Compact Pressure Reducing Valve
Compact Pressure Reducing Valve
The Compact Pressure Reducing Valve integrates four core functions: an adjustable pressure reducing valve, an isolation valve, a check valve, and a stainless steel filter screen. It is suitable for any installation position. And it can be directly connected to heating systems and domestic water pipelines. It automatically performs water filling and replenishing operations for pressure hot water heating systems. The built-in check valve can prevent hot water backflow from contaminating domestic water. The pressure-reducing filter element can be maintained without emptying the system.

1. How does a compact PRV differ from a standard pressure relief valve?
Compact pressure relief valves follow the same working principle as standard pressure relief valves. Both use spring preload and water pressure to drive the valve cartridge open and closed. The compact version is engineered for tight installation spaces, designed for small-diameter water supply pipelines with medium and low flow demand.
The main distinction between the two lies in physical size and operating conditions. Every internal part of the compact relief valve is miniaturized after structural optimization. Its overall volume is 20%–30% smaller than the standard model. It runs steadily at medium-low pressure (0.3 to 1.0 MPa) and handles normal pressure fluctuations in small pipelines. Standard pressure relief valves have larger internal bores, longer pressure-sensing elements, and split construction. They are built for high-pressure environments that require high flow capacity.
They also have different installation demands. Compact relief valves fit confined spots and allow multi-angle pipeline mounting. A threaded direct connection eliminates the need for additional fittings, such as mounting brackets and dedicated drain piping. Standard relief valves need extra clearance for safe pressure discharge.
2. Can the pressure-reducing valve spring be customized for non-standard requirements?
Yes, Plumberstar fully supports the customization of PRV springs for non-standard requirements. The specifications of the spring will affect the set pressure, pressure regulation range, and pressure relief response speed of the pressure-reducing valve.
For non-standard spring customization, we will first confirm your specific technical requirements. Then select the spring material. Available materials include 304/316 stainless steel, high-carbon spring steel for high-pressure industrial systems, and Inconel alloy for high-temperature special working conditions. And design the spring structural parameters through pressure performance tests. We can provide small-batch customized production for sample verification.
3. Is the pressure reducing valve 100% pressure tested?
Our 100% pressure testing is not a random sampling test, but a strict quality commitment implemented for every pressure-reducing valve. For all pressure reducing valves, after the assembly, polishing, and sealing processes are completed. We conduct a comprehensive pressure test on the finished products. Each valve is individually connected to automated pressure testing equipment. The test pressure is set to 1.5 times its rated working pressure and maintained for 3-5 minutes for strict inspection.
At the same time, the pressure test data of each pressure-reducing valve is collected. It is together with its unique product number that is recorded in our traceable quality management system. It can be queried and verified at any time.
4. How do your PRV burst pressure tests exceed industry standards?
Mainstream industry standards require that the burst pressure test for pressure-reducing valve bodies be at least 2.5 times the rated working pressure. It only requires the valve body to avoid rupture without specifying strict deformation limits. However, our standard increases the burst pressure test for all pressure-reducing valves to 4 times the rated PN. For custom pressure reducing valves used in special scenarios, we can even require the multiple to be further increased to 4.5–5.0 times the PN.
More importantly, we set very strict rules for deformation. After the burst pressure test, the valve body, valve seat, and pressure control chamber must not change shape permanently. Many industry standards only require that the valve does not break. Our rule is higher. This means the pressure-reducing valve can still keep its shape and work properly even if an accident happens, helping to avoid more damage to the pipeline.
In the industry, testing rules for compact pressure reducing valves are often looser. Because these valves are small and have thinner walls, some standards allow lower burst pressure or shorter test time. We do not do this. All our pressure-reducing valves follow the same strict burst pressure test.
5. Do you perform dezincification testing on pressure-reducing valves?
Yes, we conduct dezincification corrosion tests on all PRVs with brass valve bodies. The test standards include ISO 6509 and ASTM B753.
Incoming material dezincification test: For DZR brass raw materials and forged valve body blanks, we take sample pieces and run a standard dezincification test based on ISO 6509. The samples are soaked in a mixed solution of copper sulfate and sulfuric acid at about 70°C for 24 hours. After the test, the samples are cut open and checked under a microscope to see how deep the corrosion goes. The dezincification depth must be no more than 0.01 mm.
Finished product verification: We also test finished valve bodies. Samples are placed in corrosive water that copies real working conditions and are soaked on and off for up to 1000 hours. After this test, we check the pressure strength and sealing again. This makes sure the valve body still resists dezincification and works well even after machining and long-term use.
6. Is it possible to get PPAP documentation for my OEM Pressure Reducing Valves?
We can supply full PPAP files for your custom pressure-reducing valves. Our team is fully experienced in compiling these papers. We follow industry standards to put together complete PPAP documentation. These files suit overseas projects, large engineering works, auto factories, and industrial supporting businesses that have strict paperwork rules.
The full file pack covers part drawings, dimension test reports, and material certificates. It also includes process flow diagrams, production capacity analysis, initial process research, and measuring tool calibration records. All data matches products from formal mass production. Every detail is real and valid. We adjust each file one by one to fit the unique structure and production steps of your custom pressure-reducing valves.
We first send you digital copies of the finished documents for checking. We will provide printed versions once you give approval. We update the related PPAP files right away if we change production steps or raw materials later on. The updated files keep meeting your needs for reviews, factory inspections, and compliance records.
