Different Types of Valves Used in Pipelines

A valve is simply a device that directs or modulates flow by opening, closing or partially blocking passageways. Below are some of the kinds of valves and their applications.

  • Gate Valves

Gate valves are valves which open by lifting out a gate of the route of the fluid. Gate valves are intended to be completely open or closed; they are regularly used as a block valve for isolating pipe systems.

When a gate valve is open, there is no obstruction in the Flow path leading to very little friction reduction. To know more about gate valves Visit Website on http://www.asia-pacifics.com/products_list/134.

  • Globe Valves

Instead of having the “all or nothing” function of a gate valve, Globe valves regulate by the position of a movable disk (or plug) compared with the stationary ring seat.

A globe valve may be pointed at an angle. This type of Angled supply valve is commonly used for corrosive or thick, viscous fluids that tend to solidify.

  • Needle Valves

The needle valve is essentially a version of the Planet Needle valves contain a slim, tapered plug, as opposed to the globe valve’s larger and less precise disk.

  • Butterfly Valve

The butterfly valve is also designed to regulate flow, but with limited control capacity. This is a simpler industrial valve and fitting that’s easily operated by rotating a handle 90 degrees.

  • Check Valves

Check valves, also known as NRVs (non-return valves), permit fluid to flow in one direction only. Their purpose is to prevent backflow. There are several types of “stoppers” that prevent backflow in check valves. Ball check valves and piston check valves function by requiring a minimum amount of inbound flow pressure; backflow is not strong enough to lift the ball or piston back up to travel the other direction.

  • Relief Valves

The relief valve, also known as the safety valve, is an Industrial valve and fitting installed to set a limit on the quantity of pressure in a system. This type of angled supply valve is strictly for preventing Over-pressure that could cause damage to the system.
