| Pressure Reducing Valve This pressure-reducing valve has a sliding sensor piece inside; it automatically opens or closes based on the water pressure coming out. There’s a twist knob on the top so you can easily set your ideal output pressure to match different pipe systems. People often install it on home water pipes, boiler lines, and factory fluid pipelines.

| Brass Automatic Boiler Fill Valve This brass automatic boiler fill valve is a pressure-activated water refill device. It’s made for hot water and hydronic heating boiler systems. When the system pressure drops below the set level, the valve opens on its own. It refills water into the boiler automatically. When pressure goes back to normal, the valve shuts off right away. No manual operation is needed at all. There’s an adjustment knob on it. You can set the refill pressure easily with it. It fits different boiler types and system setups perfectly.

| Nickel-Plated Radiator Valve This nickel-plated radiator valve is a three-way flow control fitting used in heating systems. It has three ports and is designed for water distribution and collection in radiator branch circuits. The three-port layout lets it connect the main heating pipe and individual radiators at the same time. This simplifies the pipe setup and avoids the need for extra adapters. The valve allows manual flow adjustment to control how much heat each radiator gives off. It also helps balance the system, reducing uneven heating and keeping room temperatures more stable across the whole system.

| 4-Way Fan COil Valve This 4-way fan coil valve is used for water flow control in fan coil unit (FCU) systems. It has four ports that match the water connections between the fan coil and the main pipeline. The four-port design allows it to connect the fan coil inlet, outlet, and the system pipes at the same time. It can open or shut off the water flow, and it also supports flow direction change when needed. A white knob on the top is used for manual control. By turning the knob, the valve opening can be adjusted to control the flow rate and meet the cooling or heating needs of the fan coil. It is a key control component for water circuits in central air conditioning fan coil systems.

| Thermostatic Mixing Valve This thermostatic mixing valve keeps your water temperature consistent, it automatically mixes hot and cold water in the right amounts so the water coming out never gets too hot or freezing all of a sudden, a twist knob on top lets you pick your preferred warm temperature easily, you’ll find this valve on shower sets and underfloor heating manifolds, steady warm water feels much nicer to use and stops you from getting burned by overly hot water.

|
| 3 Way Thermostatic Mixing Valve This 3-way thermostatic mixing valve is used to control water temperature in multi-branch plumbing and underfloor heating systems. It outputs mixed water with a stable temperature. Perfect for underfloor heating zones and bathroom systems with multiple water outlets. There’s an orange knob on top. You can turn it by hand to set the needed temperature. It’s a key temperature control part. Great for systems that need a stable and reliable mixed water supply.

1. What’s the difference between a pressure-reducing valve and a pressure relief valve?
The pressure-reducing valve is an active device that regulates pressure. It uses the cooperation of the diaphragm, spring, and feedback mechanism. When upstream and downstream pressures fluctuate, the valve core automatically adjusts its opening. It keeps the downstream pressure constant. It’s suitable for continuous operation conditions that need stable low pressure. Like commercial buildings, water supply and pressure reduction are at the front end of industrial equipment.
The pressure relief valve is a passive safety protection device. It stays normally closed. It will only open automatically to release pressure when the system pressure exceeds the preset starting pressure. It closes again when the pressure drops to the safe return pressure. It has no pressure regulation or stabilization function.

2. Is a built-in pressure gauge available for the adjustable pressure-reducing valve?
Plumberstar’s adjustable pressure-reducing valves can have a built-in pressure gauge. We can add it based on your system needs, installation habits, and target market. It makes on-site pressure checking and adjustment much easier.
Our built-in pressure gauge is directly part of the valve body. You don’t need an extra port for an external gauge. The whole structure is smaller and saves space during installation. It’s great for tight spaces, like wall-hung boilers, solar systems, heating lines, and home water pipes.
The pressure gauge matches the valve’s pressure range. Common ranges are 0–10 bar and 0–16 bar. The scale is clear and easy to read. You can see pressure changes in real time when adjusting the outlet pressure. You can set the exact pressure you need. No need to buy or install extra external tools.
3. Can pressure be locked after adjusting the adjustable pressure-reducing valve?
Our adjustable pressure-reducing valves use brass lock nuts. After you finish setting the water pressure, tighten this nut to lock the adjustment position. Workers use fixed-torque tools during assembly to lock every nut with an identical clamping force. This stops the adjustment screw from spinning loose over time.
The inner wall of each lock nut is cut with anti-slip serrations. These teeth hold tight against vibration from constant pipeline water flow, so the preset outlet pressure does not drift during long-term use.
Before shipment, we pre-adjust each valve to the target pressure you request, then run a hold test to check locking reliability. We feed steady 0.7MPa inlet water for 30 minutes straight and record the outlet pressure every 5 minutes. We retain batch production and quality control records for all finished items, so every production step can be fully traced.
4. Is pressure testing performed before pressure-reducing valve shipment?
Yes, every adjustable pressure-reducing valve from Plumberstar goes through a full pressure test before leaving the factory. We use professional water pressure testing equipment. We test each valve one by one for shell strength, sealing, and pressure adjustment.
- First, we test the valve body at 1.5 times its rated pressure. We make sure it does not leak, deform, or crack under high pressure.
- Next, we run a low-pressure sealing test. We check key parts like the valve disc and sealing ring. They must seal tightly with no internal or external leaks.
- We also adjust and test the pressure function on every valve. We check if the adjustment runs smoothly, if the pressure stays stable, and if the delay is within standard.
All tests are done on a standard production line. Special staff record all test data. Only qualified products go to packaging. Failed ones are stopped and reworked. They never move to the next step.
5. What is the MOQ for the adjustable pressure reducing valve?
Plumberstar has different MOQ levels for adjustable pressure-reducing valves. It depends on whether you choose standard models or need OEM customization. Our policy is flexible and meets the real needs of foreign trade customers. We don’t set high barriers for trial orders, market tests, or projects.
