A pressure reducer is designed for use in a liquid delivery system, which requires its liquid contents to be pressurized to a first, relatively high pressure but also requires that the liquid be delivered to a downstream location such as a faucet at a second, relatively low pressure. The pressure reducer reduces the pressure of the flowing liquid by repeatedly imparting directional changes to the liquid. It comprises a stationary restrictor having multiple aligned segments, each of which is configured to divide the liquid into two or more diverging streams and to recombine the streams at the end of the segment.

Pressure Reducing Fittings are used to provide a secondary reduced pressure to an actuator to control its operating force. The relieving function gives a safety feature regarding protection under external loads. This prevents unacceptable pressure build-up where high external loads are reflected on actuators.

Pressure Reducing Valves provide a steady pressure into a system that operates at a lower pressure than the supply system. The primary function of the pressure-reducing valve is to maintain a constant downstream pressure. Pressure reducing valves are used to reduce the pressure on the water line to prevent water pipe blowout.
