INDIUM PHOSPHIDE (InP) WAFERS are semiconductor materials made of indium phosphide, a compound semiconductor that is widely used in high-frequency and optoelectronic applications. Due to its efficient electron mobility and direct bandgap properties, InP is favored for devices such as:

High-speed electronics
Laser diodes
Photodetectors
Telecommunications applications, including optical fiber communication
We offer the following InP Wafers:
Undoped InP Wafers: These are pure InP with no intentional doping, used in various applications where intrinsic properties are required.
N-type InP Wafers: Doped with donor impurities (such as tellurium) to increase electron concentration, useful in transistors and high-speed electronics.
P-type InP Wafers: Doped with acceptor impurities (such as zinc) to create holes in the semiconductor, used in light-emitting devices and other optoelectronics.
InP Substrates: Used as a base for growing other semiconductor materials in heterostructures for various applications.
InP Membrane Wafers: Thin layers of InP used for specific applications, including applications in flexible electronics and advanced photonic devices.
InP-based Quantum Dot Wafers: Engineered to create quantum dots that can be used in photonic and optoelectronic devices for enhanced performance.

Plug valve is Quarter-turn rotary motion Valve that uses a tapered or cylindrical plug to stop or start the flow. The disk is in plug shape, which has a passage to pass the flow. In open position, this bored passage is in line with the flow. When the plug is turned 90 from the open position, the solid part of the plug blocks the flow.

Plug valve is used in place of gate valve where a quick operation is required. It can be used in high-pressure temperature services. On the other hand are the non-lubricated plugs which are generally used in places which requires zero maintenance. Apart from this, the threaded plug valves are used for flow control and prevention of contamination.

Plug valves generally have cylindrical and conical tapered installed. These tapered plugs rotate within the valve which controls the flow inside the valve. It also has of hollow passageways which permit the water to flow when the valve is open.

Ventura manufactures high mast lighting poles based on PLG 07 with complete raising and lowering systems in latching and non latching options. Our High Mast Lighting poles are regularly exported to countries such as UK, Qatar, UAE, etc. and are also installed regularly in India.
