Sunaina Engineering Industries - VALVES

Control Valves are used to combine two flows or to divert one flow into two outlets. They are designed to replace and perform the functions of two single ported control valves acting in opposite directions, in converging or diverging liquid flow. They can beused to control the circulation of water, oil, sea water or other liquid in heating or cooling applications involving heat exchanger bypass control. They can also be used in blending systems and on-off selector systems.

Types of valves

• 2 Way Control Valve     
• 3 way Control Valve
• Angle Type Control Valve

Size : 15 NB  to 300 NB 

Dome Valve is a pressure tight compressed air operated valve for handling abrasive, material & slurry mixture without wear & tear. Simple in design & low maintenance. This valve is used in pneumatic conveying systems in different Industries. It is provide positive closure between hoppers and blow tanks. They are capable for cut off moving and satiric column of powder pastes & up to 40 mm particle size. Pressure tight closure is provided by either eccentric shape of the dome and with help of an inflatable seal to prevent leakage. They provides the pressure tight seal against the dome surface when in the closed Position.

Guillotine Damper are most commonly specified when isolation is the primary function of the damper. Guillotine dampers are best-suited for isolation applications where low leakage and pressure drop are important Guillotine dampers and blanking plates can be used in any application where a positive isolation is required for routine maintenance and entry to a duct behind a media source. Guillotines are classified in two styles - Low Leak and Zero Leak. Both styles are ideal for a high degree of isolation while providing low pressure drop when the dampers are in the open position. The basic mechanical elements of the guillotine damper are a blade, a peripheral - seal system to prevent gas leakage at all stages of blade movement, support members for the blade, and a drive to move the blade steadily and continuously from open to closed and back again.

SEI" Double Disc valves were designed to for on/off service in venting and conveying lines on high pressure pneumatic conveying applications. The design is rugged and clean operating. The Double disc valve ha metal to metal sealing to reduce wear in venting and discharge applications. The internal linkage drives the two spring loaded disks against the lapped body endplates. The disks move along a unique path and rotates with each stoke of the air cylinder which distributes the wear evenly and extends the life of the disks and endplates. "SEI" Double.

More About Information for

• Gate Valve : The most common and traditional type of valve is a gate valve. The Gate Valves are large to accommodate the yoke and stem mechanism, but fully open the full bore design provides an uninterrupted flow path. Generally either used fully open or closed, for on/off isolation.
