Syntholine specialises in supplying  valves and control solutions.
​Industrial valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidised 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

Non-Return Check Valve

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.
