Check Valve

Globe Valves are extensively used through-out the Refineries,Hydrocarbon,Energy and process & the power industries. Size: 2" up to 24" (DN 50 up to DN 600) 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: BS 1873, API 623 Pressure / Temperature Rating: ASME B 16.34 Test (Inspection) Standard: API 598,ISO 5208,BS 6364 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: Globe 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 -196'C. 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

Check valves are basically the type of valves which prevent the backflow of the fluid or gas traveling through that specific pipeline. The liquids or gases flowing through non-return valves flow in single direction mainly. These poppet check valves consist of two openings which mainly allows the fluid or gas to enter from one end and leave from the other end. If the flow turns and no check valve is installed, water hammer can occur. Water hammer often occurs with an extreme force and will easily damage a pipeline or components. Check valves are used in many different applications. For example they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps are not self-priming, and therefore check valves are essential for keeping water in the pipes. Also, check valves are very often used in HVAC-systems (Heating, Ventilating and Air Conditioning-systems).
