Quadax® butterfly valves

Quadax® butterfly valves are the ideal solution for demanding customers with the highest requirements for tightness and reliability—for extreme applications and temperature ranges.
 
Quadax®  develops and manufactures premium valves that perform where others fail—at temperatures ranging from –270 °C to +800 °C, under maximum pressure, in critical industries worldwide. With its unique 4-offset design, and state-of-the-art manufacturing technology, QUADAX® meets the most demanding requirements, even in extreme pressure and temperature ranges.

Types
FLEXIBLE, RELIABLE, HIGH-QUALITY, ROBUST

This version is equipped with a flange on both ends and is connected to the piping via a bolt-and-nut joint. It is the shortest design after the flanged version.

technical data sheet
COMPACT, DURABLE, RELIABLE, ROBUST

In the lugged version with threaded flange holes, the valve is bolted directly to the pipe flanges on both sides. It has the shortest overall length and can therefore be installed in the piping system in a very space-saving manner.

Design:4-Offset (TOV upgraded)

technical data sheet
DIRECT REPLACEMENT, HIGH RELIABILITY, LOW EMISSIONS

The design of the gate valve replacement was developed to allow for the replacement of a all valves with ASME B16.10 face-to-face length (ball valve, gate valve, globe valve) without modifying the piping. Unlike other valve designs, using the Quadax® gate valve replacement saves space and weight and also reduces the cost of your system.

Design:4-Offset (TOV upgraded)
Pressure range:PN 10–100 / ANSI 150–600
Nominal size:DN 80–1000 / 3″-40″
Connection:Flange
Temperature range:-270 °C / -454 °F to +800 °C / 1472 °F

INDUSTRIES:

Chemicals and Petrochemicals, Cryogenics, Oil and Gas, Hydrogen (H2), Power Generation, District Heating

technical data sheet
ZERO LEKAGE, ROBUST, HIGH SEALING PERFORMANCE

The buttweld version is primarily used in long-distance pipelines. With this version, which has no flanged connections, the risk of undetected leaks is significantly reduced.

Design:4-Offset (TOV upgraded)
Pressure range:PN 10–160 / ANSI 150–1500
Nominal size:DN 80–1800 mm / 3″-72″
Connection:Welded ends
Temperature range:-270 °C / -454 °F to +800 °C / 1472 °F

INDUSTRIES:

Petrochemicals and chemicals, aerospace, oxygen, cryogenics, oil and gas, hydrogen (H2), power generation, district heating, industrial gases, solar thermal, shipbuilding

technical data sheet
EASY TO MAINTAIN, CRYO-DESIGN, ZERO LEKAGE, SAFETY

To perform maintenance on the valve, all internal components can be removed through the top access point while the body remains in the pipeline. The top-entry version is primarily used in pipelines or LNG Terminals, where flanged connections must be avoided.

Design:4-Offset (TOV upgraded)
Pressure range:PN 10–160 / ANSI 150–900
Nominal size:DN 100–1000 mm / 4″-40″
Connection:Welded ends
Temperature range:-270 °C / -454 °F to 538 °C / 1000 °F

INDUSTRIES:

LNG, petrochemicals and chemicals, aerospace, oxygen, cryogenics, hydrogen (H2), shipbuilding
