EAC Marked Telescopic Direct-Buried Gate Valve for Russian Infrastructure Projects

For municipal water supply, fire protection, and industrial systems, resilient seated gate valves or metal seated gate valves are recommended. These valves provide full bore flow with extremely low pressure drop. It is important to select the appropriate pressure rating (PN10/PN16) and material (ductile iron or cast steel) based on the working conditions to ensure long-term reliability and tight shutoff.

Gate valves are ideal for fire protection systems and pump stations because they offer minimal flow resistance when fully open and excellent sealing performance when closed. Their robust construction can withstand high pressure surges, making them a preferred choice for main pipelines where reliable on/off control is critical for safety and system performance.

Traditional gate valves are designed primarily for infrequent on/off operation rather than frequent cycling. For applications requiring frequent operation, it is recommended to choose high-quality resilient seated gate valves with gear operators or pair them with electric actuators. Proper maintenance of the stem and sealing surfaces can significantly extend service life even in demanding conditions.

Gate valves are widely used in HVAC and chilled water systems due to their excellent sealing capability and very low pressure loss when fully open. They provide reliable isolation for maintenance and repair work. Their durable design and bubble-tight shutoff help maintain system efficiency while effectively preventing internal leakage in heating and cooling circuits.
