China BS EN 593 Grooved Butterfly Valve D81X700 PN10/16 Manufacturer, Supplier, Factory

The internal anti-corrosion lining is fundamental to ductile iron pipe's performance and longevity in water systems. It provides essential protection against corrosion and erosion caused by the conveyed fluid, safeguards water quality, prevents leaks, and ultimately extends the pipe's service life decades beyond unlined alternatives.

Provide satisfactory solutions,products and services to customers.

The following points need to be considered when selecting a water meter: Measurement requirements: Select the appropriate water meter type according to the flow rate and accuracy requirements to be measured. Installation environment: Consider the environment in which the water meter is installed, such as whether special

The Flanged Resilient NRS Gate Valve with Bypass Outlet (Z45XL) is a gate valve combining resilient sealing (excellent seal, good impurity tolerance), flanged connection (reliable, easy maintenance), and a non-rising stem (space-saving). Its core value lies in the integrated bypass system, which is used to balance upstream and downstream pressure before opening the main valve. This significantly reduces operating torque and protects the main valve from damage caused by opening/closing under high differential pressure, ensuring safe, reliable, and long-term operation in critical applications. It is widely used in water systems, fire protection, and industrial settings requiring pressure equalization at pipeline control points. The model Z45XL explicitly identifies its flanged connection, geared operation (broadly), resilient seat, and bypass features.
