Rising stem cast iron gate valve and concealed stem cast iron gate valve are two main structural types of gate valves. The core difference lies in the design and movement of the valve stem, which leads to different operating characteristics, applicable scenarios and maintenance requirements.

BS 5153 Check Valve Product Introduction The following will introduce BS 5153 check valves in terms of manufacturing experience, technical characteristics, quality assurance and after-sales service .

Four-inch flange cast iron gate valves are widely used in industrial piping systems due to their pressure resistance, corrosion resistance and long life, such as water treatment, petrochemical, HVAC and other fields. However, there are many types of products on the market with varying quality. How to correctly select a valve requires a combination

A check valve is a valve whose opening and closing parts are circular discs and which rely on their own weight and medium pressure to produce movement to block the backflow of the medium.

​The wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. The gate is called an elastic gate.

According to the design requirements, the valve body of the gate valve and various casting parts with complex shapes suitable for gate valve production need to be produced by casting.
