Wouter Witzel have expanded their range of butterfly valves by introducing the ”EV-Alu” cast aluminium butterfly valve to suit applications where a lightweight solution is an absolute must.

As with all Wouter Witzel rubber lined butterfly valves, this product features low operating torque, long durability and can be mounted without the use of external gaskets. It is also covered by their standard five year warranty.

Features include:
• ISO 5211 actuator mounting pad.
• Cast aluminium alloy body: light, though strong: up to max 20 bar working pressure.
• Vulcanized elastomer seat: vacuum proof, low operation torque, high frequency of operation.
• Lightweight components; even the bearings used are made from lightweight POM material

Saving weight on above waterline systems creates more stability on ships. It also reduces the weight of the ship. Another advantage is that the aluminium valve is anti-magnetic and so will never cause any friction.

The new “EV-Alu” is light weight but reliable and durable at the same time. The unique selling points are:
• Anodized body, guarantees a high corrosion resistance and scratch proof.
• Body material cast aluminium alloy (EN AC-42100).
• Easy installation (integrated flange gasket).
• Bi-directional tight shut off.
• Available in wafer type.
• DN40 (1.1/2”) To DN300 (12”)
• 50% average weight saving compared to cast iron valves.
