Advantages of Metal Seated Valves:

The key advantage of metal seated valves when compared to soft seated valves is that they can withstand high temperatures and severe service conditions.

Metal seats can stand up to extreme flashing, hydraulic shock, abrasive process fluid, and high temperatures. They are also ideal for high erosion or corrosion applications.

Another important factor is that metal seats can be hardened by specialized coatings.

Design:

1. Top flange design as per ISO 5211, optional actuators of gearbox, electric actuator and pneumatic actuator are available.
2. Hard faced ball and the seat to satisfy the requirement of high hardness, high temperature resistance, wear resistance.
3. With the help of the pre-loaded spring, the seat can maintain seal even in low operating pressure.
4. Several designs of the seat to choose from, among which the dust proof seat design is available.
