Wafer check valves – how do they work, and what are their types, features, & benefits? Valves are critical in almost all industrial projects, from construction to HVAC and aerospace to automobiles. Though valves have existed since the Roman period, they have become indispensable in various industrial verticals in the past few centuries. These are essential in making many projects successful as they control the gas or fluid flow per specific requirements.
The experienced manufacturer makes many forms of valves in different shapes, sizes, etc., using various high-quality materials to be flexible and durable. The best among them is the wafer type check valves, which are helpful in many industries like oil & gas, mining, power generation, etc. This is because wafertype check valves are slim without gaskets to fit between flanges and are ideal for limited-space applications.
In this article, let us discuss dual place check valves, aka wafer check valves, and how they work along with their many types and features to buy the right one per customers' specific needs and budget to make their projects cost-effective and successful.
What is a wafer-type check valve?
In most piping systems, domes, tic water plumbing systems, industrial oil & gas, or chemical industries, any reverse flow can use many undesirable occurrences. It may be because of lower upstream than downstream that such reverse flow causes even huge damages. Many domestic workers must ensure buildings have proper plumbing, heating, ventilation, air conditioning, etc. For industrial applications, for one direction flow of chemicals, oil & gas, and others, any reverse flow will cause a massive loss of property and precious life.
Here, the wafer check valves play a critical role; the best among them are type check valves, also known as one-way, reflux or non-return valves. Many significant reasons for it include the slim design, which fits in tight places and is helpful in applications in many sectors. Some industries include food & beverage, pharmaceutical, supply, chemical, mining, steam power generation plants, and oil & gas.
How does the wafer check valve work?
Compared to other check valves, dual plate check valves are far better at ensuring single directional flow of fluid or gas to be useful in many industries. This is because of its vast difference in functionality, as it takes less space and does not have gaskets that do not have enough space for the disc to open in the pipeline. However, dual plate check valves are slim and without gaskets to enable the complete opening of the valve for free flow of the fluid.
The moulded body around the disk area of the wafer checks valves to provide enough space for the disc to swing open freely. Also, the top manufacturer makes wafer type check valves with two springs loaded on a central hinge plan and designed according to the API 594, 598 and 6D to confirm all the stringent testing requirements.
What are the features, types and benefits of dual plate check valves?
There are many fantastic features of wafer check valves, like two spring-loaded discs or plates held together by a hinge mechanism. These plates will open only when the fluid flows in the forward direction, and if, for pressure or other reasons, it flows backward, the discs close to avoid it; also, compared to other valves, wafer-type check valves are easy to install, maintain and operate safely.
There are many types of dual plate check valves, such as reduced-flow, non-slam, retainer-less, and others, for specific uses. Also, the wafer-type check valves have many benefits by being a critical part of many vital industries like oil & gas, HVAC, fire protection, water treatment, and others.
Advance Valves, one of the top three valve manufacturers in India, makes high-quality wafer check valves at competitive costs in its over 280,000 sq ft state of manufacturing unit and offices in many continents.
