What is a CRD valve?

The CRD senses downstream pressure directly and the CRA senses downstream pressure remotely. These valves are ideal small capacity regulators for applications such as water coolers, fountains, humidifiers, gas refrigerators, and air supply to tools and instruments.

Can you clean out a pressure reducing valve?

These mineral deposits accumulate inside of the valve body, leading to lower-than-intended home water pressure. In most cases, a plumber can resolve this issue by disassembling and cleaning out your regulator valve. Soaking the valve in a calcium and lime remover loosens up and dissolves unwanted mineral deposits.
