Stainless Steel Non-Rising Stem Resilient Seat Gate Valve
Product Introduction
The stainless steel non-rising stem resilient seat gate valve features a 304/316 stainless steel body with fully enclosed stem design, optimized for space-constrained piping systems. Ideal for underground pipelines, marine applications, and industrial equipment, its EPDM/NBR seat achieves bidirectional bubble-tight sealing at PN16 pressure, suitable for water, oils, and mildly corrosive media up to 80℃.
Product Features
- Full Stainless Construction: Corrosion-resistant body, disc, and stem.
- Compact Non-rising Stem: 30% height reduction for confined spaces.
- Resilient Sealing: EPDM/NBR seat accommodates pipeline deformation (50,000+ cycles).
- Low-torque Operation: Self-lubricating stem bearings reduce handwheel torque by 35%.
- Global Compliance: ISO 5211 flanges ensure worldwide pipeline compatibility.
