When ultra low profile is required we offer the SB Sanitary Butterfly Valve. Compliant with the USDA 3A requirements for manual cleaned butterfly valve for handling dry powders. The valve dismantles by hand in minutes for quick inspection and cleaning. Manufactured in the US from 316L Stainless Steel and FDA Silicone seals the valve is offered in #4 satin or #7 mirror polish with manual or air operators. Standard and engineered options such as weld necks and Tri-clamps are also offered. Many sizes are stocked or are available with short lead times.

SOMAS metal seated butterfly valves have as standard a seat made of solid stainless steel.
The unique design of disc and seat gives tight shut-off. As standard the butterfly valves meet the leakage class ANSI B.16.104 class V (Class VI for valves with PTFE-seat).
The metal seated butterfly valve has opened new opportunities for demanding applications. The design of the VSS- and MTV-valves in combination with choice of materials provides the widest possible range of applications for control as well as on-off.
The combination of low weight, short face to face dimension, simple operation and, above all, good tight shut-off make the valves an advantageous alternative for most control- and shut-off applications.
The universal design, enabling the valves to be manufactured in several different materials, broadens its field of application. The high velocity will have no effect on the metal seat and the valve will keep its tight shut-off ability for many years of operation.
The butterfly valve can be used for both clean and contaminated fluids, gases and vapours. For control installations the valve is fitted with SOMAS pneumatic actuator and positioner.
With dimensions up to DN 1200 and pressure classes PN 10-50 we are able to cope with most applications within the process industry.
