Hydraulic Control
Metal / Soft Seal
Butterfly Valve

Metal Seal Counter-weight butterfly valve with hydraulic station

This valve is actuated by a hydraulic power station, enabling rapid and precise operation even in large diameters. Unlike traditional valves that require a gearbox for torque multiplication, the hydraulic actuator delivers direct, high-force movement without mechanical reduction. This eliminates the delay associated with gear-driven systems, allowing for exceptionally fast opening and closing times. Ideal for critical applications where speed and responsiveness are essential—such as emergency shutdown, surge control, or high-flow industrial processes—this valve combines power, reliability, and efficiency in a compact, robust design.

Features & Benefits

Direct Hydraulic Power Actuation
Actuated by a hydraulic power station, the valve delivers high-force, precise control without the need for gearboxes. This enables exceptionally fast opening and closing, even in large-diameter systems.

Engineered for Critical Water Applications
Designed specifically for water treatment and transmission systems where speed, reliability, and non-slam performance are essential—such as emergency shutdowns and surge control.

Triple- or Double-Eccentric Sealing Structure
Features an eccentric disc and seat design that minimizes friction, reduces wear, and provides reliable bidirectional sealing performance.

Non-Slam Operation
Hydraulic control ensures smooth disc movement, eliminating water hammer and pressure surges during closure.

Large Diameter Capability
Ideal for large-scale systems, maintaining full sealing and operational reliability in high-volume flow conditions.

Corrosion and Wear Resistant
Built to withstand the demanding conditions of both raw and treated water, offering long-term performance with minimal maintenance.

Simplified Maintenance
Fewer mechanical components mean lower maintenance requirements and reduced operational downtime.
