Piston valve 823

hydraulically-operatedpressure-controlpressure-reducing

Overview
Hydraulically operated control valve combining independent pressure sustaining and pressure reducing functions. It sustains a pre-set minimum upstream pressure regardless of downstream fluctuations, and prevents downstream pressure from exceeding a pre-set maximum irrespective of upstream surges.

Features & Benefits

• Robust piston-actuated structure – suitable for high-pressure service
• Line-pressure driven – independent control
• Elegant simplicity
  • Cost effective
  • Easy maintenance
  • Minimal external accessories
• In-line serviceable – easy maintenance
• Double-chamber design
  • Moderated valve reaction
  • Moderated closing curve
• Flexible design – easy addition of features
• Semi-straight flow – non-turbulent flow
• Stainless Steel raised seat – cavitation damage resistant
• Obstacle-free, full-bore – uncompromising reliability
• V-Port throttling plug (optional) – very stable at low flow

Typical Applications

• Municipal water systems – reducing pressure at potable water connections
• Water delivery networks – prioritizing upstream over downstream demand
• Distribution systems – maintaining upstream pressure during pressure drops
