bs5163 задвижка с упругим седлом

BS5163 is a British Standard specification for resilient-seated gate valves used for waterworks purposes. Resilient-seated gate valves have a rubber or elastomer seat that provides a tight seal against the gate when the valve is closed, preventing any leakage through the valve.

The gate valve is a type of valve that controls the flow of fluid through a pipeline by using a gate or wedge mechanism to either block or allow the flow. In the context of BS5163, the resilient-seated gate valve would typically have a flanged end connection and be suitable for use in water supply and distribution systems, очистные сооружения, and other industrial applications where a reliable and maintenance-free valve is required.

The BS5163 standard ensures that metal seated gate valve manufacturers to this specification meet certain quality and performance requirements, such as the ability to withstand a certain level of pressure and temperature, and to maintain a tight seal over a specified period of time. The standard also specifies the materials that can be used in the construction of the valve, such as cast iron or ductile iron for the valve body and gate, and EPDM rubber or a similar material for the seat.

Wholesale bs5163 задвижка с упругим седлом are a popular choice for waterworks applications due to their ability to provide a tight seal, даже в условиях низкого давления, and their low maintenance requirements. The rubber or elastomer seat helps to prevent corrosion and scaling, which can affect other types of valves.
