Applications and Uses
Valvetech distributes a wide variety of Cast Steel valves, Cast Steel Gate, Cast Steel Globe, and Cast Steel Check Valves in Dubai. Our cast-steel gate, globe, and check valves surpass all industry performance necessities. These cast steel valves are ideal for the downstream market. The gates, globes, and checks all possess raised-flange, ring-type joint, and butt-weld ends as connection options.
Valvetech valves features leading-edge design, engineering, and manufacturing technology. Our valves meet the most stringent national and international standards for fugitive emissions.
Our gate, globe, and check valves are widely used in many industries including: Upstream and midstream industries: Offshore production platforms, ship-building; Process industries: oil, chemical, petrochemical, refining, pharmaceutical, mining, water treatment; Power industries: nuclear plants, renewable and district heating.
Gate valves are used as shut off valves in many industries. They are beneficial when minimum pressure drop and bi-directional shut off service is required. Commonly used in industrial piping for stop or isolating to turn on and shut off the flow as opposed to regulating flow. Gate valves are named from the gate-like disc which operates at a right angle to the path of the flow. Gate valves are general service valves that can be made in a broad spectrum of sizes using a variety of different materials.
Globe valve is named after is globular body. Compared to gate valves, globe valves are designed to open and close more quickly. Their flow characteristics can be changed by re-configuring their discs. The flow path through globe valves follows a changing course, thereby causing increased resistance to flow and considerable pressure drop. Because of the seating arrangements, globe valves are the most suitable for throttling flow, however avoid extremely close throttling when the repeatable pressure drop exceeds
Sometimes referred to as a non-return valve, the check valve prevents back-flow in the piping by constantly keeping fluid flowing in one direction. Check valves operate automatically. Some
piston/disc check valves are spring loaded for fast operation, (minimum cracking pressure should be specified). Vertical downwards flow requires a spring loaded check valve.
