Product Description

 

Product Description

Describtion:

The non-wear spherical check valve uses a rubber ball as the disc. It rolls inside the valve body to open/close, offering high flow, low resistance, good sealing, and silent closing to reduce water hammer. It can be installed horizontally or vertically at pump outlets in water supply networks to prevent backflow.

Features:
 

• Good Sealing Performance: The valve disc is a rubber-covered rolling ball, which rolls under the action of the medium to open and close the valve, ensuring good sealing when closed.
• Wear-Free: The valve disc is a rubber ball with no shaft or bearing components. The ball is in a free-floating and rotating state, with even wear and long service life.
• Noise Reduction and Shock Absorption: Silent closing without water hammer, and minimal impact vibration during closure.
• Low Resistance: The valve body features a full-flow channel, resulting in high flow capacity, low resistance, and 50% less head loss compared to swing-check valves.
• Flexible Installation: Can be installed either horizontally or vertically.
• Simple Structure: Composed of a valve body, partition plate, and ball assembly, it is easy to manufacture and requires no maintenance during use.
• High Versatility: Only two types of ball assemblies are used, and by varying their quantity and arrangement on the partition plate, multiple product sizes can be achieved.
