Syntholine specialises in supplying vast range of valves and control solutions.
​Industrial valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. In an open valve, fluid flows in a direction from higher pressure to lower pressure. Valves are classified by how they are actuated; Manually, Pneumatic, Hydraulic, Solenoid or Motor.

Diaphragm valve, which controls flow by a movement of a diaphragm. Upstream pressure, downstream pressure, or an external source (e.g., pneumatic, hydraulic, etc.) can be used to change the position of the diaphragm
Check valve or non-return valve, allows the fluid to pass in one direction only.
​Ball valve, for on/off control without pressure drop, and ideal for quick shut-off, since a 90° turn offers complete shut-off angle, compared to multiple turns required on most manual valves.
Butterfly valve, for flow regulation in large pipe diameters.
Gate valve, mainly for on/off control, with low pressure drop.
Globe valve, good for regulating flow.
Knife valve, similar to a gate valve, but usually more compact. Often used for slurries or powders on/off control.
Needle valve for accurate flow control.
Pinch valve, for slurry flow regulation and control.
Plug valve, slim valve for on/off control but with some pressure drop.
