Company Introduction Duvalco Valves was founded 1956 with the goal of building high‐quality 

butterfly valves for the marine and ship‐building industries.

One of the first company to produce butterfly valve in Europe

Produce butterfly for the shipbuilding and marine industryProduce butterfly for the shipbuilding and marine industry

The company was later renamed as Duvalco (Dutch Valve Company)

In the period since then, Duvalco has expanded its product line to serve civil engineering, water treatment, industrial and construction industries and served markets globally. 

In 2006, Duvalco expanded its manufacturing capacity and established it corporate headquarters to  Asia to focus on its growing customer base and

Partnership with VIP

There are only several valve manufacturers in the world that offer their own in-house rubber manufacturing.

Among them, we have some of the most unique and cost-effective solutions.

Our partnership with VIP Polymers allows us to create and offer specialized and high-quality polymer materials for sealing our valves in almost any condition.

We would like emphasize and leverage this relationship.

Duvalco Bonded Liner

The bonded liner creates a 100% tight-off on the process connections due to extended rubber

lining beyond the flanges facing, no flange gasket required.

The bonded liner concept will create a corrosion proof design, complete elimination between

body and liner. Bonded liner fully covers the valve body internally.

All our valves are suitable for vacuum (negative pressure) services and high fluid velocity

applications. (Ensure that liner will not be sucked into the pipeline).

Duvalco Bonded liner concept ensures that the liner cannot move around which give you the

following advantages;

• No tearing and distortion of the liner

• Very low wear of the seat

• Reliable low torque figures• Reliable low torque figures

• Exceptionally long seat life up to 3 x longer than replaceable liner valves

• Permanent dry lubrication free design due to stainless steel stem and bronze bearings

• Uniform sealing bi-directional flow

29

• Uniform sealing, bi-directional flow

TM

Why Bonded Liner?

Replaceable liner –

When sandwiched between flanges the liner is compressed across its width and can bulge out towards the disc.

Load from disc results in further distortion of liner creating higher closing loads and increased wear and abrasion.

Duvalco bonded liner –

Liner is bonded to metal across whole width of valve bodyLiner is bonded to metal across whole width of valve body, resulting in a smooth profile, lower closing torques and reduced wear. Lower torques mean smaller gearboxes and actuators.
