Product Description

Product Description

Our Pressure Reducing Valve delivers precise pressure regulation for water, gas, steam, and oil systems. It automatically reduces upstream high pressure to a stable, adjustable downstream pressure (0.5-40 bar), protecting equipment and pipelines from overpressure.

Constructed from industrial-grade materials (brass, stainless steel, cast iron), it features a durable diaphragm/piston mechanism for leak-proof, long-lasting operation. Compatible with threaded or flanged connections, it suits HVAC, plumbing, industrial, and gas applications.

With self-acting operation, high precision (±0.1 bar), and compliance with ISO/CE standards, our PRV ensures reliable performance with minimal maintenance. OEM/ODM options are available for custom needs.

Product Advantages

Precise Pressure Control
Maintain a stable downstream pressure regardless of fluctuations in upstream pressure or flow, ensuring optimal performance of low-pressure equipment and systems.

Equipment Protection
Prevent damage to downstream components from excessive pressure, extending the lifespan of pipes, valves, pumps, and other machinery.

Energy Efficiency
Reduce unnecessary energy consumption by delivering only the required pressure, lowering operational costs in hydraulic, pneumatic, and water supply systems.

Versatility
Suitable for various media (water, gas, steam, oil) and applications, including industrial processes, commercial buildings, residential plumbing, and HVAC systems.

Self-Acting Operation
Many PRVs operate without external power sources, relying on fluid pressure for automatic adjustment, which simplifies installation and maintenance.

Customizability

Adjustable pressure ranges, materials (brass, stainless steel, cast iron), and connection types (threaded, flanged) to meet specific project requirements.

Safety Enhancement
Prevent overpressure-related hazards, ensuring a safe operating environment for both personnel and equipment.

Reduced Water Hammer
Mitigate pressure surges (water hammer) in piping systems, preventing noise, vibration, and potential pipe damage.

How does valve work?

Pressure reducing valve operates on a self-acting, feedback-driven principle to maintain stable downstream pressure. 

Here's its core working process:

First, the valve is pre-set to a desired downstream pressure. When fluid (water, gas, steam, etc.) flows through, the upstream high pressure acts on the valve's internal mechanism—typically a diaphragm or piston linked to the valve plug.
As downstream pressure rises to the set value, it pushes against the diaphragm/piston, compressing the internal spring and partially closing the valve plug. This restricts flow, preventing downstream pressure from exceeding the target.
Conversely, if downstream pressure drops (e.g., due to increased demand), the spring rebounds, opening the valve plug wider to allow more fluid through, thus restoring pressure to the set level.

No external power is required— the valve adjusts automatically in response to real-time changes in downstream pressure or upstream flow. This closed-loop feedback ensures consistent, precise pressure regulation, protecting downstream equipment and maintaining system efficiency.
