Valves are an essential part of any piping system, which means they play a key role in the oil and gas industry. They can be used to control flow, isolate and protect equipment, and guide and direct the refining process of crude oil.
1. Control valve
Control valves are valves that provide process control of flow, pressure and temperature in the oil and gas industry. They work by changing the size of the flow passages as directed by hydraulic, pneumatic or electrical signals sent by the controller. The automatic operation of these valves allows them to be operated remotely, rather than having operators constantly monitor and adjust.
2. Butterfly valve
Butterfly valves are used to isolate and regulate various media with low pressure loss. Valves are usually equipped with actuators. Their small thickness allows them to be installed almost anywhere, while their ease of use in larger diameters means they can be used in larger pipes. When activated, they open and close quickly, provide high reliability and require little maintenance.
3. Ball valve
Ball valves are designed to control the flow of high pressure liquids and gases with minimal pressure drop. They open and close quickly and have a tight seal with low torque. Their ease of operation, maintenance and versatility allow them to be used in a variety of positions.
4. Check valve
Check valves are used to prevent reverse flow through the pipeline. Their services help protect pumps and equipment that could be damaged by backflow, reducing system maintenance and downtime. These valves have a low pressure drop, which increases energy savings. They also help reduce chatter within the pipe.
5. Globe valve
Globe valves are commonly used in isolation and throttling services. Installation is simple as the seat is easy to machine. They provide a tight shut-off capability and a simple linear motion allows quick opening and closing of the valve.
