Product Q&A

Q:How to choose the right gate valve for water & industrial pipelines?

For water supply, fire protection, & industrial systems, resilient or metal seated gate valves are ideal. They offer full bore flow with low pressure drop. Choose the right pressure rating (PN10/PN16) & material (ductile iron/cast steel) for reliability & tight shutoff.

Q:What makes gate valves suitable for fire protection & pump stations?

Gate valves are ideal for fire systems & pump stations due to minimal flow resistance when open & excellent sealing when closed. Their robust build withstands high pressure surges, making them ideal for main pipelines needing reliable on/off control.

Q:How do gate valves perform in high-frequency operation & automation systems?

Traditional gate valves are for infrequent on/off use, not frequent cycling. For frequent operation, choose resilient seated gate valves with gear operators or electric actuators. Proper stem and seal maintenance extend lifespan even in tough conditions.

Q:What are the advantages of using gate valves in HVAC and chilled water systems?

Gate valves are perfect for HVAC and chilled water systems due to excellent sealing and minimal pressure loss when fully open. They ensure reliable isolation for maintenance and repairs. Their durable design and bubble-tight shutoff boost system efficiency, preventing internal leakage in heating and cooling circuits.
