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.
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
Double eccentric butterfly valve
Type ROCO wave (ERHARD)
Pressure: '10 / 16 / 25 / 40
Nominal size: 150 - 1600
The double eccentric butterfly valve ROCO wave is designed for water applications.
The valve is characterised by high energy efficiency, a flow-optimised design, minimal pressure losses and continuous corrosion protection.
The connection between the shaft and valve disc is covered by a polygon connection.
The double eccentric butterfly valve has a modular actuator concept through the use of a handwheel, electric actuator, stem extension, weight-loaded hydraulic actuator, pneumatic actuator or chainwheel.
PTFE lined butterfly valve
Type Typ CST economyLine (ChemValve-Schmid)
Pressure: 10 (16)
Nominal size: 25 - 1200
The ChemValve-Schmid butterfly valve CST is the world’s leading modular PTFE lined butterfly valve.
The PTFE lined valve is produced to the highest quality standards for the safe handling of aggressive media. It is designed for the use with highly chemical media and is therefore used in almost all industries.
Spherical structural elements reduce friction and therefore increase the service life.
