SV3-PRV linear pressure reducing valve – Smart pressure control solution for water supply networks

In current water supply systems, maintaining stable pressure is always an important problem to ensure safe operation, reduce water loss, and increase pipeline lifespan. When pressure fluctuations within the network are not well-controlled, the risks of leakage, pipe bursts, and negative impacts on water supply quality are substantial. From that practical need, Saigon Valve has researched and developed the SV3-PRV linear pressure reducing valve as a modern, flexible pressure regulation solution suitable for smart water supply networks.

What is the SV3-PRV linear pressure reducing valve?

SV3-PRV is a line of linear pressure reducing valves that allows continuous adjustment of the outlet pressure according to control signals, instead of only operating at a few fixed pressure levels like traditional pressure reducing valve lines. Thanks to this, the system can react more flexibly to practical fluctuations in the network, helping to maintain stable pressure at many different operational times.

The product includes a pressure reducing valve, a control cabinet connected to the valve, and remote monitoring and control software. This model helps the operating unit not only simply reduce pressure but also monitor data, change target pressure values, and manage the system conveniently via a web platform. According to the catalogue content, this is a solution developed by the technical team of Saigon Valve Co., Ltd. and has been trusted and used by many partners.

Outstanding benefits of the linear pressure reducing valve

The outstanding strength of the SV3-PRV lies in its ability to proactively control pressure inside the pipeline, thereby helping to minimize leakage or pipe bursts during the water supply process. Effective pressure control not only protects the infrastructure but also contributes to reducing water loss and optimizing operational costs for the management unit.

In addition, the valve also has many notable technical advantages such as:

Proactive and accurate pressure control,
Stable operation even when the flow rate is close to zero,
Easy adjustment and maintenance,
The valve body is coated with high-temperature epoxy paint to increase durability during use.

Main technical specifications

According to the catalogue, the SV3-PRV linear pressure reducing valve has the following main technical specifications:

Connection standard: EN1092-2
Working pressure: PN16 / PN25 / CL150
Size: DN50 to DN300
Working temperature: 0°C to 80°C
Working medium: clean water
Pressure reduction range:
- PN16: 0.08 – 1.2 MPa
- PN25: 0.1 – 1.6 MPa

These specifications show that the product is suitable for many different scales of water supply systems, from medium pipelines to operational areas requiring precise and continuous pressure control.

Control cabinet – the operational center of the system

One of the important components of the SV3-PRV is the pressure reducing valve control cabinet, which plays the role of processing and coordinating operational signals. According to the description in the documentation, the control cabinet includes main parts such as:

mechanical pressure gauge,
pressure sensor,
pressure reducing pilot,
air pump,
solenoid valve assembly,
SV3-PRV controller,
power supply or battery.

The combination of these parts allows the system to adjust the outlet pressure in real time, while supporting more flexible operation compared to traditional mechanical valve models. The installation description diagram in the catalogue also shows that the valve and control cabinet can be practically deployed on existing pipelines, suitable for both new installations and upgrades.

Remote control via web platform

A very notable advantage of the SV3-PRV is the ability to monitor and control the valve remotely through the web. The software developed by SG-VAL allows:

real-time data monitoring via the IoT system,
tracking pressure, valve status, and operational parameters,
flexibly adjusting outlet pressure from safari / remotely,
scheduling pressure changes according to operational time slots,
expanding and integrating with SCADA or water network management systems,
periodic technical support and software updates.

This point is highly suitable for the digitization trend of the water supply industry, where operating units increasingly need solutions capable of centralized monitoring, fast alerts, and flexible control without having to perform manual operations on-site.

2026 Software Upgrade – enhancing monitoring and optimizing operation

According to the documentation content, the 2026 software version is upgraded with many new features to enhance the efficiency of pressure control in the water supply network. Some prominent features include:

system management map and visual incident tracking on the web platform,
valve control according to the critical point pressure in the DMA,
automatic adjustment of valve opening to maintain minimum pressure at the end of the source,
alerts and automatic pressure boosting when the pressure at the logger in the DMA drops below the set threshold,
user permission assignment according to each operational level,
visualization of operational data using charts and support for quick export via Excel.

In addition, the documentation also emphasizes three major improvement directions of the software, including friendlier UI/UX, better security, and faster processing performance, helping to reduce system lag or freezing during use.

Practical application in water supply networks

Regarding the operating principle, the catalogue describes that when the pressure downstream of the valve drops lower than the set pressure, the valve will automatically open to maintain an appropriate pressure level for the system. This mechanism helps the network always maintain a stable operational state, especially in end-of-source areas or DMAs where pressure fluctuates over time.

The network schematic diagram in the documentation shows that the SV3-PRV is not just an independent mechanical device but also part of an integrated pressure management solution, connecting field equipment, data collection systems, and the central control platform. This is a very suitable deployment direction for water supply units wishing to step-by-step build a smart network.

Installation and upgrade services from Saigonvalve

The catalogue also provides actual installation photos of the SV3-PRV linear pressure reducing valve in many areas such as Hue, Quang Ninh, and Ho Chi Minh City, showing that the product has been applied in the field rather than just stopping at a technical introduction. Besides new installations, Saigon Valve also offers an upgrade service for pressure reducing valves based on the old valve bodies that customers are currently using, thereby helping to save investment costs and utilize existing systems. The technical team will conduct field surveys, grasp demands, and propose appropriate upgrade plans.

Quality commitment from Saigon Valve

In the documentation, Saigon Valve emphasizes that quality is not just a commitment but a guiding principle throughout the entire operational process. The enterprise's management and production systems have been standardized and granted ISO 9001:2015 certification, demonstrating a serious investment direction into product quality and processes.

CONCLUSION

With the ability to continuously adjust outlet pressure, monitor and control remotely via a web platform, along with the capability to integrate IoT and SCADA, the SV3-PRV linear pressure reducing valve is a notable solution for modern water supply systems. Not only helping to control pressure accurately, the product also supports reducing water loss, enhancing network safety, and creating a foundation for the digitization of operational management. With practical deployment experience and accompanying survey, installation, and upgrade services, Saigonvalve is demonstrating its role as a provider of smart pressure regulation solutions suitable for many water supply projects in Vietnam.
