Designed for Fire Systems That Remain Ready
Visible Stem Position
The OS&Y structure provides an externally visible stem position, allowing maintenance personnel to identify whether the valve is open or closed during inspection.
Full Flow Path
The gate design provides a straight-through flow passage when fully opened, reducing flow restriction within fire protection piping systems.
Standby Sealing Reliability
The resilient wedge sealing structure is suited for fire systems that remain pressurized and inactive for extended periods before emergency operation.
Corrosion Resistance
Fusion bonded epoxy coating on internal and external surfaces improves resistance against corrosion in water-based fire protection environments.
Internal Design Details
Ductile Iron Body
The ductile iron valve body provides the mechanical strength required for pressurized fire water applications and industrial pipeline installation.
EPDM Wedge
The encapsulated resilient wedge separates the sealing material from direct pipeline exposure, maintaining stable shut-off performance.
Stainless Steel Stem
The stainless steel stem provides corrosion resistance during long-term installation and periodic valve operation.
OS&Y Mechanism
The outside screw and yoke mechanism keeps stem movement visible, supporting inspection requirements commonly applied in fire protection systems.
