Bray/McCannalok Double Offset High Performance Butterfly Valves
The Bray/McCannalok high performance butterfly valve's innovative design offers rugged reliability and extremely easy maintenance in the field. Independent and internal tests prove Bray/McCannalok’s superior service life capability, with zero leakage shutoff. The Bray/McCannalok High Performance Valve delivers the highest quality and highest value available for meeting today’s demanding requirements.
Available with proven bi-directional fire safe seats for reliable control of flammable and hazardous fluids in petroleum, petrochemical, chemical and other high-risk applications.The fire safe design combines superior performance, extended service life and compliance with the most demanding worldwide fire-test standards – before, during and after a fire!
The Bray/McCannalok’s unique, patented design received Chemical Processing’s Vaaler Award for Best Product shortly after it was introduced. The simple, innovative design offers rugged reliability and extremely easy maintenance in the field. Independent and internal tests have proven Bray/McCannalok’s superior service life capability, with zero leakage shutoff through over 100,000 cycles. The Bray/McCannalok valves can be automated inexpensively with Bray’s pneumatic and electric actuators. The Bray/McCannalok High Performance Valve delivers the highest quality and highest value available for your requirements.
After a test of over 100,000 cycles at 720 psi, the seat remained in excellent condition, continuing to provide a bi-directional zero leakage seal. Even after more than 878,000 cycles at 2 psi, the Bray/McCannalok High Performance Valve still sealed zero leakage in both directions.
Bray/McCannalok valves handle a wide range of conditions and media such as corrosive chemicals, water, gases, acids, alkalis, hydrocarbons plus many other fluids. Bray’s standard valve line has been specifically designed to meet most applications. When applications demand special requirements, Bray offers valves and materials that meet these needs.
Bray/McCannalok High Performance Valves are available with proven bi-directional fire safe seats on:
Wafer, Lug and Double Flange bodies:
• ASME Class 150 2½-40"(65-1000mm)
• ASME Class 300 2½-24"(65-600mm)
• ASME Class 600 3-14"(80-350mm)
For reliable control of flammable and hazardous fluids in petroleum, petrochemical, chemical and other high-risk applications, the fire safe DESIGN combines superior performance, extended service life and compliance with the most demanding worldwide fire-test standards – before, during and after a fire!
In normal service, the Fire Safe combination resilient/metal seat seals zero-leakage in both directions of line media flow through the full rated pressure and temperature ranges. When closed, the disc remains compressed against the resilient mechanically loaded seat, which is securely locked in place by a full-faced retainer. Line media pressure strengthens the seal.
In the event of a fire, if excessive heat destroys the resilient seat materials, either partially or completely, the seat provides a constant metal–to–metal backup seal.
In actual fire conditions, line pressure is immediately reduced and the entire area is hosed down. The resulting pressure drop and rapid cool down causes many valves to fail. The Fire Safe design does not rely on line media pressure to seal, therefore the valve offers superior low pressure performance to competitive designs. The Inconel® metal seat functions as a spring mechanism, which allows for expansion and contraction without breaking contact with the disc. Additionally, the Inconel seat offers better corrosion and heat resistance and greater strength than the stainless steel seats commonly used.
The Bray/McCannalok delivers proven fire safe protection not only in the lab, but also where it counts the most – in the field.
Fire Safe Seat Operation
The seat assembly in normal service contacts the disc with both the resilient seat and metal seat. During and after a fire, when the resilient seat has been partially or completely destroyed, the metal seat provides a positive seal by remaining in constant contact with the disc in either direction of media flow.

Tri Lok Triple Offset Metal Seated Butterfly Valves
Compared to gate, globe or ball valves of the same size and pressure class, Tri Lok provides space and weight savings while minimizing installation and maintenance costs.
Tri Lok is a premier isolation valve, well suited for operation in light vacuum to high-pressure applications. The standard, non-rubbing, metal-to-metal sealing system is inherently fire-safe. Applications requiring absolute zero leakage are ideally suited for triple offset technology.
Valve bodies and discs are available in WCB Carbon Steel and CF8M Stainless Steel as standard. Low-temperature Carbon Steel, Duplex Stainless Steel, Monel, Hastelloy® and NiAB are also available. The discs primary function is to "carry" the seal ring. As such, the disc material is commonly the same material as the body to allow full pressure/temperature rating and maintain uniform thermal expansion at elevated temperature. Standard stem materials are 17-4PH, 410 Stainless Steel and XM-19 (Nitronic®). Seat, seal ring and remaining trim are selected to meet the required mechanical properties while providing sufficient corrosion resistance. While the previously mentioned materials are defined as standard, custom engineered configurations are also available.
Specifications:
Size Range: 3” – 48” (80mm – 1200mm)
Body Style: Wafer, Lug, Flanged and Gate
Temperature Range: -58°F to 842°F (-50°C to 450°C)
Pressure Ratings: ASME Class 150, 300 and 600
Shutoff Rating: Zero Leakage
Body Materials: Carbon Steel, Stainless Steel & Other Materials
Disc Materials: Carbon Steel, Stainless Steel & Other Materials
Stem Materials: 410 SS, 17-4Ph, & XM-19
