Brass Pressure Relief Valve Manufacturer in China

Trusted China-Based Manufacturer of Brass Pressure Relief Valve

As a trusted domestic Chinese manufacturer, TREX specializes in the R&D and production of brass pressure relief valves (safety valves), providing overpressure protection for booster pump sets, hot water and heating systems, solar and heat pump installations, pressure tanks, and water purification equipment. The valve body is constructed from hot-forged brass (with options for DZR dezincification-resistant or low-lead materials) and features precision CNC machining, a spring-loaded mechanism, and a soft-seal design. This combination ensures precise opening pressure, high operational repeatability, and tight, leak-free reseating. Standard port sizes include 1/2″, 3/4″, and 1″ (available in BSP or NPT threads), with a standard set pressure range of 1–16 bar (calibratable upon request).

The operating temperature range for the medium is -10°C to 120°C (high-temperature versions are available). Various structural configurations are offered, including straight-through or 90° outlet designs, models with drain ports or hose connections, and top caps that can be lead-sealed to prevent accidental tampering. Sealing components are available in materials such as EPDM, NBR, or PTFE to suit applications involving hot and cold water, air, and non-corrosive fluids.

Advantages of Brass Pressure Relief Valve

High strength and durability, with brass construction providing excellent resistance to pressure and mechanical wear.
Reliable pressure regulation, automatically releasing excess pressure to protect pipelines and equipment.
Corrosion-resistant material suitable for long-term use in water and irrigation systems.
Stable performance under varying temperatures and pressures, ensuring safe and consistent operation.

Different Types of Brass Pressure Relief Valve

TR0060

This brass pressure relief valve features a hot-forged brass body and a spring-loaded mechanism. A top-mounted adjustment screw allows for the precise setting of the opening pressure; upon overpressure, the valve opens rapidly to discharge laterally, then reseats tightly without leakage. Suitable for non-corrosive media such as water and air, it is widely utilized for overpressure protection in pump assemblies, pressure tanks, and boiler or solar energy systems. It features standard internal threaded connections (with BSP and NPT options available) and comes in common sizes ranging from 1/2″ to 1″; its compact, corrosion-resistant design ensures easy installation and maintenance.

TR0061

The TR0061 Brass Pressure Relief Valve (Nickel-Plated Surface) features a spring-loaded design with a top-mounted pressure adjustment mechanism. It offers an adjustable opening pressure, provides rapid lateral discharge in the event of overpressure, and ensures tight, leak-free reseating. It utilizes internal threaded connections (BSP/NPT options available) and is commonly available in sizes ranging from 1″ FF to 2″ FF. Suitable for non-corrosive media such as water and air, it is widely employed for overpressure protection in booster pumps, pressure tanks, heating systems, solar energy systems, and similar applications. We support OEM customization for parameters such as pressure settings, connection types, and branding/logos.
