Grooved Swing Check Valve
It trades the ultra-high pressure capability of flanged valves for significant gains in installation speed, flexibility, and cost-effectiveness. It is the go-to choice for a massive range of commercial and industrial building systems, especially fire protection.

Details Description
Grooved Swing Check Valve is a type of check valve that uses the same swinging disc mechanism to prevent backflow but is designed with grooved ends for a mechanical coupling connection instead of flanges. This grooved design allows for much faster installation and disassembly using a pair of coupling housings and nuts and bolts.
The core internal function—swinging open with forward flow and closing with gravity and backflow—is identical to a flanged swing check valve.
Features
• Faster Installation: Significantly quicker to install than welding or bolting flanges. Just two couplings connect the valve.
• Economical: Lower installed cost due to reduced labor time and no need for welders or large torque tools for bolts.
• Flexibility & Maintenance: Allows for easy disassembly for system modifications, inspection, or valve replacement.
• Pre-Assembled Couplings: The gasket in the coupling can absorb vibration and dampen sound, slightly reducing water hammer noise transmission.
• Safety: No hot work (welding) is required for installation, which is a major safety benefit on site.

FAQ
Q：Are there any special orientation requirements for the installation of grooved swing check valves?
A：Yes, it must be installed horizontally and it is necessary to ensure that the rotation shaft of the valve disc is in a horizontal position. This is the absolute prerequisite for its working principle. The valve disc needs to rely on gravity to move back and forth and close. Vertical or inclined installation is strictly prohibited; otherwise, it will cause the valve to fail to work properly or completely fail.
Q：Is it applicable to the fire protection system?
A：Yes, this is one of its main application scenarios. It is often installed at the outlet of the fire pump to prevent water from flowing back in the water supply network.
Q：Can OEM services be provided? For example, putting on our brand Logo?
A：Of course! As a factory, we warmly welcome OEM/ODM cooperation.
Q：What is your payment terms?
A：Payment supports T/T, L/C, etc. We also support payment via wechat or Alipay.
Q：What is the delivery time?
A：The production usually takes 15 to 30 days. For large or special orders, it may take 60 days or longer. We will provide you with an accurate production plan after placing your order
