Measure Monitor Control is an independent specialist distributor of valve and instrument solutions. We are dedicated to providing high quality innovative solutions working with a global supply chain to provide the ideal specification for the client, on time and on budget.

Pressure reducing valves (PRV), also know as pressure regulating valves, lower the downstream pressure to match the setpoint, opening as the pressure falls and closing as it rises. These mechanical valves employ a spring against a diaphragm or piston as the control element which makes them simple and reliable in operation. The use of larger diaphragm sizes provides increased sensitivity for lower pressure ranges in the more specialised models. View our selection of pressure reducing valves (PRVs) below.

3. If pressure on the inlet side starts to exceed the outlet side, it overcomes the preset spring tension and forces the diaphragm to move up, closing the valve.

2. Water can flow through the valve if upstream pressure remains at or below the set level of downstream pressure. At these times, there will not be enough pressure to force the diaphragm upward, which would subsequently close off the valve.

Our range of PRV's provide control under both dynamic and static flow conditions, providing flexibility depending on application. All of our PRV's meet the relevant European and UK safety requirements.

Sometimes referred to as a pressure regulator, as opposed to a pressure reducer, the valve uses spring pressure against a diaphragm to control the valves position.

Pressure Reducing Valves (PRVs) ensure that an appropriate and comfortable liquid usage pressure is available at all times. These valves enable the control of pressure from boosted supplies, to match application requirements and ensure components installed downstream of the PRV aren't exposed to high pressure, which could result in damage.

1. The required outlet pressure is set using a dial on top of the valve. Turning this dial adjusts the tension on the internal compression spring, which holds the diaphragm in place.

4. Demand on the outlet side typically results in low pressure (often referred to as fall-off pressure), which allows the valve to remain open. This is an example of dynamic pressure control. On the other hand, back pressure from downstream can result in the valve remaining shut, an example of static pressure control.

Mixing valves are designed to blend hot water with cold water to ensure a constant, safe outlet temperature. They are utilized in residential, commercial, and institutional applications where controlling water temperature is critical to avoid scalding, thermal shock, and Legionella growth.
