Tilting Butterfly Type Check Valve Without Hydraulic

The tilting butterfly type check valve without hydraulic is one of the check valve series manufactured by FYL. The purpose of using this kind of valve is to prevent fluid backflow in pipelines and systems. The design of no hydraulic equipment can help to improve efficiency, and the tilting butterfly design is more conducive to the automatic adjustment of flow direction, achieving the seamless control of fluid.

Why FYL? Stop Paying for Hydraulic Leaks.

While conventional hydraulic-dependent check valves constantly risk oil leakage, vane jamming, and costly maintenance, FYL introduces a fundamentally smarter solution—the Tilting Butterfly Type Check Valve Without Hydraulic.

This is not just “no hydraulics.” This is mission-critical reliability for your continuous operation.

Your immediate gains vs. traditional valves:

• Zero hydraulic leakage → No oil contamination to media, no fire hazard.
• Instant self-actuation → No pump delay caused by slow hydraulic response.
• Lowest life-cycle cost → No hydraulic oil top-up, no seal replacement.

Engineered for Efficiency: ΔP as Low as <XX kPa

Most “low resistance” claims are vague. We provide measurable results.

The FYL tilting disc design achieves an extremely low pressure drop (ΔP) at full opening. The disc rotates into a streamlined position, literally “disappearing” into the flow path.

Result: Up to [XX]% energy saving on each pump stroke compared to swing or lift check valves.

Why it matters for you: Lower pump energy = direct OPEX reduction month after month.

Built for Harsh Media

We selected raw materials not for “general industry” but for real-world punishment.

For power plants: Handles superheated steam <80°C (and available high-temp version) without diaphragm failure.

For dusty air: The tilting action self-flushes debris—no sticking like spring-loaded types.

For chemical lines: Available in corrosion-resistant internals (not just standard).

Where This Valve Wins

Replace hydraulic check valves in thermal power circulating water: No more oil spills into cooling towers.

Upgrade sewage pump stations: Handles debris-laden water where hydraulic ports would clog.

Chemical plant reactor outlet: Eliminates risk of incompatible hydraulic oil mixing with process media.
