Válvulas de retención para contadores de agua serie OV
Water meter check valves are used in inlets, outlets, connectors and fittings or piping systems to prevent backflow of water through the meter. These plastic check valves, also known as one-way globe valves or check valves.
Application :
Water meter check valves are used in inlets, outlets, connectors and fittings or piping systems to prevent backflow of water through the meter. These plastic check valves, also known as one-way globe valves or check valves, serve several important functions, including:
Prevent back flow:
The meter check valve ensures that water flows in only one direction, thus preventing backflow. Backflow can occur when the pressure on the downstream side of the system becomes greater than the pressure at the source. This can contaminate the water supply or cause damage to the plumbing system.
Water meter accuracy:
The check valve helps maintain accurate water consumption measurements by preventing the meter from rotating backwards. Without a check valve, water can backflow through the meter, resulting in inaccurate measurements and potentially billing discrepancies.
Prevent pressure fluctuations:
Check valves prevent pressure fluctuations or water hammering. Water hammering can occur when there is a sudden change in pressure within a piping system, such as when a valve closes quickly. Check valves help reduce the effects of these pressure fluctuations and prevent damage to the piping system.
System isolation:
The check valve allows isolation of the water meter from the associated piping system. This can be done for maintenance or repairs without shutting off the water supply to the entire building. By closing the check valve, the water meter and downstream pipe can be isolated while performing work.
Overall, water meter check valves play a vital role in maintaining the integrity of the water supply system, ensuring accurate metering, preventing backflow, and facilitating maintenance and repair.
Characteristics and advantages
Water meter check valves have several key characteristics that make them effective and reliable
For its intended applications:
1. One-way flow:
These valves are designed so that water can only flow in one direction. They work by making sure the water passes through the meter in the correct direction as the water tries to flow in the opposite direction.
2. Spring loading mechanism:
Water meter check valves usually employ spring-loaded mechanisms when there is no forward flow. The spring ensures seal and prevents any leakage or backflow.
3. Low pressure loss:
Check valves are designed with minimal flow resistance. They have streamlined channels that minimize pressure drop and allow efficient water flow through the system.
4. Compact design:
Water meter check valves are compact and suitable for installation in confined Spaces. Their compact design also ensures that they can be easily integrated into piping systems without causing significant interference.
5. Corrosion resistance:
The OV series check valves are made of PVC and offer excellent corrosion resistance. This ensures their longevity and reliability even in environments with high moisture or chemical exposure.
6. Easy to maintain:
Water meter check valves are generally easy to maintain. They can be easily checked and cleaned if necessary. Some models may also have removable covers or access points for repairs or repairs.
7. Compliance with standards:
Quality check valves comply with various industry standards and regulations to ensure their performance and reliability. Common standards include those developed by organizations such as NSF International (NSF/ANSI 61) and the American Water Association (AWWA C508).
Together, these characteristics contribute to the availability and reliability of water
Instrument check valves ensure accurate measurements, prevent backflow, and maintain the integrity of the water supply system.
