FAQs of Brass Pressure reducing Valve

1. How does a brass pressure-reducing valve work? 

From Fabio Malgorani

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. What is the pressure range of the brass pressure-reducing valve?

Plumberstar pressure reducing valve supports an inlet pressure of 0.2-1.6MPa. Their outlet pressure can be adjusted to 0.1-0.8MPa. You have special needs. We can design and customize high-pressure versions. High-pressure example: 2.5MPa. We can design and customize low-pressure versions. Low-pressure example: 0.05MPa. These versions adapt to different building pressures. They adapt to different equipment pressures.

3. What custom options are available for brass pressure-reducing valves?

Core Performance Parameter Customization

Pressure Regulation Range Customization
The conventional pressure regulation range is 0.02–1.6MPa. It can be adjusted to 0.01–2.5MPa (to match the valve body pressure rating).
Plumberstar manufactory also supports two-stage pressure regulation and segmented pressure regulation designs. They fit pipe network pressure fluctuations or multi-pressure range systems — like industrial workshops and building partition water supply.
Pressure Regulation Accuracy & Flow Customization
Standard pressure regulation accuracy is ≤±5%. It can be customized to ≤±3% (high-precision model). This model is suitable for use in laboratories, medical settings, and other similar environments.
The flow range can be optimized according to pipeline diameter and working conditions. We support small-flow precision control or large-flow rapid pressure regulation.
Temperature Resistance & Medium Adaptation
Conventional temperature resistance is -20℃ to 120℃. It can be customized to resist up to 150℃ (suitable for high-temperature fluids).
Seals have multiple options, including EPDM, PTFE, nitrile rubber, and others. They are compatible with various media, including gas, hot water, weak acids, weak bases, food-grade fluids, and more.

4. Can customers join design communication during pressure-reducing valve customization?

Yes! We confirm the design plan with customers in the initial stage of customization, including 3D/ CAD drawings. We will provide feedback on the progress of production and invite customers to confirm the key stage milestones (like sample production and batch testing).

5. Are 100% pressure tests performed before the brass pressure-reducing valve shipment?

All brass pressure-reducing valves pass three core factory tests: hydrostatic strength test (holds 1.5 times rated pressure), tightness test (holds rated pressure for 30 minutes, no leakage), and flow stability test. Test data can be compiled into a report provided with goods for customer filing.

6. What payment methods are available for the brass pressure-reducing valves?

We accept internationally recognized payment methods. They include T/T, 30% advanced payment, balance paid before shipment, sight L/C, DDU, DDP. You can negotiate special terms. Consider the order quantity. Consider our cooperation period. This ensures capital security for both parties.

7. What is the after-sales service if the pressure-reducing valve is damaged in transit after purchase?

We provide free replacement service. The product is damaged by logistics. Customers provide damage proof. Damage proof includes photos and logistics documents. We arrange prompt replacement. Customers do not bear extra costs.

8. What are the advantages of the pressure-reducing valves?

The four major advantages of Plumberstar brass pressure-reducing valves are as follows:

1. Customization ability is very strong, offering multi-dimensional customization that meets personalized needs.
2. The quality is reliable: 100% pressure-tested, 5-year guarantee, and a low defect rate.
3. The cost performance is high: supplies are directly from the factory, without intermediate links, giving a more favorable price for bulk purchasing.
4. Comprehensive services: free samples, free testing, and 72 hours of after-sales response.

9. How many years of experience in making brass pressure-reducing valves?

Plumberstar started producing valves and pipe fittings in 2006. We have over 15 years of industrial experience. We have 102 workers. These workers have more than ten years of working experience. We have 30 robotic machining centers. This ensures our stable monthly production capacity. Regular bulk orders are delivered within 30 days. Urgent orders can be delivered in 7-10 days. This ensures timely restocking for customers.

10. How does the reliable quality of the pressure-reducing valve protect the distributor’s reputation?

Plumberstar brass pressure reducing valves implement full-process quality control from raw materials to finished products.
Production stage
Precision casting plus CNC machining. Tolerance is controlled within ±0.02mm. 100% of products pass a 30-minute pressure holding test at 1.5 times the rated pressure. They also pass air-tightness and stable pressure accuracy tests.
Factory inspection stage
Every batch comes with test reports, certificates, and traceability codes. The qualified rate hits 99.9%.
This solid quality assurance means dealers barely have to deal with returns, maintenance, or claim disputes. It avoids valve problems like leakage, pressure regulation failure, and short service life. These issues would otherwise lead to end-customer complaints, bad reviews, or contract terminations — whether the customers are engineering companies, home improvement firms, or homeowners. It even prevents damage to your local market reputation.
