EV-Alu Lightweight quality


Cast aluminium valve to suit applications where lightweight is an absolute must. Based on proven Wouter Witzel technologies, like fully vulcanized to the body bonded liner and standard duplex trim. Suitable for maximum 20bar differential pressure. Available in wafer style DN50-300.

USP's aluminium Valve

1. ISO 5211 Actuator mounting pad

2. Cast aluminium Alloy body

Light, though strong: up to 20bar working pressure

3. Reliable

Lifetime, leak tight, low operation torque, vacuum and extreme high number of operations allowed

4. Lightweight components

Bearings and seal bushes made in  lightweight POM

5. Copper free sealing

Preventing galvanic corrosion



Saving weight on any mobile equipment (vehicles) will automatically result in energy saving. Savings create freedom to i.e. reduce costs or to add more/other components in (often) weight constraints. Components like valves therefore, are more and more required to be light weight but reliable and durable at the same time.

Saving weight on above waterline systems is creating more stability on Ships. It also reduces the weight of the ship. An other advantage is, that the aluminium valve is Anti-magnetic and will never cause any friction.

Avilable with the following characteristics:

  • 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 (TSO).
  • Available in Wafer type.
  • DN 40 (1.5″) – 300 (12″), bar rated
  • Average weight saving 50%, compared to cast iron valves.
