Bronze Dual Plate Check Valve‌‌

Waits Valve bronze dual plate check valve is a good choice. It has high quality seal, fast response, durable bronze structure and space-saving design. It is suitable for a variety of media. At the same time, the dual plate structure improves the sealing performance, and the gentle closing of the gate reduces the water hammer effect, which can achieve a smooth non-return flow! Waits Valve firmly believes that quality builds global confidence.

Product Description

The Bronze Dual Plate Check Valve produced by Waits Valve factory is a compact, light, fast opening and closing check device. It consists of two symmetrical butterfly valve discs. It opens when the medium flows forward and closes quickly when it flows reversely, effectively preventing fluid backflow and reducing the risk of water hammer. It is suitable for occasions with high requirements for sealing, such as pipelines in the chemical, pharmaceutical and other industries that transport certain corrosive or precious media, as well as some pipeline systems that have strict requirements for preventing medium backflow.

Scope of application
Products are suitable for pipeline systems in various fields. In civil and industrial water supply and drainage scenarios, they can be used in tap water and sewage pipelines to prevent water backflow. In heating and chilled water pipelines of HVAC systems, they can avoid medium backflow affecting system balance. In seawater, freshwater, and ballast water pipelines of marine and ocean engineering, they can resist corrosion and prevent fluid backflow. In production lines of the food and beverage industry, they meet hygiene standards and prevent medium contamination by virtue of food grade bronze materials. They can also be applied to pipelines of small scale heating and kitchen equipment in low pressure steam systems to prevent steam backflow, and some products are also suitable for use with water pumps in fire water pipelines.

Feature:

Bronze Dual Plate Check Valve‌‌ adopts a wafer type design with a short installation length, suitable for occasions with limited space.
The double disc structure opens sensitively and closes quickly, significantly reducing the water hammer effect.
Compared with traditional cast iron or steel valves, the bronze material of Bronze Dual Plate Check Valve‌‌ is lighter, more corrosion-resistant, and easy to install and maintain.
EPDM, NBR or PTFE seals can be configured to meet different media and temperature requirements.
Can be installed horizontally or vertically (media flows upward), with strong adaptability.
