Materials

A wide selection of materials are available ranging from carbon steels,
stainless steels (including duplex, superduplex and superaustenitic), Ni
alloys (up to Inconel 625 and incoloy 825) and other advanced materials.
Split body valves are generally made from forged or centrifugal casting,
whereas top entry valves are generally manufactured from cast material. All
the materials are supplied from approved sources and the characteristics
of all the materials may be supplied as per specific requirements.

Operation
Valpres valves can be supplied with a manual lever/ gearbox or with
any type of actuator. All valves are tested as a package prior to delivery.
We can also supply the complete valve and actuator package including
pneumatic or electric actuators.
Temperature range -196°C (-320°F) to +350°C (+675°F).
