| Pump Group Underfloor Heating Circuit Mixing Distributor This pump group mixing distributor is the main control unit for underfloor heating systems. It combines a mixing valve, circulation pump, and pressure gauge in one compact unit. The system mixes hot water, drives water circulation, and controls pressure at the same time. It is built to meet the flow and temperature needs of underfloor heating. Putting all key parts together makes installation easier and daily maintenance simpler. It is a practical core component for residential underfloor heating setups.

| Threaded Angle Radiator Valve Thermostatic type This thermostatic threaded angle radiator valve is a specialized 90° angle temperature control fitting engineered for radiator-based heating systems. Enabling direct connection to radiators and heating pipelines. Equipped with a temperature-control head marked with clear temperature scales, it allows manual presetting of the target temperature via rotating the scale dial. This adjusts the hot water flow to the radiator.

Brass Pressure reducing Valve
Brass Pressure reducing Valve
Brass Pressure-Reducing Valve
This brass pressure-reducing valve is a special pressure control device. It’s made for fluid systems. It has a multi-port valve body. Equipped with integrated pressure-regulating components, it automatically reduces incoming high-pressure fluids to a preset low-pressure level. Then it keeps the pressure stable. With automatic pressure regulation built in, the valve reduces the need for manual adjustment and is widely used in many fluid pipeline systems.

1. How does a brass pressure-reducing valve work?
The working principle of the brass pressure relief valve core is simple. It uses medium-pressure feedback to automatically adjust the valve core opening. It stabilizes the incoming high pressure into the set low-pressure output.

2. Can you provide the flow rate charts (Cv values) for your different PRV sizes?
We supply full flow curve charts and matching Cv flow coefficient data for every size of our brass pressure reducing valves. Every bore size model runs real performance testing on professional fluid test benches before shipment. Documents cover all standard sizes, including 1/2″, 3/4″, and 1”. Each valve model has its own independent flow curve graph, with tested Cv values under actual working conditions clearly labeled to show real flow capacity directly. You can ask your sales contact for PDF charts and flow data sheets to check before confirming orders. For large OEM project batches, we pack printed flow performance reports together with finished goods.
3. What is the lead time of the brass pressure-reducing valve?
Our brass pressure-reducing valves split into two delivery cycles: stock items and custom orders. Common standard sizes are kept in finished warehouse stock. Once payment clears, packing and shipping will be finished in 1–3 working days. If our regular ready-made valves sell out, standard production takes 15 to 20 working days. This time includes cutting brass valve bodies, fitting inner parts, hydraulic pressure tests, surface plating, and final packaging. When orders pile up in busy seasons, waiting time stretches to 20–25 working days. Our sales staff will tell you the new timeline early. Any custom changes add 5 to 10 extra working days. These custom requests cover your own brand marks, unique pressure settings, special thread sizes, and matching custom pressure gauges. If you hold long-term bulk supply contracts, send over your sales estimates in advance. We set aside fixed production space just for you to shorten your wait time.
4. Can the finishing of the brass pressure-reducing valve be customized?
We run our independent polishing and electroplating workshops, and supply custom surface finishes for all brass pressure-reducing valves. Bright chrome plating is our standard option; clients can also pick matte nickel or polished bare brass as alternative finishes. For one single bulk order, we can split production to make valve bodies with two separate surface treatments at the same time.
We set fixed operation steps and sampling rules for every custom finish to keep surface texture consistent. Custom bright chrome needs one extra heavy polishing pass. Matte nickel skips the chrome top layer and uses a thicker nickel coating instead. Polished natural brass only gets fine buffing with no electroplated protective layer added.
We pick random pieces out of every production batch. These samples go through a 48-hour neutral salt spray test. If any sample has peeling coating, rust spots, or uneven surface color, the whole batch goes through rework. All plating raw materials we use meet environmental requirements and satisfy global standards, including EU RoHS and US NSF.
5. Are pressure tests performed before the brass pressure-reducing valve shipment?
We test every brass pressure-reducing valve one by one before delivery, no exceptions. We use dedicated hydraulic test machines with accurate digital pressure sensors.
We test valve strength at 1.5 times the standard working pressure and hold this load for a full minute. Any valve with cracks, permanent shape changes, or liquid leaks gets discarded right away. The sealing test monitors every joint and internal seal non-stop. Valves only move to the next stage if no leaks show up at all. When testing pressure adjustment, outlet pressure can only shift ±5% from the set value you request.
We store all test records matched to each production batch. Faulty valves get pulled out immediately for repair. They cannot be packed or shipped until they pass all tests again.
6. Can you customize the brass pressure-reducing valve according to my market?
Plumberstar can fully customize brass pressure-reducing valves for your target market. This is one of our core strengths. We have long experience serving customers all over the world. We consider your local market fully. This includes usage habits, installation standards, water quality, pressure environment, certification requirements, and local preferences. We can adapt many things. These include product structure, specifications, materials, surface treatment, packaging, LOGO, and all documents. The product will be more competitive and fit your market better.
We make precise adjustments for different regions.
- For Europe: We use BSP threads. We meet EU drinking water and low-lead standards. We match local water pressure. We support CE, ACS, and other certifications. Appearance and interface fit local boilers, heating, and water supply systems.
- For North America, we use NPT threads. We meet NSF 372/61 low-lead standards. We use psi as the pressure unit. It fits local residential and commercial projects. It passes the project acceptance smoothly.
- For the Middle East, Southeast Asia, and other harsh environments, we improve valve anti-corrosion and seal anti-aging. We use more durable materials. We make the product more stable and long-lasting in tough conditions.
We also offer deep customization. You can choose appearance, LOGO, pressure preset, and packaging. You can pick surface treatment: polishing, nickel plating, matte. We can print your brand on the valve, gauge, and box. We can preset the pressure to your local common value. You can use it directly after installation.
