Precision Butterfly Valves for Industrial Flow Control

Pressure Rating: Low to Medium (PN10 / PN16). Ideal for standard municipal water distribution and HVAC loops.

Temperature Range: -20°C to +120°C depending on seat elastomer.

Seat Material: EPDM, NBR, or PTFE liners providing tight shutoff for potable water and non-corrosive gases.

Connection Standard: DIN EN 558 Series 1 / ASME B16.1. Lightweight design fits easily between flanges with minimal bolt torque.

Pressure Rating: Low to High (Up to PN40). Designed for process industries where isolation is critical.

Temperature Range: -20°C to +150°C.

Seat Material: Reinforced PTFE or Metal-faced seats for chemical resistance in aggressive processing environments.

Connection Standard: Threaded lug holes allow installation at the end of a pipeline, enabling one side to be disconnected for maintenance without draining the entire system.

Pressure Rating: Medium to High (PN16 – PN64). Built for large-diameter municipal pipelines and heavy-duty water treatment plants.

Temperature Range: Up to +150°C.

Seat Material: Heavy-duty rubber or PTFE composites designed to withstand high-flow turbulence.

Connection Standard: Flanges on both ends bolt directly to pipe flanges, eliminating the need for additional spool pieces and ensuring maximum structural rigidity.

Pressure Rating: Low to Medium. The standard choice for general water supply and low-pressure HVAC applications.

Temperature Range: -10°C to +110°C.

Seat Material: Elastomeric seats (EPDM/NBR) that compress around the disc for bubble-tight shutoff in clean fluids.

Connection Standard: Typically wafer-style. The stem passes through the exact center of the disc, rotating concentrically with the seat.

Pressure Rating: Medium to High (Class 150 – Class 300). Engineered for demanding Oil & Gas and Chemical Processing services.

Temperature Range: -46°C to +425°C depending on metal/PTFE seating.

Seat Material: Precision PTFE or Metal seats. The double offset design lifts the disc off the seat immediately upon opening, reducing friction and wear.

Connection Standard: Wafer or ANSI Flange connections. Offers superior torque reduction compared to concentric designs.

Pressure Rating: High Pressure (Class 150 – Class 2500). Used in severe service applications like refineries and LNG terminals.

Temperature Range: Cryogenic temperatures up to +870°C+.

Seat Material: Metal-to-metal sealing arrangement (e.g., Stellite, Inconel). Provides absolute zero-leakage even under extreme thermal cycling.

Connection Standard: Weld-end or heavy flange connections. The triple offset angle ensures the disc never rubs against the seat until fully seated.
