Difference between Gate valve and Globe Valve
A gate valve is often used to shut off the flow in the valve rather than regulate it. Because there are no obstructions in the flow path, this valve has a very low flow resistance. It prevents any kind of leaking. There are two positions for these valves: fully open and completely closed. When the gate valve is opened, the disc is completely removed from the flow stream. This valve provides a number of advantages over other valves. Gate valves are useful in a number of applications. They are used in the chemical, petrochemical, power generation, pulp & paper, and oil and gas refining industries.

- Non Rising stem Gate valve
- Bellow Sealed Gate valve
- Pressure Seal Gate valve
- Forged Gate valve
- Cryogenic Gate valve
A globe valve’s major purpose is to start, stop, and regulate the flow of the medium that passes through it. This kind of valve can be used for both isolation and throttling. During valve opening and closing, the disc in the valve rotates perpendicular to the seat. The flow is directed up through the seat ring against the disc’s bottom, making installation of a Globe valve simple. This stops dirt from flowing through the valve.
- Y Type Globe Valve
- Angle Globe Valve
- Bellow Sealed Globe Valve
- Z Type Globe Valve
- Pressure seal Globe Valve
Difference Between Gate valve and Globe Valve:
- Gate valves are normally not used for throttling where globe valve has better throttling capacity.
- Gate valves are mostly suitable for isolation where Globe Valve is suitable for regulating the flow of the medium.
- Gate valves has tight shutoff capacity and globe valves cannot seal as tight as a Gate Valve.
- Gate valves has lower flow resistance and has a smaller pressure drop whereas Globe valve has high flow resistance and higher pressure drop.
- Gate valves are unidirectional and globe valves are not.

How does a Control Valve work?
What is a control valve?
It is a power-operated valve that controls the flow of steam, gas, oil, and water. A control valve adjusts the flow to various degrees between minimal flow and full capacity flow in response to a signal from a control device. A signal is sent from the controller to the control valve, which causes it to move and change the flow. There are two pieces to it: a valve and an actuator. Depending on the service condition and application, their valve bodies come in a variety of shapes and sizes.
All of these control valves are meant to keep critical variables like inertia, pressure, velocity, temperature, and others within the proper operating range. Internally, one of these Valves absorbs and causes oscillations that harm the process component, and interaction with other network loops causes disputes that affect the device parameters.
Sensors and transmitters collect information about the process vector and its relationship to any appropriate fixed point in order to reduce the influence of these load distortions. After that, a controller gathers the information and assesses what needs to be done to get the process back to where it will be if the charge is disrupted. When all of the estimating, contrast, and calculations are finished, the controller’s chosen strategy must have some type of end control function.
