Ball Check Valve FBCV
The KV Controls FBCV Ball Check Valve provides automatic backflow prevention for water and sewage pumping systems. Its rotating ball supports self-cleaning action, while the full-bore design helps minimise pressure loss. A removable bonnet provides access for cleaning or ball replacement without removing the valve body from the pipeline. Available in sizes DN50–DN600, subject to configuration confirmation.
FBCV Ball Check Valve for Water and Sewage Systems
The KV Controls FBCV Ball Check Valve is an automatic non-return valve designed to prevent reverse flow in water supply, sewage and pumping applications. Its simple operating mechanism uses a spherical ball as the moving closure element.
Forward flow lifts the ball away from the seat, allowing fluid to pass through the valve. When flow reverses, the ball returns to the seat to block backflow. The ball rotates during operation, supporting a self-cleaning action that helps limit deposits on its surface.
Features and Benefits
- Automatic backflow prevention: Helps protect pumps and connected systems against reverse flow.
- Self-cleaning ball action: Rotation during operation helps discourage deposit build-up.
- Full-bore design: Provides an open flow path designed to minimise pressure loss.
- Accessible maintenance: A removable bonnet allows access for cleaning and ball replacement without removing the valve body from the pipeline.
- Protective coating: Internal and external epoxy coating helps protect coated surfaces against corrosion.
- Installation flexibility: Horizontal and vertical installation options, subject to confirmation of flow direction and operating conditions.
Typical Applications
The FBCV ball check valve is intended for:
- Sewage pumping systems.
- Water pumping stations.
- Water supply networks.
- Water treatment and distribution systems.
- Power-station cooling lines.
- Compatible industrial water applications.

Specify Your FBCV Ball Check Valve
Confirm valve size, flow rate, operating pressure, temperature, installation orientation and the nature of any solids before selection. Available combinations of size, pressure rating, materials and connections must be verified for the application.
