Bray/McCannalok
The Bray/McCannalok series offers rugged reliability in a proven design. Large diameter Bray resilient seated butterfly valves have the same beneficial design features as the smaller diameter valves.
The internal disc-stem drive connection eliminates exposed retaining hardware and the seat completely isolates the valve body & stem from the line media. This dry body and stem (shaft) design is important for preventing internal corrosion and is particularly beneficial for power plants that use seawater for the circulating water service.
Applications:
Steam isolation
Condensate
Boiler feedwater
Steam drain and vent
Fuel oil
Triple offset butterfly valves
Bray Tri-Lok
One of the primary concerns of the industry is safety, and rightfully so, especially in a nuclear plant. The industry needs reliable, proven valves that limit or extinguish the potential for hazardous situations. Bray valves are designed for just that.
Bray/McCannalok and Tri Lok high performance valves are engineered to perform under the harshest conditions of the industry and can be relied upon to deliver dependability, versatility, and reliability at the most affordable price available.
Steam isolation
High pressure, high temperature requiring tight shutoff metal-to-metal seating
Natural gas shutoff
Critical ESDV and BDV
Bray double and triple offset valves present tremendous cost savings over other types. They offer considerable space savings, usually by a third or more. Being smaller, they are much lighter, up to ten percent. Space and weight savings are oftentimes critical and Bray valves have the clear advantage. The Bray/McCannalok high performance butterfly valve's innovative design offers rugged reliability and extremely easy maintenance in the field.
The strength of Bray valves
Zero Leakage
Part of the strength of Bray valves is that they offer both resilient seated and metal seated designs that provide zero leakage. Both McCannalok double offset and Tri Lok triple offset butterfly valves are factory tested with both high pressure (at 1.1 times rating) water and low pressure gas for bi-directional zero leakage shutoff. Bray Flow-Tek M4 severe service ball valves with all-metal seats are tested to zero leakage for turbine water induction prevention, superheater drains, inlet/outlet drains, high point boiler vents, boiler blowdown isolation, main steam stop valves, and other critical services. All stem designs incorporate a blow-out proof feature.

Certified & Trusted
By thousands of companies worldwide
To meet ASME B31.1 Power Piping Code requirements, Bray valves comply with ASME B16.34 and have been assessed and certified by multiple global certification authorities such as Lloyd’s, DNV, and UL.
For prevention of water damage to steam turbines used in fossil-fuel-fired electrical power generation, ASME’s TDP-1 is considered in the design of critical severe service ball valves.
Certifications
Our performance tested products are in compliance with a variety of global certifications and approvals, including Lloyd's Register, UL, ABS and more.
