Description

Flanged Stainless Steel Pilot-Assisted Float Control Valve – Z-Tide Industrial BFF-S Series


The Z-Tide Industrial BFF-S Series is a premium flanged pilot-assisted float control valve designed to automatically maintain liquid levels in storage tanks, reservoirs and process vessels without electrical power. Manufactured in 304 or 316 stainless steel and rated for working pressures from 0.5 to 25 Bar, the BFF-S combines excellent corrosion resistance with exceptionally high flow capacity for demanding industrial applications.

A remotely mounted float pilot controls the pressure-assisted main valve, automatically opening to refill the tank as the liquid level falls and closing progressively once the required level is reached, helping to minimise hydraulic shock.

General industrial process control

Manufacturing quality

Manufactured using heavy-duty 304 or 316 stainless steel with precision-machined stainless steel internal components, the Z-Tide Industrial BFF-S Series has been engineered for demanding industrial environments where corrosion resistance, reliability and automatic liquid level control are essential. 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 installed outside the reservoir, simplifying inspection, servicing and long-term maintenance.

Ordering information

Simply select the required body material (304 or 316 stainless steel), 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 DN1400 (56") are available on request.
