Description

Stainless Steel Balanced Float Ball Valve – Z-Tide Industrial FBV Series

The Z-Tide Industrial FBV Series is a premium balanced mechanical float ball valve designed for accurate automatic water level control in tanks, reservoirs and process vessels. Manufactured from 304 stainless steel throughout, the balanced piston design provides exceptionally smooth operation with reduced closing force, allowing the use of a smaller float ball and shorter lever arm than conventional float valves. Suitable for threaded and flanged installations, the FBV Series delivers reliable, maintenance-free level control for industrial water systems while also serving as the pilot float valve for the Z-Tide BFF automatic float control valve range.

Manufacturing quality

Manufactured entirely from 304 stainless steel with precision-machined internal components, the Z-Tide Industrial FBV Series has been engineered for reliable long-term operation in demanding industrial environments. Its balanced piston design significantly reduces the force required to close the valve, allowing the use of a compact float assembly while maintaining accurate level control at higher operating pressures. The patented lever linkage provides simple level adjustment without bending the float arm, while the full-flow construction delivers rapid tank filling with minimal splash and turbulence. The FBV Series also functions as the recommended pilot float valve for the Z-Tide BFF automatic float control valve range, providing dependable remote level control for large industrial storage tanks.

Ordering information

Simply select the required thread or flange size, seal material and pressure option before adding the valve to your basket. Optional NPT threads, PN16 flanges, Viton seals, high-pressure versions and all-silicone seals for temperatures up to +150°C are available on request.

Well made BUT the ball is undersized / or/ arm too short and ball goes well down in water before shut off is achieved. Hi John. Thanks for the review – I thought I should reply. The valve is fully adjustable but if this isn't enough for your application and feel free to bend the arm (Its strong stainless) but do this in small increments as straightening it again would weaken it. Thanks + Best Regards Mike (Connexion Developments Ltd T/A Solenoid Valve World)
