Metal seated butterfly valve
Type MTV / MTVF / MTVL (Somas)
Pressure: 25
Nominal size: 80-500
Somas shut-off valves type MTV, MTVF and MTVL are on/off valves and control valves.
These valves are designed to control many different liquids, gases and steam over a wide temperature range.
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 MTVF is a double flanged valve. They are normally supplied with a metal seat.
Plastic butterfly valve
Type EXTREME series (CEPEX)
Pressure: '6 / 10
Nominal size: 50 - 300
The CEPEX plastic butterfly valves can be used to shut off and control liquids.
The valves made entirely of plastic have the advantage that they are resistant to chemicals. The EXTREME series is designed for special requirements and can therefore be used in steel plants, chemical plants or the oil industry.
The plastic butterfly valve can be operated either manually or also automatically and is available in a wide variety of plastics (PVC-U, CPVC, PP-H, PVDF and ABS).
On/off and quick-closing butterfly valve
Type AK / SSK (Herberholz)
Pressure: 6-10bar
Nominal size: DN50 - DN400
The butterfly valve is designed for all flammable gases according to EN437 and other neutral gases.
The safety shut-off butterfly valve was developed according to EN161 A (closing time <1 s), approval according to DIN EN IEC 61511, up to and including SIL3.
It consists of a one-piece housing, seals tightly and has a centric valve disc and a leak-proof shaft.
For clamping between flanges according to DIN EN1092-1, length according to DIN EN 558-1-R20.
Leakage rate A according to DIN EN 12266-1, maximum permissible operating pressure 10 bar, from DN350 <1.5 bar
On/off and control butterfly valves
Type HRD / HRA (Herberholz)
Pressure: max. 2bar
Nominal size: DN15 - DN1200
The throttle valves HRD and HRA are designed as a wafer type valve with a centric valve disc.
Depending on the choice of material, they are designed for operating temperatures up to 1050°C. In the high-temperature version, they have a welded wafer type housing or a one-piece housing.
The throttle valves are suitable for valves according to DIN EN 1092-1 or ASME B16.5 / ASME B16.47, with lengths according to DIN EN 558-1-R20, as well as from DN400 according to the company standard.
The connecting flange is for actuators according to DIN EN ISO 5211.
Testing according to DIN EN 12266.
SIL approval according to ICE 61508 and ICE 61511
