Resilient seated butterfly valves with valve body and disc in high engineered composite material providing excellent internal and external chemical resistance

Since the entire valve exists of high engineered composite materials, it is perfectly suited for
a wide range of applications such as; building services, hot water applications, industrial waste water and industrial water treatment like purification, ozone or demineralization.

The light weight valve can be perfectly used in transportation and cargo containers and in applications using metal, plastic or glass reinforced pipe lines.

Patented wafer style body and disc in high engineered composite results in excellent internal and external chemical resistance.

• Light weight construction results in lower cost and simplified installation.

• No extra pipe support needed when installed in plastic or GRP piping.

• Disc in high engineered composite material provides excellent corrosion resistance.

• All fasteners in stainless steel 316 as standard.

• Bubble tight shut-off in both directions, in accordance with EN 12266-1 leakrate A.

• Pressure range up to PN 16 at elevated temperature.

• Valve can be used in high line velocity applications up to 12 m/sec.

• Spindle and primary valve seals are not influenced by the flange bolting force or pipe flange type.

• High Kv (Cv) value.
• No need for flange gaskets.
• Primary stem sealing exceeds the pressure

rating of the valve and prevents leakage

through the shaft area to atmosphere.
• A secondary (shaft) sealing provides back-up

• 4 integrated locating holes ease installation

and centering between the pipe flanges. • Actuator flange acc. ISO 5211.
• Sustainable production philosophy as the

valve materials are 100% recyclable.
• Use of composite material eliminates the

need for machining and painting.
• Composite hand lever available.
• Available water approvals: KIWA, ACS, WRAS,

• Certified and approved according Det Norske

Veritas (DNV).
