Grooved Butterfly Valve
1. What is a grooved butterfly valve? What are its core strengths? The grooved butterfly valve is a butterfly valve that uses a clamp connection method. Its core advantage is that it is extremely convenient to install and disassemble, without the need for complicated welding or threading operatio...Read more -
Butterfly valve soft seal and hard seal
1. What is the fundamental difference between soft seal butterfly valve and hard seal butterfly valve? The sealing ring material is different. The sealing pair of a soft-sealing butterfly valve is “metal seat + non-metal sealing ring”, and commonly used materials include rubber (EPDM/...Read more -
Butterfly Valve Used in Municipal Water Supply Project
Municipal water systems need durable valves for high flow, changing pressure, and varied conditions. Butterfly valves are popular in medium-to-large pipelines for their compact design, fast action, and cost-effectiveness. But choosing one isn’t just about size—material, disc, seat, connecti...Read more -
Rubber Joint
1. What is a rubber joint? What is its function in piping systems? Rubber joints, also known as rubber soft joints and flexible rubber joints, are flexible connecting elements installed between valves and pipes. Its core functions include four points: vibration reduction and noise reduction ̵...Read more -
ISO Butterfly Valve Standard Overview
I. Why butterfly valve standards are important? The standard specifies the design of butterfly valves and the tests that each valve must pass. Without these standards, the security of the system cannot be guaranteed. Valves cannot be aligned, components cannot match, and the entire piping system ...Read more -
Stainless Steel vs. Duplex Stainless Steel
1. What is stainless steel? What is duplex stainless steel? Stainless steel is a general term for a type of corrosion-resistant steel, and its types are mainly classified based on the microstructure. Common ones include austenitic stainless steel (such as 304, 316) and ferritic stainless steel. D...Read more -
Common faults and troubleshooting methods of butterfly valves
As the core control component of the pipeline system, butterfly valves are widely used in water supply and drainage, HVAC, chemical industry and other fields. They are popular because of their compact structure and fast opening and closing. However, leakage, jamming, opening and closing failure a...Read more -
Epoxy spraying and Halar coating
I. What is epoxy spray coating? Epoxy spray coating is a two-component coating with epoxy resin as the main film-forming substance. It is applied to the metal surface by spraying or brushing to form a protective layer. It is characterized by strong adhesion and excellent resistance to cathodic pe...Read more -
Ductile Iron Valves vs. Cast Iron Valves
1. What is Ductile Iron? Ductile iron is a type of iron that has enhanced strength and flexibility compared to traditional cast iron. This is achieved by adding small amounts of elements like magnesium to the iron during the smelting process. The result is a material that can withstand higher str...Read more -
Valve seals: How to distinguish and select PTFE, EPDM, and PFA valve seats?
1: What is the most essential difference between PTFE, EPDM and PFA materials? PTFE (Polytetrafluoroethylene): Commonly known as the king of plastics, it is a white solid with excellent chemical inertness and temperature resistance (-196℃~+200℃). It has an extremely low friction coefficient, but ...Read more -
Frequently asked questions about pipeline air release valve
1. Why do pipelines need to be equipped with air release valve? When pipes are filled with water, run, or drained, air can accumulate inside them. If it is not discharged, “air blockage” will be formed, which will reduce the water cross-section and increase energy consumption. In seve...Read more -
How to Choose the Right Butterfly Valve for Water Treatment
Water treatment facilities are instrumental in providing clean and safe water for many different application. Butterfly valves are one of the most important components in a water treatment facility as they are utilized to control water flow and the amount of chemicals distributed. The selection o...Read more
