Aside from quality and price, the biggest advantage of choosing Plumberstar is our product versatility, flexible customization, and reliable mass production that greatly lowers your operating costs. Our three-way temperature control valve features universal 3/4 inch dual male and female thread connections, fitting most household and commercial pipelines like underfloor heating systems and water heaters. Unlike ordinary single-specification valves that force you to stock multiple models, this single valve adapts to almost all daily hot water scenarios, simplifying your inventory management.

Our valve packs all handy functions into a single unit. We can tweak its small parts for you and still follow safety rules from every country, something most other factories struggle to pull off well. This valve works great for Europe, the US, Australia, and lots of other common markets: we swap its temperature control parts, use safe lead-free brass to match local water laws, and hand over all official certification papers you need. If you want to change how the water pipes connect, stamp your brand name onto the valve, or swap the blue top cap, you won’t need to pay extra money for costly new metal molds. Small-batch custom orders are fully supported without extra high fees.

 

Our standardized production lines guarantee steady product quality and predictable lead times. This valve reduces incoming 8 bar water pressure down to a safe constant 3 bar output, and it can handle up to 10 bar peak supply pressure without pressure or temperature fluctuations. Every unit goes through complete testing on our exclusive production lines. Custom bulk orders stick to a consistent 30-day production schedule, so you won’t face shipping delays or buyer complaints. This single all-purpose valve works for all heating and hot water systems, letting you cut down inventory stock and lower ongoing business costs.

Our thermostatic reducing valve delivery time depends on whether you need custom adjustments. We always stock key brass parts for standard non-custom valves. Every unit passes pressure and temperature tests to meet 8 bar inlet / 3 bar outlet standards, then ships out in 14 to 15 working days.

Any custom orders, whether you need adjusted pressure or temperature values, brand engraving, special surface treatment, or custom packaging, take 30 to 35 working days in total. This timeline includes tweaking molds, confirming pre-production samples, mass manufacturing, and complete quality testing on all finished valves. If you have an urgent delivery deadline, we can arrange priority production to speed up shipment while keeping full quality standards intact.

For our long-term regular customers, we pre-stock mainstream valve bodies and key internal parts in advance. This stock preparation greatly shortens the delivery cycle, helping you get stable supplies faster and better support your ongoing engineering projects and product sales.

 

Plumberstar sets different delivery schedules for thermostatic reducing valves based on whether you place a standard order or a customized OEM order. When raw materials are fully stocked, our unmodified standard valves take roughly 14 to 15 working days to ship out. This timeline covers the whole workflow: manufacturing each valve, carrying out mandatory pressure and temperature performance tests, product packaging, and preparation for shipment.

Delivery periods will be extended if you need fully bespoke OEM versions of this valve. We can make lots of changes to your valve. We can build brand-new molds using your drawings, change parts inside the valve, set fixed water pressure and temperature you like, add extra holes to test water, put in parts to stop water from flowing backward, change how the valve’s outside looks, and make special boxes to pack the valves. If you want all these custom changes, we need about 30 to 35 work days. This time includes fixing molds, making sample valves for you to check, making all your valves in large amounts, and carefully testing every finished valve.

We offer flexible production arrangements to fit tight project timelines. If you need your valves fast, we will make them first to save your waiting time, and we never cut corners on quality to hit your project due date. For our regular long-term buyers, we keep plenty of standard valve shells and key inside parts ready in our warehouse. This shortens your wait a lot, so you can always get enough goods to sell or finish construction jobs smoothly.

Sure, we can. Plumberstar makes custom valves just for you. We can sell you thermostatic mixing valves with small built-in holes. You can use these holes to easily check the water’s temperature and pressure. We machine standard thread ports directly on the brass valve body, covering common sizes G1/8”, G1/4”, 1/8” NPT, as well as 1/4” NPT. You can hook up pressure meters and temperature readers straight to these holes when you set up the valve. No extra small connecting parts are needed. It lets you easily see the water pressure and heat level inside the pipes right away.

We make these test holes match the valve’s shape perfectly. They won’t mess up any of the valve’s main jobs: keeping water temperature steady, lowering water pressure, and stopping water from flowing backward. These additional openings will not weaken the overall structure of the valve body in any way. We put small dust caps on every test hole before sending out the valves. These caps stop dirt and tiny bits from getting inside while the valves are shipped and when you install them. We can also make special changes for you. We can add test holes on both the water-in and water-out sides to check water data separately. We can change the screw size, hole depth, and where the holes sit so they fit your testing tools perfectly.

Every TMV with test holes gets its own full leak and pressure test after being put together. This makes sure no water will leak out of the test holes, and the valve can work well for a very long time. We can add these temperature and pressure test holes easily. It does not matter if you just change our regular valve or ask us to make a totally new valve from your drawings. These holes help you test the water pipes when you set them up, check them for project approval, and fix them regularly later.

We take IP protection for your OEM thermostatic reducing valve designs extremely seriously. Before starting any custom development, we sign a formal legal NDA to fully secure your drawings, 3D files, and exclusive specs like the 3/4 inch thread size and 3–10 bar pressure range. All your proprietary design data is strictly private, only used to produce your own products and never shared or resold to any other clients.

We have tight rules for managing design files and production work. Your confidential design documents are stored under encryption, and only three specific team members from design, production, and QC can open them. All custom molds and tools built specifically for your valves receive unique labels and are stored in separate areas. We log every time these tools are used or repaired, so they will never be used for other customers’ orders. Your OEM goods are manufactured and packed in separate work zones to prevent mix-ups and design leaks.

We also follow strict permanent confidentiality rules across our whole factory. Any staff working on your OEM project has to sign an internal secrecy agreement, and they are not allowed to take photos or pass your design information to outsiders. All production records and test papers for your custom valves are filed separately and stored under encryption at all times. If third-party inspectors come to the workshop, we will hide all your exclusive design materials right away and only show standard public product info, so your unique valve designs stay safe, and your market edge stays protected.
