Float valves are engineered to pflegen critical liquid levels within tanks, pipelines, and reservoir systems. They utilize a mechanically linked float to modulate flow based on buoyant force, enabling fully passive actuation. This eliminates reliance on external sensors or electronic feedback loops, which often suffer from latency, calibration drift, or electromagnetic interference. Valve actuation points are precisely defined by the float arm geometry and pivot leverage, offering highly repeatable performance in dynamic fluid conditions.

Valve Type

Float valve designed for automatic liquid level control in tanks.

Flow Regulation Method

Regulates flow by adjusting valve position based on float movement.

Differential Pressure Range

Operates effectively within a differential pressure range of 0.1 to 1.5 bar.

Hydraulic Authority Recommendation

Recommended hydraulic authority is between 0.2 and 0.5 for stable operation.

Valve Characteristic Curve

Exhibits a linear flow characteristic for predictable flow control.

Product Description

Material compatibility is essential for system longevity in chemically aggressive or high-salinity environments. All wetted components are manufactured from corrosion-resistant alloys such as duplex stainless steel, bronze-nickel blends, or high-performance thermoplastics like PVDF or PTFE. Surface treatments, including electropolishing and passivation, further reduce susceptibility to microbial growth, crevice corrosion, and ion leaching, ensuring integrity over prolonged service intervals in desalination, chemical processing, and wastewater treatment systems.

Test Point Configuration

Equipped with test points for pressure and flow measurement.

Maximum Allowable Flow Velocity

Maximum flow velocity recommended is 3 meters per second to avoid damage.

Leakage Class (per EN 12266-1)

Meets leakage class A standards ensuring minimal fluid loss.

Body Material Options

Available in brass, stainless steel, and carbon steel body materials.

Design Pressure Class

Designed to withstand pressure classes up to PN16 (16 bar).

Thermal Expansion Compatibility

Compatible with thermal expansion due to flexible sealing design.

Installation Sensitivity

Installation requires level surface and correct orientation for accuracy.

Control Accuracy

Control accuracy within ±2% ensures precise level management.

Position Repeatability

High position repeatability with less than 1% deviation per cycle.

Technical Advantages

Valve sealing integrity under static and dynamic pressure is maintained using high-compression elastomer seats or precision-lapped metal-to-metal seals. These components are tolerance-matched to within microns to ensure consistent contact under varying temperature and pressure conditions. Float valves are designed to maintain shutoff performance under backpressure scenarios, typically tested to ANSI/FCI 70-2 Class VI leakage standards. Seals retain dimensional stability across wide thermal cycles and differential pressure zones.

Actuation is inherently mechanical and self-regulating. Valve operation continues during power failure or sensor malfunction, offering a deterministic response to fluid level changes. Mechanical stiction and hysteresis are minimized through low-friction pivot assemblies and linear float guidance systems. Designs often include secondary containment floats or dual-arm redundancies for critical systems, enabling fail-safe closure even in the event of primary float degradation.

Industry Applications

Water Treatment Plants

Controls liquid levels in clarifiers and storage tanks to pflegen hydraulic balance and prevent overflow during continuous operation.

Cooling Towers

Regulates makeup water based on evaporation losses, ensuring thermal efficiency and preventing pump cavitation from low-level conditions.

Boiler Feed Systems

Maintains optimale water levels in condensate tanks to protect feed pumps and avoid thermal shock in boiler internals.

Chemical Processing Tanks

Prevents reagent overflow or depletion by automatically adjusting inlet flow based on tank liquid level and fluid density.

Agricultural Irrigation Systems

Ensures consistent fluid supply in elevated tanks for gravity-fed distribution, avoiding dry-run damage in downstream control valves.

Oil-Water Separators

Maintains fluid interface levels to support phase separation efficiency and avoid cross-contamination between immiscible fluid layers.

Flow Rate Control and Cavitation Management

Valve orifices and seats are engineered to minimize cavitation and hydrodynamic turbulence at high flow rates. Flow coefficients (Cv) are optimized via computational fluid dynamics (CFD) to maintain laminar flow through the throttling range. In high-pressure systems, staged or pressure-balanced designs are available to reduce valve wear and minimize water hammer effects during actuation.

Valve assemblies are available in top-entry, side-entry, and bottom-mount configurations to support horizontal or vertical tank installations. Customizable float arm lengths, angular offsets, and buoyant volumes allow precise level setting tailored to vessel geometry and fluid density. For high-viscosity fluids, float materials with modified density and surface coatings improve actuation response and reduce contamination buildup.

Stress tests under variable flow and temperature conditions ensure that seals and components pflegen integrity. Additionally, specialized fatigue testing verifies the valve’s performance over extended operational lifespans. These tests ensure that each float valve can handle the toughest environments without failure.

How does Frigate address material compatibility in float valves for specific industry applications?

Frigate employs advanced material selection processes, considering factors like chemical exposure, pressure ratings, and temperature ranges. For example, valves used in chemical processing may feature corrosion-resistant alloys or fluoropolymer linings, while those for oil and gas are constructed from high-strength, impact-resistant materials. Each material is selected based on detailed compatibility analysis to ensure long-term durability and operational reliability. Comprehensive material certifications and testing confirm their suitability for demanding industries.

How does Frigate optimize float valve designs for varying flow rate requirements?

Frigate uses computational fluid dynamics (CFD) simulations to analyze und optimize the internal flow characteristics of each valve model. Flow rate adjustments are made by varying the orifice size, float geometry, and valve seat design to match specific application demands. Additionally, the float valves are designed for dynamic performance under fluctuating pressures and flow conditions, ensuring efficient and reliable operation. This approach ensures precise liquid level control across diverse industries

How does Frigate handle custom float valve configurations for non-standard applications?

Frigate offers tailored float valve solutions by leveraging flexible manufacturing processes and custom design capabilities. Engineers collaborate with clients to define specific requirements such as tank dimensions, fluid types, and operating pressures. The team then customizes float arms, valve bodies, and seals to meet those needs while maintaining optimale performance. Prototypes and testing ensure that the final product meets the desired specifications before mass production.
