Z-Tide Co Ltd

valves that release trapped air and vacuum

Check + non return valves only allow flow in one direction

Filters designed to remove particulate or debris from gases or fluids.

Air control valves operate with a manual lever. 3/2, 5/2, 5/3, 4/2 + 4/3 way

Pressure reducing valves (PRV) reduce and maintain stable outlet pressure

Safety pressure relief / pressure limiting valve (PLV), stays closed until pressure reaches set pressure - then quickly opens, releasing any excess pressure.

Pressure sustaining / back pressure valve, maintains a minimum preset upstream (Inlet) pressure, valve will close if pressure drops to set pressure and reopens when inlet pressure increases again.

Valves controlled by electrical signal via a solenoid or electro magnet.

Water hammer arrestors designed to absorb and remove water hammer banging, thumping, clanking and rattling caused by water hammer shock waves.

Directly controls flow without external pressure assistance operates from vacuum upwards.

Operate via pilot pressure control and require a minimum pressure difference between inlet and outlet from 0.5 Bar.

Prevents or reduces water hammer caused by sudden changes in fast moving fluid flow.

Valves that require manual input to operate such as lever, button or switch

A facility to manually move the valve into the fully actuated position via a button, lever or key.

Supplied with additional threaded holes typically in the base, typically for securing to a baseplate.
