What‘s the advantage of Nickel-Aluminium Bronze Valves?

Aluminum bronze valves are highly suitable for corrosive, saline environments. The common specification is ASTM B148 C95800 although the AB2 specification is also used. These are similar to C95500 and C95400 specifications and offer good castability, reasonable bearing material, easy machining and high tensile strength. Aluminum-bronze valves are a suitable and far cheaper substitute to duplex, super duplex, and monel for many seawater applications, especially in low-pressure applications....

What Is the Cracking Pressure of Check Valves?

Check valves are used in a wide range of industrial processes. While selecting the correct check valve design and materials for your application is important, it can be equally important to pay attention to what differential pressure is required to open the check valve. Spring-loaded check valves have a spring that is activated by the pressures in the media, which open and close the valve. In spring-loaded check valves, the cracking pressure is determined by the spring setting and...

DN2000 Expansion Joint Start Working for Ho Chi Minh Main Water Supply Line

On Apr.25th, 2023, workers are busy working to assemble the DN2000 bellow type expansion joint to the main water supply line in Ho Chi Minh City, Vietnam.

How to Select between Gate Valves and Butterfly Valves

Gate valves and butterfly valves play the role of shutoff and regulating flow rate in pipeline use. Of course, there are methods in the selection process of a butterfly valve and gate valve, how to choose: gate valve and butterfly valve in the water supply network in order to reduce the depth of soil, generally large diameter pipe with butterfly valve, the impact on the depth of soil is not big, strive to choose the gate valve, but the price of the same specification of a gate valve is higher than...

High Performance Butterfly Valve

A High-Performance Butterfly Valve(HPBV) can handle more critical services other than general water and air at a wider temperature and pressure range. Normally the Double Offset and Triple Offset butterfly valves can be used as High Performance, as they are more suitable for higher pressure, temperature and various fluid. Double Offset Butterfly Valve (Soft Seat) Triple Offset Butterfly Valve (Metal Seat) Compared with Concentric Butterfly Valves, they have unique design of offsets between shaft/disc/seat...
