When you are installing a custom Check Valve in a system, there are some things to keep in mind. Check valves should never be installed vertically, and should be situated at least 5 pipe diameters away from any turbulence. Turbulence can occur around elbows, fittings, and other valves. To ensure proper orientation, check the valve for a flow arrow on the tag or on the valve itself.

141 check valve

A 141 custom check valve regulates fluid pressure for precision system control. These valves are an integral part of stop/start systems, which are used to improve fuel efficiency and reduce emissions. Precise fluid pressure regulation is critical for this function, as it ensures a seamless shutoff and restart without loss of pressure. A custom check valve is capable of optimizing fluid pressure in fractions of a second, which makes it an important part of stop/start systems.

These valves are commonly used in corrosive environments, such as pulp and paper mills and chemical processing. These valves have a durable stainless steel body and check, as well as a unique bubble-tight shutoff. Other features of this valve include an investment-cast stainless steel body, center guided alignment, and straight-through flow. You can also select from a variety of styles to suit your needs. They are a valuable part of HVAC systems, and are used to prevent backflow.

Butterfly check valve

A butterfly valve is a valve with a rotary disc that rotates 90 degrees. This type of valve is popular for many industrial processes and can be manufactured with various materials, depending on the purpose. Custom butterfly valves can also be made with large valve bodies for applications in ventilation ducts. If you need a custom butterfly valve, COVNA can provide you with the exact design you need.

Butterfly check valves can be manufactured to meet a variety of safety and quality standards. Some American organizations have set standards for these valves, including the American Society of Mechanical Engineers (ASME), the American Petroleum Institute (API), and the Manufacturers Standardization Society. International organizations such as the European Committee for Standardization (CEN) also put quality standards for butterfly valves. To find a custom butterfly check valve, contact an expert in the field and let them design the perfect valve for your application.

Folding disc check valve

A folding disc check valve is a simple type of valve with two halves that are attached together in the center. The disc swings away from the valve seat when upstream flow is stopped, and then returns to the seat to allow reverse flow to pass. A basic check valve consists of a valve body, bonnet, and cover, with a hinge that allows the disc to swing back toward the valve seat when upstream flow stops. This type of valve is often used in applications where space is a constraint, but there are many uses for it.

Tilting disc check valves are another type of valve. Tilting discs have a pivot point in the center, and fluid flows over the top and bottom of the disc. Unlike swing check valves, tilting disc check valves stay open even when flow reverses. They have a low pressure drop and higher flow rates than swing check valves. However, these valves tend to open and close rapidly, so they're best suited for low and high-flow applications.

Spring check valve

The design of a check valve is relatively simple. When manufacturers sketch the product diagram, a few important things are considered. In this way, they can ensure that materials flow through the valve without causing backflow. The following are a few tips for choosing a spring for your check valve. These tips will help you select the perfect spring for your specific needs. However, you should know that you should also consider the material used for the spring itself.

The material used to manufacture a check valve can also be important. The body of a spring check valve is usually made of steel or other corrosion-resistant material. Stainless steel and iron are popular choices, because of their durability and ability to withstand pressure. Another important feature to look for in a spring check valve is its seal, which is the best choice for preventing backflow. These valves are available in different sizes, and you should know how to select the right one for your application.

Wafer check valve

A custom Wafer check valve is designed for a specific application. The wafer style body is 125#, and this check valve is available in many configurations. The wafer-style body prevents upstream flow while allowing only one direction of flow. They are also available with bumpers and long-life discs to minimize internal wear and tear. These valves are available for immediate shipment. If you have a special configuration in mind, contact our team today.
