The Bray S85 Series is a two-piece, full-port threaded ball valve with NPT threaded connections, suitable for NPS ½ to 3 (DN 15 to DN 80) piping. The body and ball are made of CF8M stainless steel, and RPTFE seats provide zero leakage. It is suitable for service at 1000 psi WOG and temperatures from -46°C to 232°C. Applications include potable water treatment, small-bore sour oil and gas pipelines, and automated isolation in hazardous areas.

Application scenarios
Potable Water Distribution and Treatment Pipeline Isolation
Used for shutoff and isolation in potable water distribution equipment, water treatment systems, and associated piping. This series is NSF 61/372 certified and meets applicable safe drinking water requirements for potable water applications.
Sour Oil and Gas Pipeline Isolation
Used for shutoff and isolation of small-bore piping in sour gas applications in the oil and gas industry. This series meets applicable NACE MR0175 requirements and is suitable for sour oil and gas service conditions.
Hazardous Area Automated Shutoff Isolation
Used for automated shutoff and isolation in hazardous locations with explosive atmospheres. This series is ATEX certified, features an anti-static device, and includes an ISO 5211 mounting pad to support actuator configuration for automated operation.
Selection points
Full-Port Flow Passage
The S85 Series is a full-port ball valve designed to minimize the impact of valve bore reduction on media flow, making it suitable for applications requiring unobstructed piping flow.
CF8M Body and Ball with 316 Stem Materials
The body and ball are manufactured from ASTM A351 CF8M, while the stem is manufactured from ASTM A479 Type 316, providing a selection basis for applications requiring specified stainless steel body, ball, and stem materials.
Integrally Cast ISO 5211 Automation Mounting Pad
The valve features an integrally cast ISO 5211 mounting pad compatible with Bray modular actuators for valve automation configurations.
Bottom-Entry Blowout-Proof Stem Design
The S85 features a bottom-entry blowout-proof stem design that prevents the stem from being ejected by pipeline pressure.
Live-Loaded Self-Adjusting Stem Packing Seal
The stem packing incorporates a live-loaded self-adjusting design that compensates for packing wear and temperature changes to maintain stem sealing performance and reduce adjustment requirements.
Antistatic Design for Hazardous Environments
The S85 is equipped with an antistatic device to prevent static electricity buildup, making it suitable for industrial environments with explosion hazards; product documentation indicates ATEX certification.
Installation & maintenance notes
NPT Threaded Connection Compatibility
The S85 Series uses NPT threaded end connections. During installation, confirm that the valve NPT threaded connections match the piping connection specifications.
Actuator Mounting Interface Use
The S85 Series features an integrally cast ISO 5211 mounting pad. When configuring an automated actuator, use this mounting interface for connection.
FAQ
How does the S85 threaded ball valve work?
The S85 uses a 2-piece construction and controls fluid flow by rotating the ball. The stem works with the packing to provide sealing. The seat material is RPTFE, and the bottom-entry design prevents the stem from being blown out by line pressure.
When selecting a valve, how does the S85 blowout-proof stem design affect safety?
The blowout-proof stem design uses a bottom-entry construction to reduce the risk of stem ejection under line pressure, improving safety in hazardous environments while supporting long-term sealing performance and operational reliability.
What applications are covered by the S85 certifications?
This series has ATEX, CRN, NACE MR0175, NSF 61/372, PED, PE(S)R, and SIL certifications. It is suitable for oil and gas, potable water, and other industrial automation applications requiring zero leakage.
What are the key maintenance considerations for S85 Series valves?
The replaceable seat and stem packing design simplifies maintenance. Live-loaded, self-adjusting stem packing automatically compensates for temperature changes and wear, reducing maintenance frequency while maintaining sealing performance.
How can the specific model and configuration be confirmed?
The specific configuration must be confirmed based on the actual model and application conditions. If required, provide the process medium, temperature, pressure, and end-connection details for further selection assistance.
