"An unbeatable valve for use in engine exhaust pipes" would be a good description of the butterfly valves and ball segment valves specially designed and developed for this purpose by SOMAS.
The most commonly used and best adapted valve is the butterfly valve . Its simple, robust and maintenance-free basic construction makes it the premier choice for exhaust gas valves. It can be further customized with shaft sealing and/or bearing bushings to further enhance its performance, depending on the engine and fuel used. The ball segment valve is an alternate choice.
Exhaust valves and actuators
Exhaust valves are shipped bundled with actuators and positioners. Most actuators have customized mounting as well as high temperature gaskets in both the actuator and positioner. The positioners are also adapted to withstand the engine vibrations.

Posi-flate's unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for a bubble-tight seal, every time. Because the seat makes only casual contact with the disc during valve opening and closing, there is minimal disc impingement. This is in contrast to conventional butterfly valves where disc impingement leads to shaving of the seat, decreasing the overall performance and valve life.
Substantially less torque is required to open and close the Posi-flate butterfly valve, thus a smaller actuator can be used resulting in lower overall valve cost.

Remote Control Valve:
Hayward's Pneumatically Actuated Diaphragm Valves are designed for the reliable, remote control of liquids in piping systems. They are suitable for both clean and slurry type fluids at pressures up to 150 PSI.
Position Indicator:
You never have to guess if a Hayward Diaphragm Valve is in the open or closed position. A visual position indicator comes standard with every valve.
Powerful Actuator:
The actuator used to operate the valve, while lightweight and compact, is still powerful enough to open and close the valve at all internal pressures up to the full rated pressure of the valve,150 PSI.
No Corrosion Problems:
Hayward's Diaphragm Valves stand up to the most aggressive fluids and they will never rust, corrode or contaminate the process fluid. Even the actuator housing is plastic and requires no failure prone coating or painting.
Modular Options:
Several modular design options are available. This concept is very cost effective because the actuator can be configured exactly for a specific application using only the options required. You never have to pay for options you do not need.

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.

1. FEATURES
The centerline of the cone is rotated away from the valve centerline
resulting in an ellipsoidal profile and providing the third offset.
With this geometry, seat seal interference is completely eliminated
ensuring long sealing life.
The triple offset is reasonably desinged to metal seated valves
providing bubble tight performance on high temperature, high pressure
and firesafe applications

Operating conditions encountered in the automatic controlling of gas and air flows often require valves with an adjustable flow curve which can be altered at various points of opening to obtain the desired amount of flow. With Hauck adjustable flow valves, the flow rate can be easily changed at any of the 10 or more adjusting points provided. Therefore, the valve flow curve can be characterized to suit different constants in pressure, flow suction, or discharge resistance occuring at the minimum, maximum or in-between capacities.

General description
Butterfly valves are the most efficient and reliable sealing Isolation valve mechanism under high vacuum working conditions. A vacuum seal provided around the plate periphery in the main body of the valve ensures fail proof working of the valve. For efficient working of the valve it is advised to ensure that the sealing plates are facing atmosphere.
Butterfly Valves are of small in terms of thickness which ensures easy and faster passage for air and gases and are ideally suited for "In-line" isolation purpose. Though the butterfly valve is not intended to be used as an independent valve, it is widely used as a Baffle Valve in union with a chevron baffle at the top of a Diffusion Pump. These Butterfly Valves are offered in stainless steel SS-304 non-magnetic AISI quality high carbon steel chromium plated construction and they can be manually or pneumatically operated as per customer choice.
