We are currently producing a new cast gate valve DN700 PN40

Due to the currently signed nuclear valve supply projects, we had to make design modifications to our existing Gate Valve S38 and thus expand our existing product portfolio.

In the design of the cast gate valve, we have taken advantage of the possibility to reduce the flow rate, while satisfying the condition of a loss factor of up to 1. This design condition allowed us to reduce the internal parts of the gate valve, reduce the weight and the actuation torques for opening and closing.

It was also necessary to create new body castings, which are designed without sprues on the body shell and the inlet system is through the flow and the third flange.  This casting provides us with high quality in the area of the weld ends, where we carry out all the necessary checks, including X-raying, after roughening the shape of the ends.

The quality of the welds in the body is guaranteed by the embedded saddle rings with Stellite 6 welds.

We produce cast gate valves from material variants:

• Carbon version
• Alloy design
• Stainless steel version

The design pressure Pp 2,5MPa for the stainless steel version is 1,6MPa

Calculation temperature 250°C

The new cast gate valves are manufactured in a weld-on design with operating

• Electric actuator AUMA SA25.1
• Gearbox AUMA GK25.2 (manual operation)

According to customer requirements, the cast Gate Valve S38 can be supplemented with a bypass valve. For bypass we recommend using our Globe Valve V46.2.
