Kuhnway Corporation (Queen)

Motor and air actuated quarter turn 2+3 way ball valves

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.

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

The valve is equipped with an additional volt free electrical switch that is triggered when the valve is mechanically closed.

The valve is equipped with two additional volt free electrical switches that are triggered when the valve is mechanically closed or open position.

The valve is equipped with clear cover or dome under which an arrow or flag can be seen to confirm either the open and or closed position of the valve.

The copper shading ring in the solenoid tube has been replaced with silver. Typically used for RO water and aggressive media applications.
