Gate Valve

Gate Valves are used extensively throughout the Refineries,Hydrocarbon,Energy and process industries. Size: 2" up to 88" (DN 50 up to DN 2200) Pressure Rating: ASME 150# to 2500# Materials: Carbon Steels, Low Temperature Carbon Steel, Martensitic Steels, Austenitic Stainless Steel, Duplex Stainless Steels, Super Duplex Stainless Steels, Nickel Alloys, Nickel Aluminum Bronze, Hastelloy, Inconel, Titanium Alloy & Carbon Steel with Internal Corrosion Resistant Alloy (CRA) Overlay Design Standard: API 600,BS 1414,API 6D Pressure / Temperature Rating: ASME B 16.34 Test (Inspection) Standard: API 598, API 6D, ISO 5208, API6FA, ISO 10497,BS6364 Construction Details: Bolted Bonnet / Pressure Seal Bonnet, OS & Y Type Rising Stem End Connection: Flanged,Butt-Weld Operator / Actuator: Handwheel,Gear,Actuator (Pneumatic, Hydraulic, Electro-Hydraulic and Electric Motorised) Cryogenic Service: Gate Valves can be designed in a special version suitable for cryogenic service. In this case, all the materials and technical features are designed to withstand minimum design temperature required by the Customer, down to Cryogenic -196C. If required by the customer, specific Cryogenic Tests are performed to verify the behaviour of production valves in terms of valve torque, sealing capability, emissions vs the ambient.

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve. A gate valve can be defined as a type of valve that used a gate or wedge type disk and the disk moves perpendicular to flow to start or stop the fluid flow in piping. A gate valve is the most common type of valve that used in any process plant. It is a linear motion valve used to start or stop fluid flow. Therefore, there is little pressure drop or flow restriction through the valve. Gate valves are used in many industrial applications including the oil and gas industry, pharmaceuticals, manufacturing, automotive, and marine. Gate valves are not suitable for throttling purposes.

The operation of the gate valve has got it its name. This valve acts like a gate to stop or allow the flow through itself. The valve is either fully closed or fully opened, thus, it faces least pressure drop. These valves are designed for uses related to liquid and gases flow. Here, the valve is opened by lifting the wedge out of the flow path. They are best suitable for hot tapping and pigging and not for throttling purpose.
