2 Inch Check Valve

Product Description

2 inch check valve: It is a valve that can automatically prevent the backflow of fluid. The disc of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve disc will automatically close under the action of fluid pressure difference, gravity and other factors to prevent the fluid from flowing back. The product is designed and manufactured in strict accordance with GB12235 standard. The valve disc moves up and down along the center. The bushing is made of special materials with good wear resistance and small friction coefficient. The action is flexible and reliable, and the sealing performance is excellent.

There are a variety of check valve models available on the market today, as check valves can be designed to suit specific applications. Therefore, it is important for businesses to take the time to research the specifications of check valve products to determine which products can meet certain expectations. Some typical check valves are in constant demand across industries, including swing check valves, lift check valves, line check valves, diaphragm check valves, and ball check valves. The correct form of check valve for a business depends largely on its intended application. In some cases, the customer may request the manufacturer to manufacture the check valve according to specific design requirements.

Features

These valves are typically used in sizes 2 inches and above. Swing check valves can be installed in both horizontal and vertical positions. They are not suitable for pulsating flow. Swing check valves have a slower closing response than lift check valves because of the longer disc travel and greater disc inertia.
