Leakage, corrosion, abnormal pressure, difficult operation and water hammer may appear as separate problems, but they are often closely related. For example, worn valve seats can […] - [Valve Components Guide: Understanding the Valve Body, Bonnet, Seat, and Stem](https://plumberstar.com/valve-components/): A valve is a precision mechanical assembly made up of multiple components that perform different functions while working together. The long-term reliability of an industrial valve depends on the design, material selection, and manufacturing quality of each component. This article systematically explains the most important valve components, including the Valve […] - [Valve Specification Guide: Pressure Ratings, Connection Types & Valve Dimensions](https://plumberstar.com/valve-specification/): Selecting valves for an industrial project involves much more than choosing the valve type and size. Two DN100 ball valves may have the same nominal size, but differences in pressure rating, connection type, material specification, or installation dimensions can prevent them from meeting the design requirements or fitting the existing […] - [Valve Manufacturing Process Guide: Forging, Casting, Extrusion, Injection Molding and Machining Processes](https://plumberstar.com/valve-manufacturing-process/): In industrial projects, valve quality is closely related to the manufacturing process. Even when valves use the same material standards, different manufacturing methods, such as forging, casting, extrusion and injection molding, will affect mechanical performance, dimensional accuracy, service life and applicable operating conditions. Understanding these processes helps engineers evaluate product […] - [Valve Standards Guide: Certifications, Testing Requirements & Compliance](https://plumberstar.com/valve-standards-guide/): In valve projects, certification documents do not always match the products being purchased. A certificate may cover only part of a product range but be presented for the entire series. A test report may simply state “Pass” without recording the test pressure, holding time, or test medium. Sometimes the valve […] ## Products - [90 Degree Radiator Replacement Angle Adaptor](https://plumberstar.com/product/angle-adaptor-90-degree-for-replacement-radiator/): This is our 90 Degree Radiator Replacement Angle Adaptor, built to replace worn-out radiator fittings. It has a tough plastic shell paired with a solid brass threaded tip. This right-angle fitting connects radiators to heating pipes with a precise fit. It mainly guides smooth hot water flow at 90 degrees and fixes leaky connections on aged radiator units. Its standard female brass threads fit most regular radiator ports. Homeowners finish DIY installs easily, no extra fittings or special tools required. It withstands daily heating temperatures and working pressure. Install once, and it keeps radiator pipes tightly fixed for reliable long-term heating. Model No.: JX-10120 Media: Water Material:‎Plastic Connector fitting material: Steel Included Components: Angle adapter 90 degrees Size:‎M30 x 1,5 mm For radiators with separate valves Allows installation of thermostatic heads at a right angle to the wall Suitable for mounting on both left and right sides Screw connection - [1Inch Bronze Gate Valve](https://plumberstar.com/product/1inch-bronze-gate-valve/): This is a 1-inch bronze gate valve. It blocks flow in straight pipelines. It has a green handwheel on top. Turn it many times, and the screw stem lifts the wedge gate inside to open or close the valve. The wedge disc presses firmly against the valve seat. It seals well and stops water completely when shut. This valve works for water supply, drainage, heating, and cooling systems, and small industrial water pipes. It is widely used in these places. Model No.: JX-10123 Size: 1/2"-4" Material: Bronze, C86400 Connection type: BSP Steering Wheel Material: Aluminum Working pressure: 200WOG Temperature rated to 180° F Solid wedge disc Surface: Origin Non-rising stem Nut material: Steel Gasket: PTFE Standard: ANSI OEM and Custom are available Free samples Free inspection report - [Angular Globe Fire Angle Valve](https://plumberstar.com/product/angular-globe-fire-angle-valve/): This is our angular globe fire angle valve for fire service pipeline flow control. Made of epoxy-coated cast iron with a stainless steel stem and a cast iron handwheel, it connects fire pipes via standard grooved ends. It cuts off or regulates fire water flow at an angle and stops pipeline leaks. Quick installation fits common fire piping without extra parts. It handles regular working pressure and temperature. It keeps tight, long-lasting sealing for fire protection systems. Model No.: JX-10122 Size:2-1/2" Body Material: Ductile Cast Iron Steering Wheel Material: Aluminum Body Material: Ductile Cast Iron Working Pressure:1.6Mpa Breaking Pressure:6.4Mpa Height:185mm (Open)/160mm (Closed) Length:137mm Weight: About 1.3KG OEM and Custom are available Free samples Free inspection report - [45°Fire Angle Globe Valve](https://plumberstar.com/product/45fire-angle-globe-valve/): This grooved fire angle valve is made of ductile iron and has a rust-resistant red baked-on paint finish. capable of enduring long-term high-pressure fire water service. Its 45°-angled inner bore reduces flow resistance compared with straight-type valves, reducing pressure drop during water delivery and boosting discharge efficiency. The bottom uses a grooved clamp connection for fire steel pipes, and the side male thread links to fire hydrant or hose connectors. Both connection styles conform to prevailing fire pipeline installation standards.
