Butterfly Valves

 A common valve type used in large-diameter pipes. They are typically used for basic on/off service, but can also be effectively used to throttle flow. They are operated with a simple 90-degree turn (quarter-turn) of a disc-shaped obstructor. This disc has a slim profile around which flow passes when parallel to flow but stops the flow in the when rotated 90 degrees to fill the entire opening of the valve.

Globe Valves

When precise control is needed, globe valves are the favorite in many industries. Globe valves use linear motion of a plunger that seats in a seat in a plane that divides the upper and lower half of the valve. In 2-way globe valves, the lower half is connected to the inlet port, and the upper half is connected to the outlet. On 3-way globe valves, there is a third port directly below the seat.

Plug Valves

Plug valves have a cylindrical “plug” with a passage through it when turned allows fluid to flow through it.  They are great for fluid shutoff applications and are often more economical than other types of valves.

Gate Valves

Gate valves are a common valve type used for basic on/off service. Manual Gate Valves are operated with a simple hand wheel that causes the stem and gate to rise. When closed, the gate seats against a seat ring, both of which have a special treatment to provide reliable shut-off.
