What is a pressure reducing valve?

A pressure reducing valve is a device used to lower the pressure in a water system. This valve is installed in the water supply line and reduces the incoming pressure to a safe level for the system components. This helps prevent damage to the system components such as pipes, valves, faucets, etc.

How does a pressure reducing valve improve water system efficiency?

Installing a pressure reducing valve in a water system enhances system efficiency in several ways. Firstly, it reduces the risk of damage to system components, thereby lowering repair and maintenance costs.

Additionally, the pressure reducing valve helps save water by reducing the flow through the system. This means that less water is used to achieve the same results, which helps reduce water costs.

There is also an improvement in energy efficiency. The pressure reducing valve lowers the incoming pressure, meaning that the system’s motors and pumps need to work less to achieve the same results. This means less energy is used to achieve the same results, helping to reduce energy costs.

What to consider when installing a pressure reducing valve

It’s important to consider several factors when installing a pressure reducing valve. Firstly, ensure that the valve is installed correctly. This means it must be installed in the correct water supply line and must be the appropriate size for the system.

Additionally, it is crucial to ensure the valve is properly adjusted. This means that the valve must be adjusted to reduce the incoming pressure to a safe level for the system components. If the valve is incorrectly adjusted, it can cause damage to the system components.

How to maintain a pressure reducing valve

Maintaining a pressure reducing valve is crucial to ensure it functions correctly. This includes periodic inspections to check for leaks or damage. It is also important to ensure the valve is properly adjusted to maintain safe incoming pressure for the system components.

How do users benefit from installing these valves?

Users benefit from installing a pressure reducing valve in several ways. Here are the key benefits:

  • Reducing system and component failures.
  • Helping to reduce energy usage.
  • Helping to reduce excessive water consumption.
  • Ensuring the safety of the installation.
  • Maintaining adequate pressure.

Additionally, the installation of a pressure reducing valve may be mandatory in some buildings and properties, making it necessary to comply with certain regulations.

Leopard pressure reducing valve

The leopard diaphragm-operated hydraulic pressure reducing valve is an essential component in water systems where pressure reduction is required. This valve operates via a pilot that adjusts the downstream pressure to maintain it at the desired regulation value. It is recommended for protecting installations and adjusting pressure to consumption needs.

The leopard pressure reducing valve range covers sizes from dn 20 to dn 300, and its operation is quite straightforward. The pilot sets the downstream pressure regardless of the incoming pressure and only acts when the downstream pressure exceeds the set pressure.

To adjust the pressure, the appropriate pressure reducing pilot must be selected, and the screw must be turned clockwise or counterclockwise to decrease or increase the downstream pressure, respectively. It is important to note that the maximum reduction ratio is the incoming pressure multiplied by 1/3, meaning that for an incoming pressure of 6 bar, the maximum output pressure would be 2 bar. If the incoming pressure is below 2 bar, the hydraulic valve could suffer from cavitation problems.

The valve’s precision ratio is ±0.3 bar, ensuring precise pressure regulation. In summary, the leopard diaphragm-operated hydraulic valve is an excellent choice for improving water system efficiency by reducing pressure where necessary and protecting installations.
