FAQ

Q1: Why choose rising stem over other valves?

Three key advantages for water systems:
① Visual status check – See open/closed position instantly
② Easy troubleshooting – Sticking stems reveal debris early
③ Simpler repairs – Replace gland packing without pipe disassembly
Unlike non-rising valves, it avoids hidden failures in critical water shutoffs.

Q2:Are DN100 PN16 gate valve cost-effective for large water projects?

Absolutely – their simple mechanical design reduces upfront costs versus automated valves, while the visible stem minimizes maintenance expenses. Ideal for:
·Municipal water distribution networks
·Apartment complex plumbing
·Farm irrigation systems
Installation requires no special tools: align flanges, insert EPDM gaskets, and tighten bolts evenly. For DN200+ pipelines, add pipe supports near valves. Avoid exposing to direct sunlight for years to prevent UV degradation.

Q3:Which valve is easiest to maintain?

Rising Stem: Simplest – lubricate exposed threads; replace packing without disassembly.
Non-Rising Stem: Harder – debris can jam hidden stems; may require removal.
Underground: Toughest – if buried deep, excavation needed for repairs.

Q4:When would I choose a gate valve over a check valve?

Pick a gate valve when you need:
Manual flow control (start/stop water intentionally)
Visual confirmation of open/closed status (rising stem shows position)
Full flow with minimal pressure drop
Choose a check valve only for automatic backflow prevention (e.g., pump outlets). Gate valves suit manual shutoff in building water lines, fire systems, or irrigation where human control is essential.
