Butterfly Valve – double offset (soft seat)
Butterfly Valve – KKD-MS82
Double Offset Butterfly valves are well suited for applications where rubber lined butterfly valves cannot be used due to limited pressure and temperature range. These offer 100% bidirectional disc sealing with soft seats, while metal seat offers uni-directional sealing in high temperature applications. On request, the metal seat option can be made bi-directional to EN 12266-1 Class V.
A double offset butterfly valve has two offsets from the valve body’s center.
This creates a cam action of the disc in the seat, which reduces the torque required to operate the valve.
The double-offset butterfly valve is designed to be used in applications requiring greater resistance to the pressure.
In general, metal seats incorporate a metal-to-metal seal between the seats and ball of the valve assembly.
In general practice, 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.
