6A&6D pressure classes. DIN, JIS and BS standards are also available for your options.
At Kinvalve, the disco check valve features spring-assisted, non-slam, axial flow, and silent operation. This type of spring check valve is a typical axial flow check valve.
Kinvalve axial flow check valves are designed with fast closure in mind. These spring-loaded discs in these check valves go from fully open to fully close with a significantly short travel distance than other types of check valves.
Actually, Kinvalve axial flow check valves are recommended to safeguard your pumps and compressors and other equipment.
Water hammer poses a risk in most pipelines and processing systems in your applications. Without proper solutions in place to mitigate hydraulic shock, your systems are at risk of burst, leaking, or excess long-term erosion.
This above all makes it especially important to use axial flow check valves that can act as quickly as possible to prevent reverse flow without creating a damaging hydraulic pressure wave which can wear your pipeline or destroy the joints and equipment.
Dual plate check valve
Kinvalve dual plate check valve features wafer type body, spring-loaded double-disc, and non-return characteristics. This type of dual plate check valve is also known as a dual plate wafer check valve or duo check valve.
Kinvalve dual plate check valve offers the relative cracking pressure to provide the low-pressure drop in your system, and we also can customize the cracking pressure by adjusting the assisted spring to follow your specifications.
As a dual plate check valve manufacturer with over 18-year experience, Kinvalve can customize your dual plate wafer check valve in accordance with ANSI/API, DIN or JIS standard.
At Kinvalve, stainless steel spring check valves are the commonest check valves that feature whole stainless steel construction.
Our stainless steel spring check valves are suitable to widely used in conjunction with several system fluids and are also capable of handling a number of different temperature and pressure combinations for your specific requirements.
As one of the superior spring check valve manufacturers, Kinvalve knows everything about the spring check valves, knows the pros and cons in detail.
We have been committed to improving the inherent shortcomings of various check valves so that they can better serve you in specifications.
