Metal seated butterfly valve for oil & gas applications
Type Typ MTV / MTVG / MTVL (Somas)
Pressure: 25
Nominal size: 80-500
“Somas valves type MTV, MTVG and MTVL are on/off valves and control valves that have been specially developed for oil and gas applications and are designed to control over a wide temperature range.
They are normally supplied with a metal seat.
They are all triple eccentric valves and due to the unique design of the valve disc, a solid stainless steel seat can be used. This solid seat is resistant to high flow velocities and temperatures. This allows us to achieve high functional reliability even in difficult applications.
The MTV valve can be supplied as a wafer type or lug type valve.
The valve type MTVG is a wafer valve with 4 guide bores.”
Metal seated butterfly valve
Type VSS / VSSL (Somas)
Pressure: 25
Nominal size: 80-1200
“The Somas metal seated butterfly / shut-off and control valve type VSS is suitable for controlling and shutting off liquids, steam and gases over a wide temperature range.
The triple eccentric design allows the use of a solid stainless steel seat due to the special contour of the disc. The disc geometry and the shape of the seat provide excellent tightness.
The seat is resistant to high flow velocities and ensures good tightness, even under difficult operating conditions. The seat, which is available in different materials, can be replaced.
The VSS valve was developed as a wafer valve and can also be supplied as a lug type valve (with threaded bores).”
