Description

Flanged Pilot-Assisted Float Control Valve – Z-Tide Industrial BFF-D Series


The Z-Tide Industrial BFF-D Series is a heavy-duty flanged pilot-assisted float control valve designed to automatically maintain liquid levels in storage tanks, reservoirs and process vessels without electrical power. Using a remotely mounted float pilot and pressure-assisted piston, the valve automatically opens as the liquid level falls and closes progressively as the preset level is reached, providing high-flow automatic tank filling while helping to reduce hydraulic shock.

Performance & design

✓ Patented cylindrical piston design
✓ Exceptionally high flow capacity compared with conventional float control valves
✓ Straight-through flow path reduces pressure loss, turbulence and hydraulic noise
✓ Remote float pilot allows the main valve to be installed outside the tank for easier servicing
✓ Externally mounted pilot controller allows maintenance without removing the main valve body from the pipeline
✓ Unique U-ring sealing system provides long, reliable, maintenance-free service
✓ Automatic opening and closing provides accurate liquid level control without electrical power

Applications

Storage tank level control
Reservoir filling systems
Water storage tanks
Process tanks
Cooling water systems
Industrial water distribution
Fire water storage systems
Municipal water infrastructure
General industrial process control

Manufacturing quality

Manufactured using a heavy-duty epoxy-coated ductile iron body with bronze piston and precision-machined bronze, brass and stainless steel internal components, the Z-Tide Industrial BFF-D Series has been engineered for reliable long-term operation in demanding industrial environments. The remotely mounted float pilot valve continuously monitors the liquid level within the tank and controls the main valve through a simple pilot pressure system. As the liquid level falls, the float pilot releases pressure from the control chamber, allowing the main valve to open rapidly and refill the tank. As the tank reaches the preset level, the float pilot closes, pressure builds within the control chamber and the main valve closes progressively to minimise hydraulic shock. The patented cylindrical piston design provides exceptionally high flow capacity while allowing the main valve to be mounted outside the reservoir for straightforward inspection and maintenance.

Ordering information

Simply select the required flange size, seal material and flange standard before adding the valve to your basket. A compatible ½" float pilot valve is required for operation and is available separately. Alternative flange standards, seal materials and custom sizes up to 56" are available on request.
