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.

METAL SEATED VALVE
1. Metal Seated Valve in case of Triple Offset Butterfly Type has superior
sealing structure by using the metal seat of laminate or solid which is
combined with valve BODY or DISC.
2. Disc can be operated without jamming in high temperature &pressure.
Available for Wafer, Lug , Flange type.
3. Owing to coating valve body & disc with stellite or special material ,
using this valve is adequate for the extremely inferior line of dust or
sludge i.e.semipermanent structure of this valve needs not exchange of
seat.

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

The self-centering disc
The construction guarantees the optimal position of the laminated seal against the seat. Jamming due to thermal expansion is eliminated.
Torque transmission using keys
The disc is keyed to the shaft not pinned, providing balanced torque transmission and eliminating the danger of pins shearing off.
Ideal lamination and disc design
The strong disc with its eliptical supporting surface offers the best fixing of the lamination. Bubble tightness is given as a result of the special machining of the lamination.
Supporting bearing bushings
The optimal position of the bearing reduces the risk of the shaft bending. This guarantees bi-directional tightness at maximum differental pressure.
